  • Have you tried removing the reference to the DecompressionEnabled property?

  • I haven't seen that error before but try taking a look in your bindings that get generated in your configuration file. If there is a property called 'decompressionEnabled' try commenting it out and seeing if it helps.

  • I just got the same issue occurring.

    I migrated a 2008 project that includes WCF services to 2010 and tried to run it and got the same error.

    <Edit> On further investigation, it appears that this attribute was inserted when I re-created the service references within the UI project. And the DecompressionEnabled attribute is a .net 4 framework attribute. However I am targetting 3.5.

    Please help.

  • Yes, and this fixes the issue.

    But, everytime I update the service references, I have to remove the DecompressionEnabled property.

    I hope this is in the pipes to be fixed for SP1
