TypeHelper.IsMatch should check OriginalDefinition as well to work with generics

[andrei-epure-sonarsource]

TypeHelper.IsMatch checks only the typeSymbol.

However, this won't work for generic collections for which the typeSymbol.SpecialType contains the concrete type - e.g. List<string>, whereas the generic type definition is List<T>.

To fix this, the OriginalDefinition.SpecialType should be compared as well, like below.

    return type.Matches(typeSymbol.SpecialType) ||
            type.Matches(typeSymbol.OriginalDefinition.SpecialType) ||
            type.Matches(typeSymbol.ToDisplayString()) ||
            type.Matches(typeSymbol.OriginalDefinition.ToDisplayString());
    }

@andrei-epure-sonarsource The current approach that was taken, was to say that when calling this method, if you can have generics, then you should ensure the OriginalDefinition is passed.
