Coverage hangs in the ‘Initializing external storage’ state


Coverage hangs for several minutes in the Initializing external storage state, then the “Failed to initialise external storage...” error is shown.


Possible cause

There is a WCF service running in the operating system that blocks other net.pipe WCF services (including dotCover). An example of such a service is a part of the HP Support software: HPSupportSolutionsFrameworkService.exe.



Disable blocking WCF services:

  1. Download the handle.exe tool from
  2. Run the tool as administrator:
    Handle.exe net.pipe:
  3. The tool will show you the list of blocking services.

Disable the found services.
