How do I find an INamedTypeSymbol for an instance of ITypeParameterSymbol?

I want to iterate over parameters of a particular INamedTypeSymbol and recurse into them in the case those type parameters are generic themselves. However I can't do that, because the type parameters are returned as ITypeParameterSymbol and the generic parameters are only available on INamedTypeSymbol.

You want TypeArguments, not TypeParameters.

TypeParameters returns the declared type parameters of the member declaration (the open/unconstructed generic type). These are never named types.

TypeArguments returns the types that have been substituted (if the type is a closed/constructed type).
