[MonoDevelop] Problem debugging monodevelop 2.8 on windows with .net 4 runtime

Sun Mar 4 00:57:07 UTC 2012

Guys

I am new to monodevelop and have a problem on the 2.8 version on windows where it appears to be loading the .Net 2 runtime instead of the new .Net 4 runtime.  I have a test project and have set the default runtime in Tools-->options-->preferences-->runtimes to Microsoft .Net, and set at project level the default under BUILD-->General-->Target Framework to 'Mono / .Net 4.0).

I have the .Net FW 4.0 installed, along with  the windows SDK 7 for .Net, and the other pre-requisits for Monodevelp.  I had .Net 2 of the FW installed, and have installed version 4.0 of the .Net FW.  Never installed 3 or 3.5 as I think .Net 4 is standalone.

My solution runs ok however when I debug/F5  I get the following:

 Could not load file or assembly 'TestMono' or one of its 
dependencies. This assembly is built by a runtime newer than the 
currently loaded runtime and cannot be loaded. 

             Description: An unhandled exception occurred during 
the execution of the current web request. Please review the stack trace 
for more information about the error and where it originated in the 
code.

             Exception Details: System.BadImageFormatException: 
Could not load file or assembly 'TestMono' or one of its dependencies. 
This assembly is built by a runtime newer than the currently loaded 
runtime and cannot be loaded.

            Source Error:

            Assembly Load Trace: The following information can be helpful to determine why the assembly 'TestMono' could not be loaded.

It appears that it is trying to load the .Net 2 runtime instead of the .Net 4.0 runtime.  Do you have any ideas why this would be?

The output window contains the following:
