Sage 50 Canadian SDK - how to do wSDBGetDBVer in c#

I am trying to use some of the features described in the documentation that came with the SDK. In the doc, dev-progref.pdf, I've read about the methods and they all seem to start with wSDB. I've seen that the wSDB* methods can be called in C++ and VB. I've also noticed the wSDBOpenDatabase seems to get called simply OpenDatabase in C# by doing SDKInstanceManager.Instance.OpenDatabase.

How can I call  GetDBVer.  (at least I expect that is the format for C#)

I tried to find GetDBVer in the Sage 50 CA SDK help file dev-dotnetref.chm that came with the SDK. According to "Search" it is not there.
