+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and maintainers pledge to make participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, sex characteristics, gender identity and expression,
+level of experience, education, socio-economic status, nationality, personal
+appearance, race, religion, or sexual identity and orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment
+include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or
+  advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic
+  address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, issues, and other contributions
+that are not aligned to this Code of Conduct, or to ban temporarily or
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies within all project spaces, and it also applies when
+an individual is representing the project or its community in public spaces.
+Examples of representing a project or community include using an official
+project e-mail address, posting via an official social media account, or acting
+as an appointed representative at an online or offline event. Representation of
+a project may be further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting the project team at opensource+actions/setup-dotnet@github.com. All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and appropriate to the circumstances. The project team is
+obligated to maintain confidentiality with regard to the reporter of an incident.
+Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good
+faith may face temporary or permanent repercussions as determined by other
+members of the project's leadership.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
+available at https://www.contributor-covenant.org/version/1/4/code-of-conduct.html

 ## Environment Variables to use with dotnet
 
-Some environment variables may be necessary for your particular case or to improve logging. Some examples are listed below, but the full list with complete details can be found here: https://docs.microsoft.com/en-us/dotnet/core/tools/dotnet#environment-variables
+Some environment variables may be necessary for your particular case or to improve logging. Some examples are listed below, but the full list with complete details can be found here: https://docs.microsoft.com/en-us/dotnet/core/tools/dotnet-environment-variables
 
 - DOTNET_NOLOGO - removes logo and telemetry message from first run of dotnet cli (default: false)
 - DOTNET_CLI_TELEMETRY_OPTOUT - opt-out of telemetry being sent to Microsoft (default: false)
 - DOTNET_MULTILEVEL_LOOKUP - configures whether the global install location is used as a fall-back (default: true)
 
 Example usage:
-```
+```yaml
 build:
   runs-on: ubuntu-latest
   env:
     DOTNET_NOLOGO: true
   steps:
-    - uses: actions/checkout@master
-    - uses: actions/setup-dotnet@v1

-        dotnet-version: '3.1.100' # SDK Version to use.
+        dotnet-version: '3.1.x' # SDK Version to use.

+# v3 setup-dotnet
+
+Date: 2022-08-25  
+Status: Accepted
+
+# Context
+- GitHub-hosted Ubuntu and Windows runners have .NET versions pre-installed in system directories
+  - Ubuntu:`/usr/share/dotnet`
+  - Windows:`C:\Program Files\dotnet`
+- V1 version of Action installs .NET to the user's directory
+  - Ubuntu:`/home/runner/.dotnet`
+  - Windows: `C:\Users\runneradmin\AppData\Local\Microsoft\dotnet`
+- It means that action always downloads and installs .NET version even if it is pre-installed. Also after using the action all pre-installed .NET versions are unavailable because `DOTNET_ROOT` is overridden to the user's directory.
+The behavior is different for macOS runners because the pre-installation directory matches the one that is used by action. It means action can use pre-installed versions if they exist, which speeds up the customer's workflow.
+
+- The different behavior of the setup task on Ubuntu, Windows and macOS runners is unclear and confusing for customers.
+
+- .NET supports installing and using multiple versions of .NET SDK and .NET runtime side-by-side. .NET CLI will use the latest installed .NET SDK and .NET runtime versions if there is no global.json file containing a different version. This behavior is defined by .NET design (https://docs.microsoft.com/en-us/dotnet/core/versions/selection).
+
+- The action contains logic to handle inputs with wildcards, for example `5.0.x`, `5.0.*`, `5.x` or `5.*`. This logic uses metadata from `https://dotnetcli.blob.core.windows.net/dotnet/release-metadata/releases-index.json` to retrieve the list of available releases and get the latest release version for the specified major and/or minor version from the input. After that, installer script (`dotnet-install.ps1` for Windows or `dotnet-install.sh` for Linux and macOS) installs the required SDK using exact version as a parameter.
+
+# Proposal
+
+- Change .NET installation path for Windows and Ubuntu images to match the location of pre-installed versions by using `-InstallDir` (Windows) and `--install-dir` (Ubuntu) properties for installer scripts:
+https://docs.microsoft.com/en-us/dotnet/core/tools/dotnet-install-script
+
+- Simplify and in some cases fully get rid of logic for resolving wildcard versions and start relying on [official installer scripts provided by .NET Core team](https://github.com/dotnet/install-scripts).  
+The execution `dotnet-install.ps1 -Channel 5.0` installs the latest patch version for 5.0 SDK. If SDK is in the prerelease phase, the latest prerelease version (preview or rc) will be installed.
+
+Inputs with wildcards in the patch tag (`5.0.x` or `5.0.*`) can be handled by passing major and minor versions to the installer script directly as a `channel` parameter. This parameter supports two-part version in `X.Y` format as input value ([see installer scripts documentation](https://docs.microsoft.com/en-us/dotnet/core/tools/dotnet-install-script)).
+
+Inputs with wildcards in the minor tag (`3.x` or `3.*`) can be handled like that:
+1. The request is sent to MS dist and the `releases.json` file is got
+2. The action gets the latest possible channel version out of retrieved `releases.json` that satisfies input major tag (e.g. for `3.x` nowadays it's `3.1`) 
+3. Retrieved channel version is passed to installer script directly as `channel` parameter.
+
+> **Note:** Using the `channel` parameter of the MS .NET installer scripts will allow us to use the `quality` parameter as well. This functionality is also asked for by our customers.
+
+# Breaking changes
+- The presence of pre-installed .NET versions that are higher than the version that the users specify in the setup task can be breaking for some customers, who expect only one installed .NET version on the runner after using the setup task. If a user doesn't have .NET version specified in project file, the `dotnet` will use the latest installed version instead of provided in the setup task.  
+> **Note:** It is the biggest deal in this ADR.
+
+Previously, when a user would specify a .NET version, this exact version was used by the `dotnet` command by default (because it was installed in a separate folder and there were no other.NET versions in that folder)  
+In the proposal, the specified version will be installed on the machine but the latest version will be used by the `dotnet` command by default (because specified version will be installed alongside with pre-installed .NET versions).  
+Based on [official .NET documentation](https://docs.microsoft.com/en-us/dotnet/core/versions/selection), it is expected behavior and how it works on user's local machine with multiple installed .NET versions but some customer's workflows could be broken because they already rely on current behavior.
+
+To avoid breaking customers, we will need to release a new major task version (v3).
+
+# v3-preview
+There will be a v3-preview branch that will be created for development and testing. Any changes will first be merged into the v3-preview branch. After a period of testing & verification, the v3-preview branch will be merged into the main branch and a v3 tag will be created. Any GitHub public documentation and starter workflows that mention setup-dotnet will then be updated to use v3 instead of v2:
+- [README.md](https://github.com/actions/setup-dotnet/blob/main/README.md)
+- [action.yml](https://github.com/actions/setup-dotnet/blob/main/action.yml)
+- [GitHub docs](https://docs.github.com/en/actions/guides/building-and-testing-net#using-a-specific-net-version)
+- Starter-workflow yamls: [#1](https://github.com/actions/starter-workflows/blob/main/ci/dotnet.yml#L17), [#2](https://github.com/actions/starter-workflows/blob/main/ci/dotnet-desktop.yml#L72)
+
+# Consequences
+- Customers will be able to use pre-installed .NET versions with setup-dotnet action on Windows and Ubuntu

+## Contribute documentation
+
+Documentation is a super important, critical part of this project. Docs are how we keep track of what we're doing, how, and why. It's how we stay on the same page about our policies and how we tell others everything they need to be able to use this project or contribute to it. 
+
+Documentation contributions of any size are welcome! Feel free to contribute even if you're just rewording a sentence to be more clear, or fixing a spelling mistake!
+
+**How to contribute:**
+
+Pull requests are the easiest way to contribute changes to git repos at GitHub. They are the preferred contribution method, as they offer a convenient way of commenting and amending the proposed changes.
+
+- Please check that no one else has already created a pull request with these or similar changes
+- Use a "feature branch" for your changes. That separates the changes in the pull request from your other changes and makes it easy to edit/amend commits in the pull request 
+- Make sure your changes are formatted properly and consistently with the rest of the documentation
+- Re-read what you wrote, and run a spellchecker on it to make sure you didn't miss anything
+- If your pull request is connected to an open issue, please, leave a link to this issue in the `Related issue:` section
+- If you later need to add new commits to the pull request, you can simply commit the changes to the local branch and then push them. The pull request gets automatically updated
+
+**Once you've filed the pull request:**
+
+- Maintainers will review your pull request
+- If a maintainer requests changes, first of all, try to think about this request critically and only after that implement and request another review
+- If your PR gets accepted, it will soon be merged into the main branch. But your contribution will take effect only after the release of a new version of the action and updating the major tag
+> Sometimes maintainers reject pull requests and that's ok! Usually, along with rejection, we supply the reason for it. Nonetheless, we still really appreciate you taking the time to do it, and we don't take that lightly :heart:
+
+## Contribute code
+
+We like code commits a lot! They're super handy, and they keep the project going and doing the work it needs to do to be useful to others.
+
+Code contributions of just about any size are acceptable!
+
+The main difference between code contributions and documentation contributions is that contributing code requires the inclusion of relevant tests for the code being added or changed. Contributions without accompanying tests will be held off until a test is added unless the maintainers consider the specific tests to be either impossible or way too much of a burden for such a contribution.
+
+**How to contribute:**
+
+Pull requests are the easiest way to contribute changes to git repos at GitHub. They are the preferred contribution method, as they offer a convenient way of commenting and amending the proposed changes.
+
+- Please check that no one else has already created a pull request with these or similar changes
+- Use a "feature branch" for your changes. That separates the changes in the pull request from your other changes and makes it easy to edit/amend commits in the pull request
+-  Format, build and test changes
+- Make sure your changes are well formatted and that all tests are passing
+- If your pull request is connected to an open issue, please, leave a link to this issue in the `Related issue:` section
+- If you later need to add new commits to the pull request, you can simply commit the changes to the local branch and then push them. The pull request gets automatically updated
+
+**Learn more about how to work with the repository:**
+
+- To implement new features or fix bugs, you need to make changes to the `.ts` files, which are located in the `src` folder
+- To comply with the code style, **you need to run the `format` script**
+- To transpile source code to `javascript` we use [NCC](https://github.com/vercel/ncc). **It is very important to run the `build` script after making changes**, otherwise your changes will not get into the final `javascript` build
+
+**Learn more about how to implement tests:**
+
+Adding or changing tests is an integral part of making a change to the code. 
+Unit tests are in the `__tests__` folder, and end-to-end tests are in the `workflows` folder, particularly in the [workflow.yml](https://github.com/actions/setup-dotnet/blob/main/.github/workflows/workflow.yml).
+
+- The contributor can add various types of tests (like unit tests or end-to-end tests), which, in his opinion, will be necessary and sufficient for testing new or changed functionality
+- Tests should cover a successful execution, as well as some edge cases and possible errors
+- As already mentioned, pull requests without tests will be considered more carefully by maintainers. If you are sure that in this situation the tests are not needed or cannot be implemented with a commensurate effort - please add this clarification message to your pull request
+
+**Once you've filed the pull request:**
+
+- CI will start automatically with some checks. Wait until the end of the execution and make sure that all checks passed successfully. If some checks fail, you can open them one by one, try to find the reason for failing and make changes to your code to resolve the problem
+> Sometimes you may need to update the installers you can do this with the `npm run update-installers` command
+- Maintainers will review your pull request
+- If a maintainer requests changes, first of all, try to think about his request critically and only after that implement and request another review
+- If your PR gets accepted, it will soon be merged into the main branch. But your contribution will take effect only after the release of a new version of the action and updating the major tag
+> Sometimes maintainers reject pull requests and that's ok! Usually, along with rejection, we supply the reason for it. Nonetheless, we still really appreciate you taking the time to do it, and we don't take that lightly :heart:
+
+## Provide support on issues
+
+Helping out other users with their questions is an awesome way of contributing to any community. It's not uncommon for most of the issues on open source projects to be support-related questions by users trying to understand something they ran into or find their way around a known bug.
+
+**To help other folks out with their questions:**
+
+- Go to the [issue tracker](https://github.com/actions/setup-dotnet/issues)
+- Read through the list until you find something that you're familiar enough with to answer to
+- Respond to the issue with whatever details are needed to clarify the question, or get more details about what's going on
+- Once the discussion wraps up and things are clarified, ask the original issue filer (or a maintainer) to close it for you
+ 
+*Some notes on picking up support issues:*
+
+- Avoid responding to issues you don't know you can answer accurately
+- Try to refer to past issues with accepted answers as much as possible. Link to them from your replies
+- Be kind and patient with users. Often, folks who have run into confusing things might be upset or impatient. This is natural. If you feel uncomfortable in conversation with them, it's better to stay away or withdraw from the issue.
+
+ > If some user is violating our code of conduct [standards](https://github.com/actions/setup-dotnet/blob/main/CODE_OF_CONDUCT.md#our-standards), refer to the [Enforcement](https://github.com/actions/setup-dotnet/blob/main/CODE_OF_CONDUCT.md#enforcement) section of the Code of Conduct to resolve the conflict
+ 
+## Review pull requests
+ 
+Another great way to contribute is to review pull request. Please, be extra kind: people who submit code/doc contributions are putting themselves in a pretty vulnerable position, and have put time and care into what they've done (even if that's not obvious to you!) Please, always respond with respect, and be understanding, but don't feel like you need to sacrifice your standards for their sake, either.
+ 
+**How to review:**
+
+- Go to the [pull requests](https://github.com/actions/setup-dotnet/pulls)
+- Make sure you're familiar with the code or documentation is updated, unless it's a minor change (spellchecking, minor formatting, etc.)
+- Review changes using the GitHub functionality. You can ask a clarifying question, point out an error or suggest an alternative. 
+> Note: You may ask for minor changes - "nitpicks", but consider whether they are real blockers to merging or not
+- Submit your review, which may include comments, an approval, or a changes request
