Hello,I want to create a feature Class within a Geodatabase (the code below).When computing IFieldsEdit.AddField(IFieldEdit)
it crashes and returns "Exception from HRESULT: 0x80040705"
It wouold be grateful if somebody could get any help or ideas to solve this problem.Thanks!Here are some object-values at runtime:IFieldsEdit:base {System.__ComObject} System.MarshalByRefObject {System.__ComObject}

}
catch (Exception e)
{
Console.WriteLine(e.StackTrace);
throw e;
}Thanks.
