    Based upon your partial message it looks like a type in an old assembly was moved to a new assembly. In the old assembly there is a type forwarding attribute so the CLR goes to the new assembly to load it. However your code isn't referencing the new assembly and therefore it fails. You need to add a reference to System.Data in the impacted code.

  • Hi,

    >>"the type 'system.data.Common.DbConnection' has been forwarded to an assembly that is not referenced.Consider adding a reference to assembly 'System.Data, version 4.0.0.0..."

    You should add the reference to this assembly using the Reference tab. Right click Reference, select Add Reference and then (in the new window that opens up for you) select the assembly that is required; in your case System.Data with version of 4.0.0.0. (Make sure this is present on your system installed)

    Then you should (first) clean the project, then re-build the project with the new resources and assemblies in the project.

    Regards,

    Frankie
