ExtendedProperties.Remove method

[CAPICOM is a 32-bit only component that is available for use in the following operating systems: Windows Server 2008, Windows Vista, and Windows XP. Instead, use Platform Invocation Services (PInvoke) to call the Win32 API function CertGetCertificateContextProperty and obtain the properties. For information about PInvoke, see Platform Invoke Tutorial. The .NET and CryptoAPI via P/Invoke: Part 1 and .NET and CryptoAPI via P/Invoke: Part 2 subsections of Extending .NET Cryptography with CAPICOM and P/Invoke may also be helpful.]

The Remove method removes an extended property from the collection.
