I recently uninstalled the January CTP of WinFX and then installed the February CTP (see instructions here). I have been moving right along with no problems until late last week when I tried to “Add Web Reference...” When I did, I received this peculiar dialog that said “Some of the files required for Web references are not installed.”
Apparently, somewhere in the uninstall/reinstall process the wsdl.xsl file in C:\Program Files\Microsoft Visual Studio 8\Common7\Packages\1033 disappeared. The solution, for now, is to get a copy of wsdl.xsl and put it in the directory. For me that was easy because I have multiple machines with Visual Studio 2005 installed. I suspect many of you don’t have that option so I asked if it was ok to post the file. I have attached the file to this post.
