I would strongly recommend not installing VS11 Developer Preview along side VS2010. Use a virtual machine or a separate partition, because you will have issues. My experience:
I installed VS11 dev preview when it first came out. Everything has been fine since then. Today, I go to install the MVC4 beta and I get an error message that says .NET 4.5 is incompatible. No problem, I'll uninstall .NET 4.5 and VS11.
After uninstalling, I fire up VS2010 and what do I see? A small dialog box that says "Unknown Error". How incredibly helpful. Am I wrong in thinking VS2010 has no dependency on .NET 4.5? Why would uninstalling VS11 completely brick VS2010? Has anyone
else experienced this? I'm repairing the installation now. If that doesn't work, I'm not sure what to try next. Unfortunately, formatting isn't an option or I would save myself the headache and do a clean OS install.

When you install .net 4.5 in will install in
Which is the same folder for .net 4.0,
So when you install the 4.5 it will cover the 4.0 version.
That the problem, when you unstall it, the .net 4.0 can't restore. So I suggest you clean the folder in v4.0.30319
Then reintall the .NET 4.0 that would be ok.

Thanks for the response, that's what I ended up doing. There were other issues as well. The Server Explorer no longer worked for viewing data or editing database schema. I had to replace a shared dependency that VS11 had installed over top of the VS2010
