Can I use Microsoft.CodeAnalysis.BannedApiAnalyzers as a library to analyze source code in a folder?

[MartyIX]

I find BannedApiAnalyzers (doc) to be a robust analyzer for checking if source code contain forbidden API or not. I would like to use it as a library in the following way (pseudocode):

var results = BannedApiAnalyzer.Analyze(files, bannedSymbolsTxt);

My question is twofold:

1. Can I do it?
2. Should I actually do it or is it not a supported use case?

Thank you!

You cannot do this, it is not a supported use case. What you could do is use Roslyn itself to create a compilation for those files, add the banned api analyzer to that compilation, and then get all diagnostics.

I converged to the same approach as here: https://stackoverflow.com/questions/77051745/how-to-use-banned-api-analyzers-in-own-code to find out (as the guy) that CSharpSymbolIsBannedAnalyzer is unknown type.

So I guess it's not exported somehow. Or how can one overcome this?

[MartyIX]

The type itself is public: https://github.com/dotnet/roslyn-analyzers/blob/372f0d4dd91199e415482a1ee302ee27162b885b/src/Microsoft.CodeAnalysis.BannedApiAnalyzers/CSharp/CSharpSymbolIsBannedAnalyzer.cs#L13C25-L13C54 So I guess that it's not exported by its nuget package or something.

You'd have to actually show your project. At a guess, you're depending on the package as an analyzer, not as a reference; you'll likely need to do a bit of msbuild magic to get a proper reference.
