Hi Nathan,

I recommend you upgrade the servers promptly to support 2.0, but I
understand if you don't have the authority.  Also, you say you upgraded to
2005 but Visual Studio .NET supports side-by-side installation.  If you
still have 2003 just use 2003.

VS.NET 2005 is converting the project files to the new format supported by
VS.NET 2005.  I don't think you can stop this process, however I don't
believe that it's changing any of your code.

Try building as you normally would to ensure that you haven't used any
breaking changes from 1.1 to 2.0.  If it builds you can use an app.config
file to redirect the framework version that your program uses from the 2.0
assemblies to the 1.1 assemblies.  I have not tested this method.

Just open the *file* that you want to edit, rather than the
solution/project.

The easiest way is to select the Visual Studio project in Explorer, right
click, select "Open With" from the popup menu, then select "Microsoft Visual
Studio 2003" from the submenu.  This will open the project in VS 2003.  Then
in the future, you can simply double-click on the project, as the Visual
Studio Project Selector will know that you want to edit this project in VS
2003.  (If you rename or move the file, you will have to repeat the process.)
