I have migrated my ASP.NET MVC 2 project to VS 2010 + .NET 4.0. Now when i start the application i get a lot of "CultureNotFoundException" in IntelliTrace and Output/Gebug window :

A first chance exception of type 'System.Globalization.CultureNotFoundException' occurred in mscorlib.dll

I know what "A first chance exception" means, but when i try to debug(added "CultureNotFoundException" into Bebug/Exceptions[Thrown]) why ex. is thrown i got this detailed exception text:

System.Globalization.CultureNotFoundException occurred Message=Culture is not supported. Parameter name: name designer is an invalid culture identifier. Source=mscorlib ParamName=name InvalidCultureName=designer StackTrace: at System.Globalization.CultureInfo..ctor(String name, Boolean useUserOverride) InnerException:

I wonder why .NET is trying to create CultureInfo with name "designer"?

Isn't it bug?

I had a similar issue with the CultureName "UserCache". To resolve this I deleted all the folders from in here:

C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files

For other people that have this problem, this is usually an exception that is ignored.

Go to the Debug menu -> Exceptions... and ensure that you have everything unchecked for the Exception list.

.NET 4.0 - CultureNotFoundException - .net-4.0 - html, NET Framework Version:4.0.30319, IIS 7.5 , win 2012 r2. 2. Regional settings are set correctly on the web servers (to Japanese). Any pointers on  On Windows 7 and later operating systems, the .NET Framework retrieves culture data from the operating system. The CultureNotFoundException exception is thrown if the operating system is unable to find the culture, and the culture is not a custom culture or a replacement culture.

This is actually by design in System.Web (at least up until .NET Framework v4.0), not necessarily the best approach, but it works.

You can find a more detailed description here, but it basically happens because ASP.NET checks every single folder to see if it contains satellite assemblies, and throws an exception otherwise.

Given that satellite assemblies live in folders with predictable names, one would wonder why they would decide to do this rather than only check folders that match the pattern, particularly since handling exceptions is rather expensive computationally compared to a simple conditional check.

I was curious as to the cause to see if there was something I could personally do to eliminate this particular annoyance.

The Exception is a side effect of calling, "System.Web.UI.Util.IsCultureName(name)"

The first time it's called in my MVC3 application is in regards to a directory called "UserCache", which is in the same directory as several directories with the expected culture names "en-US", etc. .Net is trying to find Satellite directories for the application.

It's called multiple times, even relating to files that are culture files, "EditorLocalization.bg-BG.designer.cs" for example (actually all of these that are in App_GlobalResources). [ What the code does here is to take all the files in App_GlobalResources, and see if the file ends in a CultureName, again calling IsCultureName.

So there's nothing you can really do to avoid this... In production where the .cs classes won't be there, perhaps it won't happen. It certainly slows down startup quite a bit, though!

In any case, in my mind it's a total bug that Microsoft throws an exception inside, "IsCultureName().

  • see stackoverflow.com/questions/868880/… for a similar problem and explanation with a folder "uploads"
  • kill iisexpress.exe if files are locked to delete.
  • What is app is in azure? how should i do this?
  • Interesting, how this error started from no where. After taking your suggestion to uncheck the Exception, I noticed that instead of the dual list I normally see there is only one list. idk if that helps get to the bottom of how this comes about.
  • not sure wjy I now have this problem when try to debug... I not changed anything and from one moment to another it starts to fail, at least I can continue debugging now,thanks for sharing this tip, it saves me!
  • Depending on your config it can also be repaired by enabling "Just my Code" option under Options > Debugging > General > "Enable Just My Code"
  • Ignoring the problem is NOT the solution.
  • This doesn't help if it's some library I use that gets the exception.
  • I did, but didn't foud anything.
  • Wow, that's an old version of VS.NET :-)
  • That is actually incorrect mate, this is a bug in System.Web, see my reply.
