MakeSfxCA.exe and DLL compiled with Framework 4.0

I have a dll file compiled with Microsoft .NET Framework 4.0

When I am using MakeSfxCA.exe file and passing the dll as one of the parameter to command line it gives me following error message:

Any help is appreciated.

Thanks in advance.

My issue was slightly different, but it may be useful to other folks. The .config file has to have the name "CustomAction.config" in your project. It cannot have the name <YourCAProject>.config as will happen when you rename the project to give the dll a unique name. It seems the MakeSfxCA build tool and SfxCA stub depend upon this file name for now.

I got a similar issue working by adding the following code to the CustomActions.config file and creating a MakeSfxCA.exe.config file next to the MakeSfxCA.exe

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <startup useLegacyV2RuntimeActivationPolicy="true">
        <supportedRuntime version="v4.0" />
    </startup>
</configuration>
