I want to install Visual Studio 2010 in parallel with 2008 version on Win7. Can this cause some problems?
We have a few machine running both VS05 and VS08 (on vista) so I suppose this combo won't harm either...
I'm running Visual Studio 2008 and Visual Studio 2010 Beta 1 side by side in Windows 7 (RTM) and I have yet to experience any issues.
I have both installed on my Windows 7 machine at the moment, and I haven't seen anything fishy. Now, I am only doing C# development (no web development or ASP).
If you are really unsure, setup a virtual machine and try installing both on there and seeing if there are any issues for your particular environment.
I have both side by side on my Windows 7 machine and haven't noticed any issues (Desktop, WPF, WCF, Web, or otherwise).
That being said, Visual Studio 2010 is still beta...and being such should not be installed on a production machine. Use a VM just to be safe.
One thing I've met is that M$ VS Version Selector selects VS2010 for most files, if you open them using windows explorer. Since I only test new features of vs2010, while using vs2008 in production, the event is usually unwanted. Big a deal? Not at all, since a visit to "Set associations" could fix it... Wonder if there are settings for the vs selector as well...?
