Can I (and how do I) target .net 4 with vs 2008?

VS2010 beta 2 is sloowwww on my machine. I'd like to start playing with .net 4 though. Can my vs 2开发者_Python百科008 solution's target .net 4 beta 2? How?

No you can't you need at least visual studio 2010 to target .net 4.0

No, you can't target .NET 4.0 using VS 2008.

To speed up, you can try to create this key in Registry (worked for me):

[HKEY_CURRENT_USER\Software\Microsoft\Avalon.Graphics]
"DisableHWAcceleration"=dword:00000001
