Trying to target ASP.NET 2.0 in Visual Studio 2010

al-w-b used Ask the Experts™
My present application is in limbo....  It works great in IIS 5.5 targeted for .NET 4.0.  It does not work in IIS 7 targeted for .NET 4.0.

So to keep things safe I need to target it in ASP.NET 2.0, which should work.  It is an old stable application, but when I installed Visual Studio 2010 in configured the app for .NET 4.0.  I get numerous errors when I try to rollback to 2.0.

For starters... in Visual Studio 2010, under the website properties tab... the Target Framework drop down only lets me select ASP.NET 4.0... I can't change it to 2.0 here, so I guess I have to do it by hand.

My web config is below.  The errors I get in the 2.0 environment revolve around the ScriptManger.  However, I have the AJAX library in the bin and I am only using UpdatePanels and UpdateProgress panels in a very simple way.  It all used to work in the 2.0 environment before visual studio 2010 changed my web.config.

*note: In the code below I did not expose sensitive data.  IF you see something like [This works] it means that the value of that particular node has been tested and works in both IIS 7.0 and IIS 2.0.  

Based on this web.config file which direction would it be easier to take the app... ASP.NET 2.0 on IIS 6.0 or ASP.NET 4.0 on IIS 7.0?

What changes do I have to make to this web.config file to make it work in ASP.NET 2.0 again?

How can I add ASP.NET 2.0 to the Visual Studio 2010 Target Framework Drop Down list?
