Evaluation Period has Expired

Dear All,

I am trying to run a simple C# query in LINQ and the following error comes up in the result pane :InvalidOperationException: The evaluation period for Microsoft StreamInsight instance 'isntancetemp' has expired. For information on how to upgrade your evaluation software please contact Microsoft.
Does anybody know what that message mean or what i have to do to fix this?



  • I take it you're trying to query a StreamInsight source? If not, click the 'Connection' combo above the query and change it back to 'None'.

    If you are querying StreamInsight, I take you've purchased a StreamInsight license?

    If you're unable to purchase a license, take a look at Reactive Extensions. It does a similar kind of thing and is free. LINQPad extensively supports both StreamInsight and Reactive Extensions.
  • thank you very much. It is pretty silly of me that i never tried 'None'. My problem is now solved
