.NET Annotated Monthly | September 2019

Ahhh, September. It’s such a great month that it’s been memorialized in a popular song by Earth, Wind, and Fire. In many places, school starts again and autumn will soon be upon us (for the north half of the world). As the weather becomes milder, it’s nice to sit outside and catch up on some technical reading. Besides, once the kids go back to school you can actually get some reading done.

    I recently purchased a Raspberry PI 4 in order to get started on some IoT ideas with ASP.NET Core API. My attempts to get the OS running on this platform have failed. I have not found a resource that says that Microsoft is going to continue to support IoT on this device.

    Do you have insight as to what Microsoft’s plans are? Do you have resources that show what it takes to get Windows IoT running on this device? If not Windows IoT on Raspberry PI 4, then what alternative OS could host .NET Core 3? Thanks for any insight you can provide.
