Can I develop Web Parts for MOSS 2007 with .NET 3.5?

Currently I am developing Web Parts for MOSS 2007 using .NET 2.0 and deploying them to the GAC with WSPBuilder. I would like to move to .NET 3.5 to open up things like LINQ and WCF.

Is this possible and will there be any significant changes开发者_JAVA技巧 required to MOSS to support doing so?

I haven't done it myself but Tobias Zimmergren posted a guide on his blog: http://www.zimmergren.net/archive/2008/09/22/how-to-get-up-and-running-with-net-3-5-in-your-sharepoint-environment.aspx

Yes. I do it all the time.

Just make sure the target machine has .NET 3.5 and you're "good-to-go". (The same run-time can host .NET2-3.5 as they use the same underlying "engine".)
