Overload resolution

[B1Z0N]

Is there an API that allows to do method resolution? So if I have a INamedTypeSymbol, name of a method, it's argument types, type arguments, return type, etc to return the right resolution of a method. Right now I need to specifically find which AppendFormatted will be called in custom interpolated string handler. But for that I'll need to rewrite method overload resolution myself, and that's a bad idea. I know that there are Binder APIs, but I can't find them anywhere in Roslyn.

There is not. That's because overload resolution needs more than that. It needs the actual expressions written, which may not have types yet.

If you need to do overload resolution, generate a new syntax tree with the code you are interested in, and get the semantic model for that to look at.

What do you mean by that? In which case expressions don't have a type? Is it about dynamic?

Passing things like null, default, new(), etc.
