There was a failure executing the receive pipeline document specification from assembly failed to load

错误：

There was a failure executing the receive pipeline: "Microsoft.BizTalk.DefaultPipelines.XMLReceive, Microsoft.BizTalk.DefaultPipelines, Version=3.0.1.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" Source: "XML disassembler" Receive Port: "ReceivePort1" URI: "SQL://TIMON-PC/UserInfo/01" Reason: The document specification from assembly failed to load. Verify the schema for this document specification is deployed and is in the Global Assembly Cache.

解决：

- if you redeploy an assembly you need to restart the Biztalk Host Instance. In this case the Biztalk Isolated Host Instance which is IIS - just use the iisreset command.
