I am giving a talk on Web Services this week and one technology I discuss in virtually every Web Services talk is the Web Services Enhancement (WSE) Toolkit. One of the nice things about the WSE Toolkit is that it integrates with Visual Studio .NET - right-click on the Web Service or client project and there's a WSE 2.0 Settings option in the context menu that brings up a GUI to edit the WSE-related settings. However, in running through the talk/demo code today, I noticed that my copy of VS.NET on my laptop wasn't displaying the option in the GUI.
My first attempt at fixing this was to simply uninstall and reinstall the WSE Toolkit. Upon restarting VS.NET after this process, I got a dialog box with the warning, “The Following Add-Ins Failed to Load - WSE 2.0.” Urg. I did a bit of searching and discovered that one way to fix this was to “repair” the VS.NET installation. So, off I went to the Add/Remove New Programs screen and went to the VS.NET installation screen and clicked on the Repair/Reinstall option. This prompted me for the VS.NET CDs and, about 20 minutes later, wrapped up doing whatever in the world it was doing.
Fortunately, this fixed the problem for me. I have no idea what the problem was, exactly, but opting to repair VS.NET is what ended up working for me. Hope this helps someone else in a similar situation. For those more familiar with VS.NET Add-In specifics, any guesses/ideas as to what the problem was and, perhaps, a more direct, quicker workaround?
