Here’s an example of how to create a custom culture in Whidbey.  Its changed a bit from earlier versions, so this code is based on Beta 2 behavior.  This should be what you see in RTM. J

 

This sample creates a custom culture with the name “en-US-shawn”, changes a couple things and then uses that culture to display that we did indeed get custom behavior.  It then unregisters it.  Copy the example to something like cultures.cs and then use

            csc /r:sysglobl.dll cultures.cs

            cultures.exe

 

Output is something like:

Data from our new culture:

en-US-shawn

Shawn's version of en-US

3/8/2005 17:33:50 PM (shawn)

 

Data from our new culture's parent:

en-US

English (United States)

3/8/2005 5:33 PM

 

This WILL NOT compile on previous prerelease versions, so be patient J  I had questions though so wanted people to be able to see how the custom culture mechanism worked.  If for some reason this culture doesn’t unregister, delete the %windir%\globalization\en-us-shawn.nlp file by hand.
