Don't want to share a library !

Hi Experts,

I have built a library for my app, but I don't want other app to be able to use my library.
How can I do ?

Thanks in advance for your answers.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

.NET has built in support for this. The key is to sign your code digitally and make your Assembly require callers to have that signature. See <http://samples.gotdotnet.com/quickstart/howto/doc/security/CodeIdentityDemand.aspx> for a very simple explanation. It's pretty easy to get working, but you should be well familiar with .NET code security as a whole prior to deploying such an application. I strongly advise at least reading the help topics on security issues and preferably a good book.

You may also want to consider using an obfuscation tool to help keep your source code safe. Taking a look at the links at <http://msdn.microsoft.com/vcsharp/team/tools/default.aspx> and reading the article at <http://www.developer.com/net/csharp/article.php/3292231> might be useful.
