In this post I’ll explain how to handle work item create/update requests from WebAccess.


What’s in the request again ?


Last time we figured out what Visual Studio requests to TFS in order to create/update Work Items. With this information, we’ve created a simple validator which prevents a specific user from creating work items. It may work wonders when the request is being sent to the ClientService.asmx service as VS does, but unfortunately this kind of operation is not centralized, so if you try to create the work item through WebAccess, your validation just won’t work.

Keeping that in mind, we’re going to inspect WebAccess to figure out how does it creates/updates work items. It’s actually easier than before because we can see the request in the browser itself: Click here to read more.

In this post I’ll explain how to intercept a work item creation request and prevent the operation from executing.


What’s in the request ?


After creating a simple plugin using an ITeamFoundationRequestFilter implementation, you are now able to intercept requests to TFS.

I recommend using a software such as Fiddler to capture requests and observe what they’re like. In our case, we’re going to investigate what goes on when we create a WorkItem on Visual Studio and on Web Access. I’ll also be using Fiddler since it’s well known and easy to use.

How this came up – The problem with Work Item Process Editor 


If you’ve worked a fair time with TFS you know it surely has its pitfalls and issues. One thing that upset me a lot before is validating work items. You never know what kinds of requirements people can come up with, and with such a limited interface there isn’t much you can do. Click here to read more.
