Runtime Environment:
 OS Name:     Mac OS X

VS Code version: 1.14.2 C# Extension version: 1.11.0

Steps to reproduce

Create a local function, and make a call to it:

static void main(string[] args)
{
    var flag = LocalFunction(1);
    bool LocalFunction(int i)
    {
        return i > 0;
    }
}

Expected behavior

1. When typing arguments for the call to the local function, in var flag = LocalFunction(1);, IntelliSense should be provided for the parameter hints.

2. When using the feature Trigger Parameter Hints <kbd>⇧</kbd><kbd>⌘</kbd><kbd>Space</kbd> it should trigger the parameter hints for the call to the local function.

Actual behavior

No IntelliSense provided for 1, and no parameter hints triggered for 2.

The problem here is that in the SignatureHelpService, we are first finding the containingType for the given invocation and then returning all the methods in that containingType with the same name as the method. In case of localFunction , the containing type is being returned as the Class name and not the main function .But I am not sure whether this is the problem with roslyn returning the incorrect containingType or a problem with the way we are finding the methodOverloads in omnisharp-roslyn.
