After updating my code from Visual Studio 2005 to Visual Studio 2010 I am getting the error while compiling
"Mixed mode assembly is built against version 'v1.1.4322' of the runtime and cannot be loaded in the 4.0 runtime without additional configuration information"

I have tried making the change <startup useLegacyV2RuntimeActivationPolicy="true"> in the app.config, even then I keep running in to the error

Also, I need to generate the serialize assembly for this code so I have kept the "Generate serialization assembly: On".

Target Framework for the project is .NET 4.0

Any help on this..

Is this question in the right forum?

Do you have the source code for the DLL (dot net Assembly) that was built with 'v1.1.4322'? If so, can you re-compile THAT?

If you change your target dot net level to 3.5 or lower, does it work?
