Biztalk 2016 - Random Assembly Loading Error RRS feed

  • Question

  • We have deployed our solution ,after Migrating from Biztalk 2013 R2 to Biztalk 2016.

    We upgrade the code (.net framework etc) through Visual studio , compiled the new solution and deployed it.

    During testing , we are observing ServiceActivationException for Orchestrations. Randomly.

    The error says : "Loading this assembly would produce a different grant set from other instances." A host instance restart fixes this issue temporarily , only to return. 

    Unable to find the cause of this error yet. 

    Any help will be much appreciated. Thanks in advance.

  • As per this thread, try GACing or redeploying the DLLs again and restart all the host instances and maybe a IISReset if you have anything running on the Isolated Hosts.
