Background
I'm working on personal project, (a mobile app), in which geolocation is a feature. The users log a location in a MongoDB, (if commercially viable, it'll be an Azure CosmosDB, but for now I'm testing with simulated data locally). To account for scale, I'm developing with the mind that I'll have 10'000'000 locations, (quite unrealistic, but I've screwed up before, underestimating, so i multiply my calculated max with 10)

The need
I need a "management"-application, which preferably has a world map with "dots", (this is acheivable with Bing Maps and it's WPF MapControl, and using Pushpins).

The issue
When I tested with 100'000 locations, the app uses 3GB RAM, takes 10 minutes to load, and navigating it's tabs is beyond slow. if I were to scale to 10'000'000 locations, it would probably kill my computer

Any help, thoughts and input would be greatfully recived

What I have tried:

Google only pushes DevExpress and Telerik in my face, and nothing in my price-range

You should not be trying to build such large amounts at one go. As with virtual lists you need to collect the data and render it only as the user requests more, or the data needs to be displayed in the view.

The issue is that the "master map", needs to show the locations found.

And I'm actually surprised that the Bing Maps control, don't have the features to handle that much data, (or load it in a better way)

I think you will find that they do what I mentioned above. The information is in the database but the points are only mapped as and when they need to be shown. Trying to manage a map of the world with all points ready marked and hold that in memory will never work.

The solution is to use html and the many bing maps functions available there. E.g heatmap
