You have access to code generation when running MDriven in Visual Studio.

If you open the model from within Visual Studio and it loads as XML instead of as a model surface, this is probably one of two possible problems:

1. You have not installed the MDriven Framework for the correct version of Visual Studio
2. Your ecomdl file has been tagged by VS to open in the XML designer. If this is the case, the project file looks like this on the node for the ecomdl file:

<None Include="yourmodel.ecomdl">    

<SubType>Designer</SubType> 

</None>  

When in fact, it should look like this:

<None Include="yourmodel.ecomdl" />

Load the project file to manually fix this.
