  • Hi ,

    Have you refer the MSDN link https://msdn.microsoft.com/en-us/library/bb798087.aspx 

    to register the Echo Adapter . There maybe some assembly name mismatch or tag not well formed .

    Thanks

    Abhishek

  • Hi,

    Please try to install WCF LOB ASDK SP1, it should resolve your issue.

    I would suggest please refer below related thread for more help,

  • Hi - some things to try:

    1) Check that you have updated both the 32-bit and 64-bit machine.config.

    2) Check that you have installed the echoAdapterV2 in the host servers GAC.

    3) Check that the assembly details are correct e.g. that the assembly version number is 1.0.0.0.

    4) Once setup, close down the BizTalk admin console and reopen.

    5) A long shot but you have a space at the very end of the closing tag before the /> - try deleting this.
