How to deploy Sitefinity site developed in 3.7 SP2, in IIS7 under 4.0 framework?
I have a website developed in Sitefinity 3.7 SP2, that is running successfully on server.
But when I try to run on local system, by Integrating the project in asp.net 4.0 environment. I get following Error:
first version of Sitefinity which support .NET Framework 4.0 was 3.7 Service Pack 4. In my opinion first thing to do is upgrade you project to Sitefinity 3.7 SP4.
As Pavol suggested, the 3.7 SP2 version is only for .NET 2.0, which may be in conflict when running the project on IIS 7 .NET 4.0. As suggested in the other forum threads, you can go ahead and apply a patch which will upgrade your 3.x site to SP4 .NET 3.5 / .NET 4.0. The following KB can help you find the proper version of Sitefinity 3.x you have ( and the .NET version ):
