can blend 2 and blend 3 co exist peacefully ?
Also can visual studio tools for silverlight 2 and 3 co exist ?
i am using both blend 2 and 3 which is working fine.
and about silverlight 2 and 3
you have to remove 2 for installing silverlight 3.
Visual Studio Tools for SL 2 and SL 3 unfortunately do not co-exist for VS2008. The Blend releases should be fine.
We're working to improve this in VS2010, so that it supports multiple versions of Silverlight at the same time.
