Some projects' dependencies contain unexplaine

Question

I have a couple of projects where under Dependencies there are one or two branches of code analyzers like this:

I tried the right mouse click on every branch as explaind here but there is no option to configure them and I also searched for *.ruleset files insinde the solution, I also check the packages as shown in the docs but there is nothing like that anywhere.

There is also nothing suspicious in the .csproj files, just some nuget packages that I've installed but nothing analyzer related.

How do I get rid of them? They give me warnings when I reference such projects in other solutions and nuget restore doesn't fix it either:

I have no idea where they come from. Some projects have them and others don't. However, they seem to somehow be related to ASP.NET Core or MVC packages that are installed in those projects.

Answer 1

I've fixed the warnings by deleting the microsoft.codeanalysis.analyzers folder and executing nuget restore. They are still under Dependencies but at least the exclamation marks are gone.

I've also managed to remove the analyzers by adding the <ExcludeAssets>analyzers</ExcludeAssets> directive to each AspNetCore package:

<PackageReference Include="Microsoft.AspNetCore.Mvc" Version="2.1.3">
  <ExcludeAssets>analyzers</ExcludeAssets>
</PackageReference>
<PackageReference Include="Microsoft.AspNetCore.Http.Abstractions" Version="2.1.1" >
  <ExcludeAssets>analyzers</ExcludeAssets>
</PackageReference>

Now they're finally gone.

Search Gcop in nuget package manager removes the installed packages prefixed with GCop. this will remove the code analyzer references from your project
