How to add a custom code analyzer to a project without nuget or VSIX?

Question

I want to write a custom code analyzer in Visual Studio 2015 for a C# ConsoleApplication. For this reason I don't want to create a seperate "Analyzer with Code Fix" project from template, because this requires to add this analyzer in my projects as nuget package.

Is it possible, to add a analyzer reference manually? I would like to reference the analyzer without nuget.

You can right click on 'Analyzers' and select an analyzer dll. Better question would be why you don't want to use nuget though. — Jeroen Vannevel, Nov 27 '16 at 16:12
@Jeroen Vannevel because why bother with nuget if it's only a custom local analyzer? — Monsignor, Dec 19 '17 at 10:33

If you add an analyzer as Nuget and check the content of your project, you'll see that only an <Analyzer Include="..." /> item is added. You can do the same manually. Also, you can do this in the .csproj.user file as well, so you can also do it locally, and not commit this change to your SCM.

I've found in VS2017 at least that if you just add an tag to your project, you only get warnings when you build, not as you type. You seem to need to have the nuget package in the packages.config and the tag to get the warnings both when you're editing code and compiling. – John Hall Oct 25 '18 at 10:59

Beware that `` requires a path to an assembly, and won't work with csproj – Métoule Jun 16 '23 at 09:48

You can add analyzer via project reference with OutputItemType set to Analyzer:

<ItemGroup>
  <ProjectReference Include="..\Analyzers\Analyzers.csproj">
     <ReferenceOutputAssembly>false</ReferenceOutputAssembly>
     <OutputItemType>Analyzer</OutputItemType>
   </ProjectReference>
</ItemGroup>
