Hello, I have the followong exception, during requesting a webservice.

Requested URL: https://www.some_site.com/Services/Logout.asmx/js
Exception Message: Specified argument was out of the range of valid values.
Parameter name: utcDate
Exception Details: System.ArgumentOutOfRangeException: Specified argument was out of the range of valid values.
Parameter name: utcDate
   at System.Web.HttpCachePolicy.UtcSetLastModified(DateTime utcDate)

Thread: IsImpersonating = False

As I investigated, the problem originates because utcDate in method UtcSetLastModified is the date in future. This happens because the time zone on our side differs from the server's time zone where we deploy our application.

Please, HELP!

Thanks for letting us know about this problem!  This looks like a valid bug.

How are you deploying your app?  Am I correct in guessing you are using the "Publish web site" feature of VS or the "aspnet_compiler"?  If not, can you please let me know how you deploy it?

Do you mean that the time zone is different on the computer where you built your app and the server where you deploy?

Until we fix the bug, one workaround I can think of is to "touch" the precompiled dlls in our app's bin directory to update the last modfied time on them.

We build our application using MSBuild on local TFS (one time zone), and then just copy all builded dll's and other files to production server (it is in another time zone).

Another workaround i've found is to set in ScriptManager->ServiceRefrence InlineScript property to true, then all js for my web service will be included in the output page, so there's no need to request https://www.some_site.com/Services/Logout.asmx/js
