No, you didn't create an ActiveX component in .NET. The compilers cannot target building a true ActiveX component. You created a COM-exposed library.

The certificate you use to sign the code must be verifiable to a browser. If you're using a cert you generated yourself on your machine, it won't work. The browser has no way of verifying the authenticity of the cert. You have to get a code-signing cert from a public certificate authority, like Verisign.

If the client does not have the appropriate version of the .NET Framework installed (whatever version you built your code against), your component won't work at all.
