.NET project file analyzers

is a NuGet package containing Roslyn (static code) analyzers that report issues on .NET project files.

Installation

To use the analyzers, you must include the analyzer package in your project file:

<Project Sdk="Microsoft.NET.Sdk">

  <ItemGroup>
    <PackageReference Include="DotNetProjectFile.Analyzers" Version="*" PrivateAssets="all" />
  </ItemGroup>

</Project>

Or via the command line:

dotnet package add DotNetProjectFile.Analyzers

Configuration

Additional files

To fully benefit from these analyzers it is recommended to add the project file (and imported projects/props) as additional files.

To add a project file:

<Project Sdk="Microsoft.NET.Sdk">

  <ItemGroup>
    <AdditionalFiles Include="*.??proj" Visible="false" />
  </ItemGroup>

</Project>

To add a props file:

<?xml version="1.0" encoding="utf-8"?>
<Project>

  <ItemGroup>
    <AdditionalFiles Include="../props/{file_name}" Link="Properties/{file_name}" />
  </ItemGroup>

</Project>

Sonar integration

By default, results by .NET project file analyzers are not added to Sonar's reporting. Read here how to configure this correctly.
