Deploying Asp.Net to a different time zone, Temporal Future Shock! Specified argument was out of the range of valid values. Parameter name: utcDate

by Jon 17. December 2010 09:57

You would have never of thought it but if you compile ASP.NET in a different timezone you could cause yourself some temporal problems.  I recently discovered that parts of ASP.NET are date specific and if you compile an ASP.NET application in one timezone (The UK), and deploy to another timezone (California) you may find that your web application won’t work correctly until the time catches up.  Its all to do with the date stamp in the assemblies, when you install your application onto a server in california the timestamps on the assembly files may be in the future and parts of the ASP.NET framework will refuse to load them.  Just by waiting 8 hours for time to catch up the problem will resolve itself!  Its defiantly worth saying this doesn’t effect all server setups I had no problems with a customer running server 2008 in a different timezone, I only came across this problem with an AJAX enabled system when a customer was running server 2003, but I haven’t had time to test different scenarios

I installed the application the AJAX was ‘working’ however nothing was styling correctly

I viewed the source of the page and started debugging by copying the WebResource.xsd url into different tab, I was surprised to see the following error:

Server Error in '/' Application.

Specified argument was out of the range of valid values.
Parameter name: utcDate

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.ArgumentOutOfRangeException: Specified argument was out of the range of valid values.
Parameter name: utcDate
Source Error:

An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.

I returned to the system after 8 hours and the site was working and the error was gone! Be careful out there, this was a fully patched server 2003!

500.19 Internal Server Error, There is a duplicate ‘system.web.extensions /scripting /scriptResourceHandler’

by Jon 29. October 2010 22:22

Http Error 500.19 There is a duplicate ‘system.web.extensions/scripting/scriptResourceHandler’

After shipping your asp.net 2.0, 3.0 or 3.5 application to a new server you get the following error:

There is a duplicate ‘system.web.extensions/scripting/scriptResourceHandler’

Don’t worry you haven’t done anything wrong, your are just trying to ship to a new server that has been configured to use .NET 4.0 as the default, and lucky for you it is a quick and simple configuration change to fix it:

Change Application Pool to .Net Framework v2.0

  • Open Internet Information Services (IIS) Manager
  • Goto the Application Pools screen
  • Open the Application Pool offending web application(s) are using
  • Change the Application Pool to use dotnet 2.0 instead of .net 4.0
  • Hard Refresh the erroring page with a <Ctrl> F5

Dotnet Gets it wrong sometimes: 'mycontrol_ascx' is ambiguous in the namespace '_ASP'

by Jon 7. June 2010 16:27

When compiling larger more complicated ASP.Net projects which contain lots of user controls dotnet can get it wrong.  Im running the latest version of vs2008 with all the last patches but I still get occasional niggles.  Ive been getting an error telling me a control is ambiguous when I know it is totally unique.  The solution appears to be to tell the compiler to stop being quite so clever:

Find this, or a similar line in your web.config:

<compilation debug="false" />

Modify it and add batch="false", this stops the compiler being too clever.

<compilation debug="false" batch="false" />
