The view 'Index' or its master was not found.

The view 'Index' or its master was not found.

方案1

Global.asax file contain the URL Route. Default URL route like this.

"{controller}/{action}/{id}"

So,Try this.

1. Right click your controller method as below.

Example: let say we call Index() method.Right click on it.

2. Click Add View.. and give appropriate name.In this example name should be Index.

Then it will add correct View by creating with relevant folder structure.

方案2

This error was raised because your Controller method name is not same as the View's name.

If you right click on your controller method and select Go To View (Ctrl+M,Ctrl+G), it will either open a View (success) or complain that it couldn't find one (what you're seeing).

1. Corresponding Controllers and View folders name have the same names.
2. Corresponding Controller methods & Views pages should same have the same names.
3. If your method name is different than view name, return view("viewName") in the method.
