生成密封类

Question

Using linq to sql I would like to generate some sealed classes in a data context. Apparently that can't be done.

When I try to extend a generated class, let's say ApplicationUser by a partial part like this

sealed public partial class ApplicationUser
{ }

I get compilation errors (summarized)

'SendPropertyChanging()' is a new virtual member in sealed class 'ApplicationUser'

and

'SendPropertyChanged(string)' is a new virtual member in sealed class 'ApplicationUser'

obviously because these methods are generated as protected virtual .

Is there a way to let linq to sql generate selected (not all) classes as sealed?

Answer 1

You can generate a sealed class by editing the properties in the designer:
