Now. The EDMX (TT transform, custom tool, whatever, etc.) is generating BOTH DbContext classes (under the Model.tt/Model.Context.tt files) and ObjectContext classes (via the Model.designer.cs file). See image below:
Everything builds fine and works with the DbContext (but obviously only if I delete the Designer.cs file just before building) but the Designer.cs - and its ObjectContext-based code - keeps reappearing. How do I stop this behavior?!

I think the issue is having an EntityModelCodeGenerator
value in the Custom Tool
field of the .edmx
file properties. Just delete that value.
I think this is it, because I notice that in the project that I started off as an EF6 project, there is no value and it has no .designer.cs
file, but in the two that I upgraded from EF4, they both have the value and the designer file.
(This equates to a <Generator>
tag in the underlying .csproj
file.)

On normal EF Code First projects, Code Generation Strategy is "None" and ObjectContext is not generated.
It appears in your case that you Code Generation Strategy set to "Default".
To stop generating ObjectContext in xxxx.Designer.cs
, go to your edmx file, and change your Code Generation Strategy from "Default" to "None".
If you inspect xxxx.Designer.cs
// Default code generation is disabled for model 'C:\Users\xyxy\xyxyxy.Web\Models\xyxy.edmx'.
// To enable default code generation, change the value of the 'Code Generation Strategy' designer
// property to an alternate value. This property is available in the Properties Window when the model is
// open in the designer.

The .tt
files will generate the code regardless of the code generation strategy in the .edmx
. They listen to the .edmx
file changes. At least this is how they are working for me.
So by turning the code generation strategy to None
in the .edmx
you make the .designer.cs
file empty of any useful content.
Then open up the project file, find the nodes representing the .edmx
, by default it is contained in EntityDeploy
node ie the Build Action value, and remove its Generator
subkey.

I didn't find out how to stop the Designer.cs file from generating the ObjectContext, but I did figure out how to make it so that it doesn't matter. Just set the Build Action to "None" instead of "Compile".
