I finally got my hands on Visual Studio 2010 and decided to write my first WPF (Windows Presentation Foundation) application. I noticed some horrible performance while using the WPF editor in VS2010, as well as poor compilation times. At first I thought it was some teething problems with VS2010.
However, today I discovered it was Avast that was causing the performance problems with VS2010. The solution was simply to add my VS2010 projects directory to the exclusions list of the File System Shield. It was only necessary to exclude the write actions. Everything is working blazingly fast now.
I thought it would be a nice thing to share with others.
no need to add in file exclusions, all you need to do is, disable all shields for 10 minutes, F5, after project runs in browser reenable shields, avast automatically allows if for later
