View type information for types not in the source

[ivanz]

It would be great if we can see where types are defined where the type is not part of the source code. Right now if I can't "go to definition" or "peek definition" - I have no idea where is this type defined.

It would be amazing if we could get the same behaviour as in Visual Studio IDE where it displays a "[from metadata]" tab with the assembly name, namespace and list of members in C# code, but even just knowing which assembly and namespace the type comes from would be a start.

Edit:

I noticed one case where extra information is displayed and that's for field/property declaration's type:

Thanks for the request @ivanz. Adding the "Metadata as Source" that VS has for symbols not defined in source is definitely something we want to do for VS Code. Dupe of #165.
