Is there any issue installing .NET 4.0 on the same server that's running .NET 3.5.1/SQL Server 2008 R2?

Should not be an issue. .NET frameworks are backwards compatible. However, like SQL Server, some features may be removed moving forward. There were certain features in 1.1 and 2.0 that are no longer in 3.5+. If your application uses those, then you must have the particular version installed for it to work. However, installing a newer framework won't affect the existing application.

nope no issue at all;
they get installed in seperate directories, ie inside C:\Windows\Microsoft.NET\Framework64
you'll see V2.0.50727,v3.0,v3.5 and v4.0.30319

when you create a visual studio project, you can target which framework to use.

All versions of the .net framework can co-exist on the same server. You should be OK.
