Protect my class Libraries, can I?

[Cablito]

Is there a way to protect my class libraries?

I have for instance, a class library full of my base forms and classes
latter inherited by various projects.

A lot of logic is within those objects and I´d hate to see other companies
or individuals being able to add my DLLs to their .NET solution and using it
at will.

See the reply on "Protecting Assemblies From Un-Authorised Use" there I have
given an example use.

You could use
"System.Security.Permissions.StrongNameIdentityPermissionAttribute"
You will need to sign all your assemblies that call the ones you want to
protect with the appropriate key.
Any "foreign" assemblies that try to call your protected ones should get a
security exception.

You can use the attribute at assembly, class, constructor or method level.

It's not impossible to circumvent but better than nothing.

Write good license agreements, slap a bunch of copyrights on it, and be
prepared to hire a lawyer. There is no way to truly protect source code.

Hi Cablito,

Have a look at "Licensing Components and Controls" in MSDN:
