There are good reasons for migrating to writing code in the new Windows .NET Framework Common Language Runtime (CLR) environment using Microsoft Visual Studio (VS) 2005, especially if you're struggling with nullable columns in the database.The CLR provides templates for creating new objects and object classes, which reduce the workload for you and incorporate checks for nullability. Among the required methods in the template to create a user-defined data type (UDDT) is IsNullable, which is used to indicate whether or not the object is nullable.VS 2005 and the CLR, with its automated assistance, can help programmers get a handle on NULL.
