No recent NuGet release #35

More than seven months ago there was caching added to the DeviceDetector.NET, that implementation is still not released as a NuGet package.

When I run the Visual Studio Performance Profiler on the current release (4.2.0) it reports that DeviceDetector.NET creates almost 50,000 objects every page load on our web sites. Performance Profiler reports that DeviceDetector.NET creates 20,000 RegexNodes, 13,000 arrays of RegexNodes and 12,000 Generic Lists with RegexNodes. Not counting 5,000 ints, 3,500 StringBuilders and other objects. This generates a lots of memory management and garbage collecting.

So caching is more or less needed for this to work in production.
