[Solved] Telerik is not a memeber of system.web.mvc.htmlhelper

[Alan Mosley]

i know that telerik mvc controls are not supoted on mvc4 yet, but i added them using nuget to a MVC4 project i have and all worked well. I then decided to add them to anouther MVC4 project and this time it did not work
I can get a ref to telerik.web.mvc, but not to HTML.telerik, i get the "Telerik is not a memeber of system.web.mvc.htmlhelper" error.

I have had a look at both projects side by side to try and work out why it works in one and not the other, yet i can find nothing, all versions seem the same everything. yet still have the problem.

Whats should i be looking for that would stop me getting a ref to HTML.Telerik ?

Any help would be great, thanks

I have found out a little bit more info to this problem.
If i create a MVC4 project and add MVCextentions from nuget, all works fineBut when i add a existing class lib to the solution reference HTML.Telerik is lost.

Anyone does this shine some light on the problem, can anyone point mein the right direction?

OK solved it, the class lib, had a ref to mvc 3 in it, why i dont know, anyhow removing it fixed the problem
