The new intellisense behavior for VB hinders more than it is useful at the moment. Beneath strange behavior the performance, specially on large files (> 5.000 lines), is very bad. Sometimes the IDE is frozen for 10 to 30 seconds while R# is opening the intellisense popup. Automatic completion is invoked on the wrong places (i have posted a number of examples here). Currently i have seen that you can't input double values without problems. I call the constructor of a class which takes double parameters
dim myvar = new ValueClass(0.0, 0.0)
After entering the decimal point and the zero, intellisense pops up and when i enter the comma R# completes my input to 0.CompareTo. There are a couple of similar issues. Somtimes i wish a developer would sit beneath me that he can see what happens. It's sometimes hard to describe.
I think i will disable R# intellisense until it is improved.
