Hi, If I install version 2.1, will it leave version 2.0 there, will it ask me to remove version 2.0 first, or will it erase it automatically? Thanks, Paul
The installation should take care of replacing old files and registry updates. However it is always a good practice to uninstall old version prior to installing new version.
It's fully supported to have all of them installed side by side. However note that the templates are overwritten, and that VS and Blend will automatically pick up v2.1 (in most cases changing your existing projects as well). If you need to set the references to 2.0, you need to manually add the reference by browsing to them.
