Selecting version of .NET Framework in VS .NET

[Teeravee Sirinapasawasdee]

How can we select between .NET Framework 1.0 and .NET Framework 1.1 in
Visual Studio .NET if we install both of them?

select between .NET Framework 1.0 and 1.1 in Visual Studio

This is only possible with VS.NET 2003.

VS.NET 2002 is like 'hard-wired' to the 1.0 Framework.

You have to update to VS.NET 2003 to build for the 1.1 Fx:

"Order Now", for ~29$+ :

Then you can select the target Fx like:

and VS.NET 2003 automatically generates a .config file for you.

Sure, you have to check for compatibility:
