machinekey validatekey isolateapps not working with framework 4.6 RRS feed

  • Question

  • With machinekey validatekey isolateApps it is working fine with framework version 4.0 but not working with 4.6

    Here when I remove isolateApps at end of validationKey thet it is working with 4.6

    Below is example machine key.

    <machineKey decryption="DES" decryptionKey="{hex-key value},IsolateApps" 
        validationKey="{hex-key value},IsolateApps" />;

    Please suggest what goes wrong.


    I found these stuff in Internet:

    https://stackoverflow.com/questions/36714647/why-would-adding-targetframework-4-5-to-httpruntime-in-web-config-make-my-decr


    here it is written "After looking further it appears it is the ,IsolateApps that is the issue. Before targetFramework was added, IsolateApps was fine in the machineKey, but with 4.5 added it is seen as no longer valid."

    Please suggest correct behavior of IsolateApps with framework 4.6
