Hi Hodge,

I had the exact same problem when I deployed an update of our
webservice on our development server. I did it like 50 times and it
worked every time, and now suddenly I got that freakin' exception.
But i solved it!

Good to know:
On our webserver we made a subdirectory in c:\Inetpub
(C:\Inetpub\Company), which is also a website in IIS, so not under
Default website. In that directory we deployed our webservices.

Solution:
I did 2 things:
1) I deleted all the subfolders of C:\Inetpub\Company which had hidden
cache folders and stuff
2) I ran the ASP.NET IIS Registration Tool (Aspnet_regiis.exe) for the
.NET 2.0 framework to re-registrate the .NET 2.0 framework in IIS. You
just run the tool in your command window:
C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Aspnet_regiis.exe -i

I don't know which part made it work again. It could be just one of
them or the both of them. All I know is that it worked for me and I'm
super happy!

Hope this helps you!

Kind regards,

xplain.
