A couple of days ago I installed the Web Services Enhancements 3.0. To get a first overview, I wanted to play a bit with the WSE 3.0 Hands on Labs. But I got stopped pretty soon, as I discovered that there was no WSE add-in registered within my Visual Studio 2005.

After digging through websites, forums and newsgroups in order to solve the problem, I found the solution myself.

So, if the WSE 3.0 settings context menu in your solution explorer is missing after installing WSE 3.0, try the following:

Locate the file WSESettingsVS3.Addin. I found it at C:\Documents and Settings\All Users\Application Data\Microsoft\MSEnvShared\Addins\. Just copy this file to a folder that is registered as an Add-in folder within VS. For example to C:\Documents and Settings\<User Name>\My Documents\Visual Studio 2005\Addins\.

This should do the trick.
