Code completion when typing lambda expression parameters

[Rpinski]

When I start typing a new lambda expression, say

s => s.Parent is EntityDeclaration

then after entering the first s (before =>) a code completion window is shown. If I don't escape it, it will insert the first entry found for "s" after typing the whitespace. Since I'm declaring a parameter here, no code completion should be done. Of course, after => code completion would still be desirable for users.

Visual Studio behaves as expected here, by the way.

What Visual Studio does in that case: It shows the parameter name typed before ("s" in my example) as first entry of code completion list. So after typing a whitespace the parameter name will still stay the same.
Apparently this behaviour based on the type expected at that location (e.g. when passing a method parameter that needs to be a delegate).

The NRefactory code completion engine already supports this feature; it just isn't wired up to the AvalonEdit CC window correctly. See issue #275.

+1, this issue is extremely annoying
