Looks like you are using older version that doesn't have the webapi controllers , but that's only used for some v7 related stuff so removing that assembly makes it work :)
basically sometimes it will work fine other times it will show up
could not load type 'System.Runtime.CompilerServices.ExtensionAttribute' from assembly 'mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.
relating to <asp:ScriptManager ID="ScriptManager1" runat="server" />
But its also caused an XSLT macro to start erroring, in the stack trace its showing:
umbracoMacro InnerException Could not load type 'System.Runtime.CompilerServices.ExtensionAttribute' from assembly 'mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.
I tried downgrading to v3.0.17 which fixed the error with the macro, but my Contour forms then stopped working.
A quick google shows that error is something to do with .net 4.5.
Upgrading Contour Isssue
Hey,
Ive updated contour like it says on the upgrade steps from Contour 1.1.12 to 3.0.18.
However i am now getting
Could not load type 'Umbraco.Web.WebApi.UmbracoApiController' from assembly 'umbraco, Version=1.0.4807.33359, Culture=neutral, PublicKeyToken=null'.
Server error on any page i go to.
Any ideas why this might be happening, i tried reverting back my files and installing 3.0.6 which was greeted with the same issue.
Thanks in advance. Im using Umbraco 4.11.5 which has been upgraded from an earlier v4.x version.

Could you remove the v7 providers assembly and see if that fixes anything
Yeah that appears to have fixed it. Thanks Tim

Yeah make sure you have .net framework 4.5
Just had the exact same issue, removing the v7 providers assembly fixed the issue.
Thanks both
