When you attempt to enable/disable a receive location that uses WCF-SQL adapter, or when you attempt to start/stop a send port using WCF-SQL adapter you may experience this error "Failed to create 'WCF-SQL' Transport Component".
Microsoft.BizTalk.ExplorerOM.BtsException: Failed to create 'WCF-SQL' Transport Component
at Microsoft.BizTalk.ExplorerOM.BtsCatalogExplorer.SaveChangesWithTransaction(Object transactionObj)
c8089c26347d4d0c5d5b248deacbe158a, ReceiveLocationOperation c5643bd14c28f75e668b81c80acad00)
at Kovai.BizTalk360.BusinessService.Main.BizTalkApplicationBusinessService.ChangeReceiveLocationStatus (ReceiveLocationCollection receiveLocations, ReceiveLocationOperation operation)
This error will occur more likely, when you have installed BizTalk360 on a stand-alone server. To resolve this issue, install the BizTalk enterprise adapter pack (in this case WCF-SQL) in the server where BizTalk360 is installed.
You will face similar issue for other enterprise adapters like WCF-Oracle. So, if you are using any of the enterprise adapters, please install them on the server where you have installed BizTalk360.
