Could not find an Extension with ID

Asked By Larry G Coleman 0 points N/A Posted on - 03/08/2013

I installed MVC4 and attempted to develop my initial MVC4 (WebAPI) project. I did click on Create New Project; selected ASP.NET MVC 4 Web Application, and after that choose the WebAPI template. While I press the OK button, I received the below error message. Does anybody have an idea how to solve this? Need assistance Please.

Microsoft Visual Studio

Package Installation error

The project template has a reference to a missing extension. Could not find an Extension with ID

‘Microsoft.VisualStudioiO.MVC4.TemplatePackages-ENU'

OK

Dear Larry,

As you mentioned you installed MVC4 and also tried to Create a New Project by selecting ASP.NET MVC 4 Web Application but you couldn’t go further. The folders called "Asp.net MVC4 template packages" and NuGet Package Manager" are important to create a MVC4 project. Now I think some other MVC4 installed in the system and you only have a NuGet Package Manager folder which is the reason you have received the error message. So at first you need to have both the folder then you can create a new project.

I hope this will solve your problem.
