Could not load EnterpriseLibrary assemblies when rendering view in MVC application - asp.net-mvc

Question

When rendering a view in an ASP.NET MVC application, I am getting the following Yellow Screen of Death. It will occur only once during the server lifecycle, subsequent renders work fine. I don't have any references to EnterpriseLibrary 4.0.0.0 within the application itself, which makes me think that the reference is outside of my application (machine.config or something similar). I have checked for EnterpriseLibrary references in C:\Windows\Microsoft.NET\Framework\v4.0.30319\config\machine.config and C:\Windows\Microsoft.NET\Framework64\v4.0.30319\config\machine.config but neither had any reference. Any ideas?
Thanks in advance.
EDIT: The error is occurring on the following line:
< asp:ScriptManager ID="ScriptManager2" EnablePartialRendering="false" runat="server" / >
., it previously appeared the error was occurring on the call to Telerik.
EDIT2: I can fix the error by removing < asp:ScriptManager ID="ScriptManager2" EnablePartialRendering="false" runat="server" /> which further points towards this being the problem. I am unsure as to why it is happening, however, and cannot claim I have an answer to the problem.
Here is the YSOD:

ASP.NET MVC does not support the ScriptManager object. This makes sense as the ScriptManager is a Web Forms element and does not fall into the MVC world. As to why IIS attempts to load unreferenced assemblies when the ScriptManager bombs, I still do not know. It seems to load whatever is in the BIN directory (I had left over EntLib 4.0 assemblies in BIN) but then continues to load beyond this. I stopped trying to get to the bottom of where it was loading from when IIS returned "Could not load file or assembly DeployLX.Licensing.v4." I fixed by removing all ScriptManager references from the MVC application, as they were not required anyhow. If I was to use them there is a MVC ScriptManager available http://mvcscriptmanager.codeplex.com/
tl;dr; MVC does not support ScriptManager. I removed it.
