Hello,

I've just installed Umbraco v7.5.12 from Nuget and developing my Umbraco site. I have a few packages installed too (see image packages.png).

When I right click on partial views in the Settings tab, I get an ASP.NET runtime error. Please see attached images. I created a folder called "Nav" in Visual Studio and then reloaded the node. I can see the folder but I can't create anything in Partial views.

The exact exception is:

Server Error in '/' Application.

Method not found: 'Void umbraco.editorControls.ResourceExtensions.RegisterEmbeddedClientResource(System.Web.UI.Page, System.Type, System.String, umbraco.cms.businesslogic.datatype.ClientDependencyType)'.

Version Information: Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.6.1085.0

What am I doing wrong? With previous versions, there was no problem creating one.

Please help.

Thanks.
