C# – Adding a controller with read/write actions and views, using Entity Framework – what is “Data Context class”

This issue can occur when the Context is not correctly chosen from the dropdown. The context should be the value stored in the web.config

<add name="NamedEntitiesCs1"

that also contains the Model you want to generate.

You might find some of what you're looking for in Steve Sanderson's MvcScaffolding package

Nuget

Install-Package MvcScaffolding

After installing (it will probably install some EF requirements) you could scaffold basic CRUD views for your model as follows assuming a model type MySweetModel

Scaffold Views MySweetModel

Please note this command will not create the controller class, but should create the following views under /Views/MySweetModel

• _CreateOrEdit.cshtml
• Create.cshtml
• Delete.cshtml
• Details.cshtml
• Edit.cshtml
• Index.cshtml

It looks like you might be able to override the default T4 templates, but I've never used MvcScaffolding outside the scope of EF. It's also possible someone has already done this for your persistence layer e.g. NHibernate or whatever you're using. I'd search a bit before implementing your own templates.
