Hello all ,

I know my page get error when test run with MTM but don't get error when run with Visual studio 2010.

the error is :

  Sys.WebForms.PageRequestManagerServerErrorException: Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that <machineKey> configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster.

thanks for your attention

Hi Aziz,

Thank you for your post.

I notice that you post two cases with same error message in recent days, are they belong to the same issue? If yes, please let me know that, i'll merge them for this will be very beneficial for other community members having the similar questions.

The another case is http://social.msdn.microsoft.com/Forums/en-US/vsmantest/thread/85721236-db6d-4ac0-b1bb-f2882c0a741d.

Hi Dear Lily,

I found solution, your link is my thread again.

I add a machinKey tag to my Web.conf of project and change default auto generate values.

I add this tag to my project

<machineKey
    validationKey="32E35872597989D14CC1D5D9F5B1E94238D0EE32CF10AA2D2059533DF6035F4F"
    decryptionKey="B179091DBB2389B996A526DE8BCD7ACFDBCAB04EF1D085481C61496F693DF5F4"
    validation="SHA1"
