TinyCLR OS 2.1 first preview is here!

Originally published at: https://www.ghielectronics.com/2020/11/03/tinyclr-os-2-1-first-preview-is-here/

The original plan for the remainder of 2020 was to continue improving the 2.0 release; however, it turned out that the 2.0 release was stable and not much needed to be fixed. So, what did we do? We started working on 2.1 and added some serious features. Please see the full release notes.

Release Notes


One of the top new added features is DigitalSignal, which is a non-blocking hardware-backed signal timing API for measuring and analyzing digital signals. It is documented under Signal Control.

Can’t download TinyCLR Config v2.1.0 preview 1

Window10 may block it, you need window 10 allows to download this tool.

Are there instructions on how to convert a 2.0.0 project to 2.1.0.preview1?

If I load the project into VS2019, and go to Nuget packages for the solution, there is no 2.1.0 version to upgrade to?

I managed to update but I had to download the update and create a local directory as there was no online upgrade version.


We do not make previews available on NuGet.org so what you did is the only way.
