I've been playing with nuget.
It is fantastically easy to package up an assembly and make it available for just anyone to use in their applications. It is beautifully integrated into Visual Studio and I reckon it is actually easier to download a package from the other side of the world and make it part of your solution than it is to add one that you have written yourself on your own machine.
To practice I've packaged up my Bluetooth Manager library. This is a little wrapper class that makes it really easy to use Bluetooth on Windows 10 applications. I've not tried it on Windows 10 on Raspberry Pi (but I've tried it on lots of other systems and it works fine). You can find out a bit more about it here. I use it so that I can print message on my little home made Bluetooth printer, but you can use it anywhere you want to talk over a Bluetooth serial connection.
Oh, and in case you are wondering why it is version 1.0.1 and not version 1.0.0 I found an interesting quirk in nuget. If your library class doesn't have a public constructor the package will fail to work because Visual Studio will complain that the class is "Inaccessible due to its protection level.". That's what happens when you try to use version 1.0.0
