Mixed mode assembly errors after upgrade to .NET 4 Beta 2
I began receiving this error after upgrading to .NET Beta 2 …
System.IO.FileLoadException: 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 suspect it’s the Managed.DirectX DLL that I’m using.
Adding the following to the application config file appears to have solved the problem for now:-
<configuration> <startup useLegacyV2RuntimeActivationPolicy="true"\> <supportedRuntime version="v4.0"\> </startup> </configuration>
