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" />

You can load the project file to manually fix this.
