It's disappointing to see that ReSharper 3.0 as a commercial product has no document or sample for creating plugins. C'mon guys, this is not an open source product where you leave the documents for plugins like this:
And even the current unfinished document is for v 2.5.
Even PowerToys source code http://www.jetbrains.net/confluence/display/ReSharper/PowerToys+Sources which was my last hope is an MSI file and doesn't install because it doesn't find ReSharper 2.5 installed. Where on the earth a company publish sample code as installation files? (except Microsoft of course!).
Sorry, I'm a bit upset at the moment. Can someone please shed some light on this issue?
