Went through the Jump Start for creating a business object from entity framework. This worked for me.

I have a new SQL Server database for which I created an Entity Framework from database. I removed all Navigation properties. I verified all settings were the same as when going through the jump start.

I then used the Business Layer Generator making sure all selections were the same as in the jump start. After the business objects are created I get the below errors for each of the table objects when I attempt to build the solution. Some of the tables are from the MMSecurity.sql script and they also get the errors.

Partial declarations of 'Pool.BusinessEF.Role' must not specify different base classes C:\mm.net\Pool Business Objects\EntityDataModel.cs 411 26 Pool Business Objects

Same message above for all tables generated.

Have you seen this before?
