How to register custom WMI provider

I came across LM's overview of WMI (https://www.logicmonitor.com/wp-content/uploads/2015/07/Comprehensive-Guide-to-WMI-1.pdf) which inspired me to try creating my own WMI provider. However, Microsoft documentation on the same is quite limited and both the two ways of developing a provider are failing at the last stage of registering in WMI repository (one way is to create MOF, then convert mof to provider header and source files & the other way is to code header and source files yourself). Is there someone who can help me develop a WMI provider? Do get in touch with me, I would be happy to share more details with you. 

FYI Error: Provider Load Failure  (even though provider is visibly registered in the WMI regedit registry) when attempting to access from Windows  admin CMD
