.NET Framework support in SharePoint 2010

  • Artigo

There are recent customer questions about .NET Framework support in SharePoint. For example, there is this question in the SharePoint 2010 forums, as well as several customer questions at SharePoint booth at TechEd.

SharePoint 2010 does not support access from .NET Framework 4 or being run in a .NET Framework 4 app domain. If you must support the .NET Framework 4, we recommend that you develop a web service that uses the .NET Framework 4 and then connect to it from SharePoint. All server-side customizations directly for SharePoint 2010 still need to be either the .NET Framework 3.5 or the .NET Framework 3.5 SP1.

For more information, see the following MSDN Library topics.

 

However, you can use Silverlight 4 and Silverlight 5 against the SharePoint client object model. For more information, see the following MSDN Library topics.

    Hi How are you? I would like to know if it's recommended/supported or not to install .net framework 4.0 on a SPS 2010 production environment. I didn't find any information regarding to that. Thanks. Kind Regards.

    Hi Héctor, Yes, installing .NET Framework 4 on the same computer as SharePoint 2010 is supported. For example, if you install Visual Studio 2010 on a computer with SharePoint 2010 for development purposes, the .NET Framework 4 would co-exist with SharePoint 2010.

    We have a .NET web application developed using .NET 4.0. Our application was able to connect to earlier versions of SharePoint using the API, but has failed with SharePoint 2010 due to this restriction. We are unable to create a web services to connect to our app from SP - it is not feasible. Why would Microsoft implement such a restriction in SP 2010? Our application's feature has effectively been broken.  What workarounds or fixes do you have?

    SharePoint 2013 supports .Net 4.0 though right? That is the default on the application pools for SharePoint such as "Sharepoint Central Administration v4" as I see in in the list of Application Pools in IIS Manager.
