Validation works only when not debugging RRS feed

    Hi - just starting with DD - following some of the videos and tutorials.

    I've got the following override method:

        public partial class user
            partial void Onusr_salChanging(string value)
                if (value != null && value.Substring(0, 1) != value.Substring(0, 1).ToUpper())
                    throw new ValidationException("Titles must start with an upper case letter!");

    If I run with debugging, I get the following error:

    System.ComponentModel.DataAnnotations.ValidationException was unhandled by user code
      Message=Titles must start with an upper case letter!
           at tester2Model.user.Onusr_salChanging(String value) in c:\Source\DotNet_Ver40\Dynamic2\App_Code\AutoMetaData.cs:line 397
           at tester2Model.user.set_usr_sal(String value) in c:\Source\DotNet_Ver40\Dynamic2\App_Code\Model.Designer.cs:line 1889

    It works fine from "run in browser" but not if I run with debugging.  I'm not sure if this is a debugger setting or something else - I've searched the forum and found similar postings, but no solution.

    I think that normal [:)] in debug mode it does tend to catch exceptions then.

    Thanks for the reply.

    I was basically following the example here:


    The presenter ran the example in debugger mode - he didn't get the exception - his validation code handled the exception as you would expect.

    That's why I'm wondering if it's not a specific visual studio debugger setting (I'm running VS2010 express)?

    I've seen this issue with Visual Studio on 64-bit machines.  Have you tried pointing it to IIS Express?

    Is your machine 64 bit?  I don't have VS Express to test on here.
