The type RegCloseKeySafeHandle generated for RegLoadAppKey() is not compatible with RegistryKey.FromHandle()

[efraimbart]

The type RegCloseKeySafeHandle which is generated as the out for RegLoadAppKey() does not inherit from SafeRegistryHandle and is therefore not compatible with RegistryKey.FromHandle().

I'm kinda new to the whole Win32 API, so any help to figure where I should be going from here would be greatly appreciated!

I see that SafeRegistryHandle is implemented to call RegCloseKey to release the handle, so that meets the purpose. We should be able to reuse that .NET type rather than generating our own.
