The Messaging Engine failed to create the receive adapter « WCF-SQL ».

In deployment scenario, I met this error :

The Messaging Engine failed to create the receive adapter « WCF-SQL ».
InboundAssemblyPath: « NULL »

InboundTypeName: « Microsoft.Adapters.Sql.BizTalk.WcfBtsSqlReceiver, Microsoft.Adapters.Sql.BizTalk, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35 »
