    I'm trying to upgrade a site from 3.7 SP3 to SP4 so that then we can upgrade it the latest version. I've overwritten the original files with the files from the patch, but when I try to build the solution in Visual Studio, I get the error "Unrecognized configuration section system.web.extensions." 

    It looks like it could be related to still having references to framework 2.0 in the project, or having the app pool in IIS not set to framework 4.0. But the app pool is set to framework 4.0 and I can't find anything in my project that is referencing framework 2.0.

    Any suggestions?

    Hi Elizabeth,

    The exception you are getting is usually due to the fact that the <system.web.extentions> tag is not applied to your web.config file. Further information can be found here.

    Please go through this KB article and make sure you have configured your solution to point to the .Net 4.0 framework.

    The app pool is set to .Net Framework v4.0.30319 and it is a web site project so there isn't a .csproj file. Where else could I look for references to the wrong framework? The web.config is based on the web.config that came with the SP4 patch - I just updated items like the connection string.

     Where can I find info about new assemblies for 3.7 SP4?

    Hello Elizabeth,

    This is indeed strange. It sounds like you have made all the necessary configurations. What I can suggest is creating a new 3.7 Sitefinity project and compare its configurations to the ones you have in your site. Provided that does not solve the issue you can send us a support ticket where the support team can investigate this in further depth and request your solution in necessary.
