Can I run scripts using LegacyV2RuntimeActivationPolicy?

I have a DLL (Microsoft.SqlServer.BatchParser) that I need to reference in my scriptcs file.

The following DLL can only be listed if useLegacyV2RuntimeActivationPolicy is included in the app.config file.

For example, this is a console application:

namespace ConsoleApplication
{
    class Program
    {
        static void Main(string[] args)
        {
            var batchParser = new ManagedBatchParser.Parser();
        }
    }
}

      

        
        
        
      

    

will only compile if I have included useLegacyV2RuntimeActivationPolicy in app.config like so:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <startup useLegacyV2RuntimeActivationPolicy="true">    
  <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5"/></startup>
</configuration>

      

        
        
        
      

    

But to do the same in the CSX file:

#r "Microsoft.Sqlserver.BatchParser"

var batchParser = new ManagedBatchParser.Parser();  

      

        
        
        
      

    

will fail because I don't know how to specify this attribute. I get the infamous error as soon as I try to run the scriptcs file:

Additional Information: The mixed mode assembly is built against runtime version 'v2.0.50727' and cannot be loaded into the 4.0 runtime without additional configuration information.

So my main question is, how can I tell scripts to start compiling the CSX file using the useLegacyV2RuntimeActivationPolicy attribute?
