can .net framework 4 works on top of windows xp?

问题

I tried to run a small application that I've written using VS2010 on my old Windows XP desktop. I got the yellow screen of death showing me a portion of the web.config with assemblies.

<compilation debug="true" targetFramework="4.0">

It looks like it didn't like the 4.0 framework. I re-wrote it, targeting 3.5 framework, this time it worked perfectly.

I'd like to know if I can install .net framework 4.0 on top of Windows XP?

Thanks for helping

回答1:

The system requirements indicate that Windows XP is supported as long as you have SP3 installed.

回答2:

Yes, that's possible. .NET 4.0 works fine on Windows XP machines. Just make sure SP3 is installed first.

回答3:

Yes you can :) Just download it and install

See MSDN, you need WinXP SP3
