Users running macOS can generally follow the Linux instructions (while installing the macOS equivalents of the dependencies).\n\n# Pre-Requisites\n\nYou will need the following software installed (regardless of OS):\n\n* [.NET SDK 8.0](https://dotnet.microsoft.com/download/dotnet/8.0)\n* [git](https://git-scm.com/downloads)\n\n## Linux Pre-Requisites\n\nLinux users will additionally need:\n\n* [Mono](https://www.mono-project.com/download/stable/) 6.12+\n* [bash](https://www.gnu.org/software/bash/)\n\nNote: Linux users cannot run the .NET Framework tests, as they are incompatible. For this reason, we recommend that users either work primarily in Windows, or verify their tests work as expected in a Windows VM, before submitting PRs.\n\n## Windows Pre-Requisites\n\nWindows users will additionally need:\n\n* .NET Framework 4.7.2 or later (part of the Windows OS)\n* [PowerShell 7+](https://learn.microsoft.com/powershell/scripting/install/installing-powershell-on-windows)\n\nEnsure that you have configured PowerShell to be able to run local unsigned scripts (either by running `Set-ExecutionPolicy RemoteSigned` from within PowerShell, or by launching PowerShell with the `-ExecutionPolicy RemoteSigned` command line switch).\n\n_Note that the built-in version of PowerShell may work, but is unsupported by us. If you have PowerShell-related issues, please make sure you have installed PowerShell 7+ and the command prompt you opened is for PowerShell 7+, and not the built-in version of PowerShell._\n\n# Command-Line Build\n\n1. **Linux users:** Open a terminal to your favorite shell.\n\n **Windows users:** Open PowerShell 7+.\n\n1. From the root folder of the source repo, this command will build the code & run all tests:\n\n `./build`\n\n To build a specific target (or multiple targets):\n\n `./build [target [target...]]`\n\n The common targets (case-insensitive) include:\n\n * `Restore`: Perform package restore\n * `Build`: Build the source\n * `Test`: Run all unit tests\n\n You can get a list of options:\n\n `./build --help`\n\n# Editing source\n\nThe primary projects for editing are:\n\n* `xunit.analyzers` (for code analysis)\n* `xunit.analyzers.fixes` (for automated fixes for issues raised in code analysis)\n* `xunit.analyzers.tests` (for unit tests of both above projects)\n\nThese are targeting our lowest common denominator for Roslyn (current version 3.11, the version that's supported in Visual Studio 2019 16.11).\n\nThere are also three projects which build against the latest version of Roslyn:\n\n* `xunit.analyzers.latest`\n* `xunit.analyzers.latest.fixes`\n* `xunit.analyzers.latest.tests`\n\nWhen running a command line build, we run a matrix of 4 test projects: Roslyn 3.11 vs. latest, and .NET Framework vs. .NET. It's important that you run `./build` (or `./build test`) from Windows before submitting PRs, because some bugs are often found only in one of the four combinations (and Mono cannot run the .NET Framework tests).\n\nYou will also occasionally see tests which only run in specific environments. Common `#if` statements you may see (or may need to use) include:\n\n* `#if NETFRAMEWORK` (only runs for .NET Framework)\n* `#if NETCOREAPP` (only runs for .NET)\n* `#if ROSLYN_LATEST` (only runs with latest Roslyn, which includes getting analysis test support to C# language > version 9)\n\nIn production code, we try to minimize these when possible, and prefer to fall back to use dynamic runtime environment detection when we can (as we'd like to light up features in newer versions of Roslyn when available). While this isn't always possible, it is generally a goal we try to achieve. In test code, we tend to use these to more frequently to ensure we have complete coverage of features that should be available dynamically (whether they are lit up based on `#if` or by runtime environment detection).\n" }, { "path": "LICENSE", "content": "Unless otherwise noted, the source code here is covered by the following license:\n\n\tCopyright (c) .NET Foundation and Contributors\n\tAll Rights Reserved\n\n\tLicensed under the Apache License, Version 2.0 (the \"License\");\n\tyou may not use this file except in compliance with the License.\n\tYou may obtain a copy of the License at\n\n\t\thttp://www.apache.org/licenses/LICENSE-2.0\n\n\tUnless required by applicable law or agreed to in writing, software\n\tdistributed under the License is distributed on an \"AS IS\" BASIS,\n\tWITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied.\n\tSee the License for the specific language governing permissions and\n\tlimitations under the License.\n\nThe source in src/xunit.analyzers.tests/Utilities/XunitVerifier.cs was adapted from code\nthat is covered the following license (copied from\nhttps://github.com/dotnet/roslyn-sdk/blob/35d5e46fd5c403194692c645d912a17d36ed74f5/LICENSE.txt):\n\n\tThe MIT License (MIT)\n\n\tCopyright (c) .NET Foundation and Contributors\n\n\tAll rights reserved.\n\n\tPermission is hereby granted, free of charge, to any person obtaining a copy\n\tof this software and associated documentation files (the \"Software\"), to deal\n\tin the Software without restriction, including without limitation the rights\n\tto use, copy, modify, merge, publish, distribute, sublicense, and/or sell\n\tcopies of the Software, and to permit persons to whom the Software is\n\tfurnished to do so, subject to the following conditions:\n\n\tThe above copyright notice and this permission notice shall be included in all\n\tcopies or substantial portions of the Software.\n\n\tTHE SOFTWARE IS PROVIDED \"AS IS\", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR\n\tIMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY,\n\tFITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

Analysis and fixes are only supported with C#.\n\n**Requirements**: xUnit.net v2 or v3. Supported in Visual Studio 2019, 2022, and 2026 (as well as via command line builds with Roslyn 3.11+). Other environments (such as Mono or JetBrains Rider) may be able to use these analyzers as well; support and issue resolution will be provided by those third parties and not by xUnit.net itself.\n\n**Documentation**: a list of supported rules is available at https://xunit.net/xunit.analyzers/rules/\n\n**Bugs and issues**: please visit the [core xUnit.net project issue tracker](https://github.com/xunit/xunit/issues).\n\n**Building**: see [BUILDING.md](https://github.com/xunit/xunit.analyzers/blob/main/BUILDING.md).\n\n> _**Note:** Our minimum supported versions of Visual Studio 2019, 2022, and 2026 align with the \"Baseline\" column of the \"Support for Older Versions\" table of [Visual Studio Product Lifecycle and Servicing](https://learn.microsoft.com/visualstudio/releases/2026/servicing-vs#support-for-older-versions), as these are the minimum versions supported by Microsoft. If you are experiencing issues with an older version of Visual Studio, please upgrade and verify the issue still exists before opening issues._\n\n## How to install\n\n- xUnit.net v3: the analyzer package is referenced by the main [`xunit.v3` NuGet package](https://www.nuget.org/packages/xunit.v3) out of the box. If you choose to reference [`xunit.v3.core`](https://www.nuget.org/packages/xunit.v3.core) instead, you can reference [`xunit.analyzers`](https://www.nuget.org/packages/xunit.analyzers) explicitly.\n\n- xUnit.net v2 2.3.0 and higher: the analyzer package is referenced by the main [`xunit` NuGet package](https://www.nuget.org/packages/xunit) out of the box. If you choose to reference [`xunit.core`](https://www.nuget.org/packages/xunit.core) instead, you can reference [`xunit.analyzers`](https://www.nuget.org/packages/xunit.analyzers) explicitly.\n\n- xUnit.net v2 2.2.0 and earlier: you have to install the [`xunit.analyzers` NuGet package](https://www.nuget.org/packages/xunit.analyzers) explicitly.\n\n## How to uninstall\n\n- If you are using xUnit.net v3 and do not wish to use the analyzers package, replace the package reference to [`xunit.v3`](https://www.nuget.org/packages/xunit.v3) with the corresponding versions of [`xunit.v3.core`](https://www.nuget.org/packages/xunit.v3.core) and [`xunit.v3.assert`](https://www.nuget.org/packages/xunit.v3.assert).\n\n- If you are using xUnit.net v2 2.3.0 or higher and do not wish to use the analyzers package, replace the package reference to [`xunit`](https://www.nuget.org/packages/xunit) with the corresponding versions of [`xunit.core`](https://www.nuget.org/packages/xunit.core) and [`xunit.assert`](https://www.nuget.org/packages/xunit.assert).\n\n- If you are using xUnit.net v2 v2.2.0 or earlier: remove the reference to the [`xunit.analyzers` NuGet package](https://www.nuget.org/packages/xunit.analyzers).\n\n## Analysis and Code Fix in Action\n\n![Analyzer in action animation](https://cloud.githubusercontent.com/assets/607223/25752060/fb4af444-316b-11e7-9e7c-fc69ade132fb.gif)\n\n# About xUnit.net\n\nxUnit.net is a free, open source, community-focused unit testing tool for C#, F#, and Visual Basic.\n\nxUnit.net works with the [.NET SDK](https://dotnet.microsoft.com/download) command line tools, [Visual Studio](https://visualstudio.microsoft.com/), [Visual Studio Code](https://code.visualstudio.com/), [JetBrains Rider](https://www.jetbrains.com/rider/), [NCrunch](https://www.ncrunch.net/), and any development environment compatible with [Microsoft Testing Platform](https://learn.microsoft.com/dotnet/core/testing/microsoft-testing-platform-intro) (xUnit.net v3) or [VSTest](https://github.com/microsoft/vstest) (all versions of xUnit.net).\n\nxUnit.net is part of the [.NET Foundation](https://www.dotnetfoundation.org/) and operates under their [code of conduct](https://www.dotnetfoundation.org/code-of-conduct).
