I'm trying to add a newproperty to dbo.Customer. I changed already Customer.cs and CustomerMap.cs. When I try to add a new column in dbo.Customer in SQL Server I get a message
'Customer' table
- Unable to modify table.
Cannot insert the value NULL into column 'ClientNumber', table 'NopTest.dbo.Tmp_Customer'; column does not allow nulls. INSERT fails.
The statement has been terminated.
How I can resolve this problem?
