I have the same error. I am pretty conficed i have the right assembly in my project, but it keeps giving the exact same error as mentioned in the start of this topic.

For anyone else who reads for help about this error: how should we tackle this? Where are the assemblies located that the solution thinks are incorrect versioned?

Hi Frank,

Thanks for your update.

We suggest you to check the following.

1. Referenced assembly and web.config version are same.

2. There should be no dll in bin if referenced from GAC. Please clean solution before build.

3. Check whether there is conflict between MVC2 and MVC3. Please refer the below link

Note: To know more about the steps to switch between (Mvc2 to Mvc3) , please refer the document here :


Please let us know if you need further assistance.
