@Mike is correct. TinyCLR fonts currently use the same format as NETMF, so you can use any existing fonts you may have. Just add them as a resource to your project then you can access them like normal: Resources.GetFont(Resources.FontResources.MyFont).
Using fonts NinaB.tinyfnt and small.tinyfnt as a resource.
I just copied the Resources Folder from a old NetMicro application (VS 2013) into my VS 2017 application.
(Well I have to try and remember all the steps I really had to do)
My test is a kludge by any REAL programmers standards but I have fun anyway.
I do have a problem with my displayController settings because X is off by 27 pixels. but other than that at least the display works.
(I’ll have to ask theEXPERTS about that).
