Summary

At the beginning it seemed like a good idea to include analyzers in the IDE extensions. Analyzers were available in every project/solution without necessity reference in every project/solution.

The main issue is that the analyzers are "bound" only to the IDE, diagnostics will be displayed in the IDE but not during build, command-line build or CI build.

The desired state is that analyzers are "bound" to the project/solution, regardless of the IDE or extension installed.

Best Practice

• Install extension to have refactoring and code fixes for compiler diagnostics.
• Install NuGet package(s) with analyzers.
  • Add package reference to yourDirectory.Build.props file which is located at the root of your repository.

Directory.Build.props

<ItemGroup>  <PackageReferenceInclude="roslynator.analyzers"Version="<VERSION>">    <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>    <PrivateAssets>all</PrivateAssets>  </PackageReference>  <PackageReferenceInclude="roslynator.formatting.analyzers"Version="<VERSION>">    <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>    <PrivateAssets>all</PrivateAssets>  </PackageReference></ItemGroup>

When it will be removed?

Probably the best opportunity would be a moment when a new major version of Visual Studio is released. It usually means that major version of Roslynator is released as well.

Depending on when the next major version of VS will be released, analyzers could be removed from extension earlier, but not at least several months after this announcement.
