First, let me say that I love the external sources feature--it allows me to
download the .NET Reference Sources on demand, even though the proper
versions for my OS are not available (Windows 7 RC).
I have already downloaded the entire pre-packaged Windows 7 Reference
Sources from the Microsoft site, and I was wondering if I can override the
Reference Source integration so that ReSharper pulls source files from my
local copy rather than the Microsoft servers. I see there is an option
called "folder substitutions", but I'm not sure if I can use this feature as
a solution, and if so, how configure it properly.
