Usually I develop on a CRM server but sometimes, when a larger piece of CRM-independent part needs to be developed, I develop on my local machine.
Presently I am working in an integration project with an integration engine and needed to consume one of it's webservices. I did so and I added some code to handle it (intellisense working fine) but when I tried to run it, it crashed on the constructor or the service class with the following error:
System.IO.FileNotFoundException: File or assembly name gvy6umsk.dll, or one
of its dependencies, was not found.
There was also a reference to the Windows\Temp-directory. The filename is obviously some temporary filename for the proxy-object.
After checking the web a bit, I found the error to be caused by the fact that the user running the software, did not have read/write access to the c:\windows\temp directory. I fixed it and the program ran like it should!
So, if you are in the same situation, just fix the right for the windows\temp directory and you should be fine.
