warning CS0436: The type 'T4MVCHelpers' in ... conflicts with the imported type 'T4MVCHelpers' in ... Using the type defined in ...


This issue is similar to the issue that was once around with Extensions. It happens if you reference a DLL (project) that had T4MVC included and compiled.

Is it possible to introduce a setting which could prevent doubling the T4MVCHelpers static class?

Ok, I made that change. Available in T4MVC 3.4.1 on nuget.

Ah right, that's the one class that's still generated. I wonder if we could just make it internal, since I think those methods are only meant to be called from within the assembly itself.

Can you give that a try? Just change it in your

Tried it, generates T4MVC.cs with T4MVCHelpers internal but the same warning remains at compilation.

Right, it works if I change it to internal in the project that I am including. Previously, I only changed it in the project that was consuming the other project (both of which had T4MVC added via NuGet).

Right, it would need to be changed everywhere. Try to play around with that, and if everything seems good, maybe we can just make that change in T4MVC.

Seems to work fine and I don't see how it could go wrong if we change it. Each module that uses T4MVC essentially creates its own internal helpers. I think that's reasonable.
