What helps me cope is that in Visual Studio you can type the extension method's name and ctrl-. to get an "import namespace" quick fix suggestion. It even works when you type it with wrong casing (which happens to me a lot because I'm a really lazy typist). I'm really glad the VS team has been putting more of those in.
