Hi Kyle

      I just came across that same problem. I lost some valuable time
since i did not read carefully the error I got:

The type 'MySchemas.SimpleDataset' is defined in an assembly that is
not referenced. You must add a reference to assembly 'MySchemas,
Version=1.0.3072.27689, Culture=neutral, PublicKeyToken=null'.

     Later I noticed that the tables that are part of
MySchemas.SimpleDataset dataset inherit from TypedTableBase class
which is defined as

Namespace:  System.Data
Assembly:  System.Data.DataSetExtensions (in
System.Data.DataSetExtensions.dll)

public abstract class TypedTableBase<T> : DataTable, IEnumerable<T>,
IEnumerable where T : DataRow

     To solve your problems you should reference this assembly
(System.Data.DataSetExtensions.dll) in every project where you use
your custom datasets - that at least worked for my case. I suppose
there are more elaborate ways to solve this problem, but as a fast fix
this could do it.
