does .NET connect to Internet to verify digitally signed assembly certificate?I am developing a winforms control which is strong-named and digitally
signed . My customers complain that the control connects to the Internet when it is loaded, but I am sure my code doesn't do that. So my question is whether the .NET runtime does that, probably to check whether the digital certificate is valid ? Thanks Windows, not .NET, will attempt to verify the CRL for an Authenticode-signed
assembly. (This has nothing to do with strong naming.) It is possible to disable this behaviour globally, but not for any single assembly. Since global disabling of the verification on a given machine is hardly unlikely to be desirable, you basically have no way to stop this behaviour as long as your assembly has an Authenticode signature.

your certificate is being checked for revocation against the published CRL location in the certificate. This is usually a web address, so that would probably explain it. Joe K.
