Buiding MVC3 solution went well but have got an error in browser:
Compiler Error Message: CS0234: The type or namespace name 'Html' does not exist in the namespace 'System.Web.Mvc' (are you missing an assembly reference?)
Source Error: Line 25: <add namespace="System.Web.Mvc" /> Line 26: <!--<add namespace="System.Web.Mvc.Ajax" />--> Line 27: <add namespace="System.Web.Mvc.Html" /> Line 28: <add namespace="System.Web.Routing" /> Line 29: <add namespace="System.Web.WebPages" />I have installed packets for the solution with NuGet and set up for all projects MVC3. Does MVC3 include libraries System.Web.Mvc.Ajax, System.Web.Mvc.Html and others? Why am I getting the error?
In References folder, I have System.Web.Mvc

Clean your solution and then set the property of those files to Copy Local = True.
To set the Copy Local property to True or False
In Solution Explorer, click the Show All Files button to display the References node.
- Open the References node for the project.
- Right-click a reference in the References list, and click Properties. The properties associated with that reference appear in a list in the Properties window.
- In the Properties window, change the Copy Local property to True or False.
