I was trying to update a service reference in a Silverlight project and  I got :  Error HRESULT E_FAIL has been returned from a call to a COM component.

Problem was that ServiceReferences.ClientConfig file being actually a common file shared between 3 projects, I extracted it outside and referenced it from a common project as a link to the file. When the reference (creation or update) wizard is trying to update this file, this "very descriptive and intuitive" error shows up.

So, when getting this error and in doubt check that configuration file is writable from your location.

Good luck!
