Add signature help support for .NET methods

[kaylaerdmann]

C# methods are using the suggestions documentation window to show parameter hints (see below). .

The information contained this suggestion detail needs to be used in parameter hints. Currently the parameter hints UI does not display for c# methods.

@kapilmb has been working on this already, maybe we can get it in for 0.9.0 in January?

[kapilmb]

Yes, I think we will have it merged by then.

This looks like it's working now?

Nah, that's just the "description" of the completion. Signature help is the thing that comes after you type .Add( and you get the parameter list of the method as a popup above as you type. This is definitely one of the gaps in PSES.
