Banned Symbols Analyzer partial ban [Answered]

I currently ban DbContext.Set<T>() methods in my project using https://github.com/dotnet/roslyn-analyzers/tree/main/src/Microsoft.CodeAnalysis.BannedApiAnalyzers

M:Microsoft.EntityFrameworkCore.DbContext.Set``1
M:Microsoft.EntityFrameworkCore.DbContext.Set``1(System.String)

M:Microsoft.EntityFrameworkCore.DbContext.Set``1
M:Microsoft.EntityFrameworkCore.DbContext.Set``1(System.String)

but I'd like to ban them only partially. Meaning, I want to disallow concrete types, but allow generic parameters. For example

public void Foo<T>()
{
    _ctx.Set<T>(); // allowed
    _ctx.Set<Product>(); // disallowed
}

public void Foo<T>()
{
    _ctx.Set<T>(); // allowed
    _ctx.Set<Product>(); // disallowed
}

is that even possible?

You could write your own analyzer

Sure I could, but a) One already exists, so maybe it does already have this feature b) That would mean trying to make sense of the Roslyn APIs, and I'd rather learn ancient Sumerian in cursive

You cannot Your only option is writing an analyzer
