Looking for something?

Since I’ve been a bit on the lazy side when it comes to the blog (due to multiple reasons..), I’m thinking about writing up an article-series where I’ll talk about .NET 3.5 and what it has to offer when used in conjunction with SharePoint. Any input is welcome, of course :)


In this article I will try to get you up and running with the .NET 3.5 framework in your SharePoint environment, just like I’ve previously described how you can get AJAX and Silverlight 2.0 up and running:

I will now let .NET 3.5 be a part of some of my upcoming SharePoint projects, and because of that I thought it could be a good thing to blog about it if there’s anyone out there looking to do the same!

Prerequisites before we get started

In order to follow along, I assume the following few bulletpoints are in place:

  • Microsoft .NET 3.5 Framework is installed on the front-end server
  • You already have got a Web Application on which you want to do these changes

Add support for .NET 3.5 in SharePoint (WSS 3.0 or MOSS 2007 alike)

Here you will find a manual step by step instruction on what web.config values to set in order for .NET 3.5 to work properly with your SharePoint installation.

Note: I’ve added some linebreaks in order for the text to show up properly in my blog, you may remove them if you want your web.config to be pretty ;)

Note2: All additions to any elements in the web.config file should be added at the bottom/end of each element unless excplicitly stated otherwise.

1) Add the following snippet inside the ** element
2) Add the following snippet inside the ** element
3) Add the following snippet inside the ** element
4) Add the following snippet inside the ** element
5) Add the following snippet inside the ** element
6) Add the following snippet inside the ** element
7) Add the following snippet inside the ** element
8) You’re done

When you’ve added the needed tags, you’re all set – you can now run your .NET 3.5 applications inside SharePoint (of course, this applies to the web application where you just added these settings.

To see that your site still works, do the following:

  • Launch your site where you’ve made the changes!
  • Cross your fingers

Cool, what’s next?

Well, if you’ve managed to get your site up and running – you can now create webparts, features, controls or whatever you’d like to create and have them published to your site.

This article describes how you do these things manually, but what if you want to do these things automatically somehow? Is that possible?
– Yes, but that’s going to be covered in an upcoming blogpost
