.NET Framework 3.0 "activation" ?


T

Hi all,

Having
Visual Studio 2005
.NET Framework 2.0
Windows XP SP2
I installed .NET Framework 3.0 ("dotnetfx3".exe - 50 MB). The
installation was successful, and if I go to Settings -> Control Panel
-> Add or remove programs, I can see the "MS .NET Framework 3.0".
However, when I open Visual Studio 2005, and show the "about", it
still says ".NET Framework 2.0.50727. Also, with the object browser, I
cannot see the new classes provided by .NET Framework 3.0 (like
System.Windows.Media.Visual). It's like I installed it but it is not
"activated". Have I missed any step? Is there any way to tell Visual
Studio 2005 to "use" the .NET Framework 3.0 installed instead of the
2.0?

Thank you

Did you also download and install this?

http://www.microsoft.com/downloads/...37-CC86-4BF5-AE44-F5A1E805680D&displaylang=en

That will add the the new 3.0 project types under the VB and C# categories.
As 3.0 just adds to 2.0 for the WPF project types, the other types will
continue to use 2.0.

Hi Tremendo,

Installing .Net 3.0 does not automatically enable the new features to VS 2005. You need to install the appropriate extensions for this. One extensions enable WF (Windows Workflow Foundation) and the other WCF and WPF (Windows Communications/Presentation Foundations).

http://msdn.microsoft.com/vstudio/devsolutions/

VS 2005 can't be set to use .Net 3.0 instead of .Net 2.0 as .Net 3.0 _IS_ .Net 2.0, but with added libraries. Installing .Net 3.0 on a computer without any .Net versions will install .Net 2.0 as well.

I have successfully installed framework 3.0 but when I try to install the Visual Studio 2005 extensions for .NET Framework 3.0 (WCF & WPF), it complains that I do not have visual studio 2005 installed. I do have VS2005 installed and have been using it for a while, however, in the control panel add/remove program, it's listed as Microsoft Visual Studio 2005 Team Edition for Software Architects. Is this the problem?
