In the version 1.0 of WCFStorm, there was a bug that occasionally causes WCFStorm to crash when ran in a 64-bit OS. The previous fix was to replace the System.Data.SQLite.dll with the 64-bit version but that didn't work all the time.
Now in version 1.1, we are please to announce that the bug has been fixed and WCFStorm now works out of the box in a 64-bit OS.
