I would rather not say how long it took :-). Actually, it took a few hours. I had right-click on any file to see that you could open it with a different editor.

After I do that, I can open it, then take the .mmBusinessObject out of there and continue opening the thing as before. I actually HAD to remove .mmBusinessObject, as the compiler started complaining if I left it in.

>>Sorry for the vague title. I wasn't sure how to explain it :-).

>>I just upgraded from verion 1.1 to version 1.2 of MM.NET. After upgrading, I opened the Order System Business Object solution I had built earlier (either version 1.0 or 1.1 of MM.NET). When I tried to open the file Business.cs, I got an error. Something similar to:
>>
>>The base class 'OakLeaf.MM.Main.Business.mmBusinessObject' cannot be designed.
>>
>>After awhile, I figured out how to open the file (right-click, Open With..., C Sharp Editor with Encoding). In my file I had:
>>
>>

>>using OakLeaf.MM.Main;
>>using OakLeaf.MM.Main.Business;
>>using OakLeaf.MM.Main.Security;
>>using OakLeaf.MM.Main.Managers;
>>
>>namespace Acme.OrderSystem.Business
>>{
>>	/// <summary>
>>	/// Application-level Business Object class
>>	/// </summary>
>>	public class ABusinessObject : mmBusinessObject
>>	{
>>		public ABusinessObject()
>>		{
>>			DatabaseKey = "Northwind";
>>		}
>>	}
>>

>>
>>I changed the definition of the class to:
>>
>>

>>public class ABusinessObject : OakLeaf.MM.Main.Business.mmBusinessObject
>>

>>
>>And I was able to open the file normally, no errors like before. Then I changed the definition of the class back to the way it was originally, without the explicit reference:
>>
>>

>>public class ABusinessObject : mmBusinessObject
>>

>>
>>And it worked when I tried to open it again normally. Anyone have any idea what's going on?
