'Declaration <BrowsableAttribute(False)> _ Public Sub New ( _ name As String, _ columnNames As String(), _ isPrimaryKey As Boolean _ )
This constructor is provided for design time support in the Visual Studio .NET environment. UniqueConstraint objects created by using this constructor must then be added to the collection via AddRange. Columns with the specified names must exist at the time the method is called, or if BeginInit has been called prior to calling this constructor, the columns with the specified names must exist at the time that EndInit is called.
