MVC 3 Scaffolding Error when running Scaffold Controller

I have installed MvcScaffolding without any issues but when I try to execute a scaffold request I get the error "DbContext.Task.t4" does not exist along with other files that are missing. I have a model called Task which I think its referring to but I am at a loss on how I fix this error?

"Scaffold Controller Task -ModelType Task -ControllerName TasksController -DbContextType TasksDbContext"

Install-Package MvcScaffolding

  • PM> Install-Package MvcScaffolding
  • Attempting to resolve dependency 'T4Scaffolding (≥ 1.0.2)'.
  • Attempting to resolve dependency 'EntityFramework (≥ 4.1.10311.0)'.
  • Successfully installed 'MvcScaffolding 1.0.2'.
  • Successfully added 'MvcScaffolding 1.0.2' to MvcApplication1.

Error

  • PM> Scaffold Controller Task -ModelType Task -ControllerName TasksController -DbContextType TasksDbContext

ANSWER It turns out that my model's namespace needs to be the same as the MVC project. Once I changed the namespace the scaffolding worked.

I had this same issue, but it was due to the model classes having errors in them, which caused them to not build. Thus there was no model matching the name I gave to scaffolding and it concluded that I hadn't used the correct namespace.

So...

  • Check your code for build errors
  • Make sure the namespace of your Models is the namespace of your Application
