Excluding a file from the roslyn analyzers

Question

Since we have a lot of generated code, some roslyn analyzers go crazy about this code. Is there any way to exclude some files from analyzers?

Answer 1

There is currently no way to explicitly say "don't run my analyzer on generated code". You have to handle this manually.

I believe the heuristics used are as follows. (I took this list from Giovanni Bassi, one of the authors of Code Cracker) A file is auto generated if any of the following conditions are met:

It has one of these attributes:

• DebuggerNonUserCodeAttribute
• GeneratedCodeAttribute

The file path contains:

• *.g.cs
• *.designer.cs
• *.AssemblyInfo.cs
• *.generated.cs
• *.g.cs
• *.g.i.cs
• *.AssemblyAttributes.cs
• TemporaryGeneratedFile_*.cs

A header comment contains:

• <auto-generated>

The Code Cracker project has a number of extension methods for detecting generated files. Check out GeneratedCodeAnalysisExtensions
