As a point of order, the bug with nullable types may well be a bug, but it is also a bug on our end because the fields are boolean but have not been marked as NOT NULL in the database when they should have been.
Thanks kimj, your responses are always quick and helpful.

Re the exception - that would be a bug.   We do attempt conversion of the DefaultValue when we stuff it into the entity, and Convert.ChangeType is throwing because of the Nullable<Boolean>.   For now, DefaultValue won't work with nullable types other than string.  We'll add this to the defect list.  Thanks for reporting it.

Re the first post - We take whatever is defined in the DefaultValue attribute for the property in the EDMX file, and don't validate its correctness or make it language-specific.  So, if you modify the EDMX to use DefaultValue="false" for these properties the code should generate correctly for C#.

Just saw your second post ...

Also, I am getting this error when I try to run the app:

It seems the generated code has an invalid setting for the DefaultValue for boolean properties in C#:
    [Bindable(true, BindingDirection.TwoWay)]
    [Editable(true)]
    [Display(Name="Promoted", AutoGenerateField=true)]
    [IbVal.ValidateProperty]
    [IbVal.RequiredValueVerifier()]
    [IbCore.DBDataType(typeof(Boolean))]
    [DefaultValue(False)]
    [MsSer.DataMember]
    public Boolean Promoted {
       get { return PromotedEntityProperty.GetValue(this); }
       [global::System.Diagnostics.DebuggerNonUserCode]
       set { PromotedEntityProperty.SetValue(this, value); }
    }

Notice the upper case False. A lower case false works fine. A simple find and replace has fixed it for me. Am I doing something wrong though? Is my mapping file wrong somewhere? Thanks, Simon.
