Recently, I've been playing around with a Raspberry Pi 4B that I just picked up. It's an awesome little device for the price; I'm really impressed with what it can do so far. I'm planning to use it as a driver for a DIY observatory I'm working on. As part of that, I'm writing an application that can remote control my camera and a custom motorized mount for my telescope. I decided to use .NET Core as my framework of choice; I'm a big fan of C# and its ecosystem, and the fact that .NET Core 3.1 works on ARM64 systems (which is what the Pi 4B runs) makes it a no-brainer.

Unfortunately, .NET Core doesn't come with any cross-platform UI frameworks out of the box. I use WPF a lot for Windows projects, but one of its biggest weaknesses is that it isn't supported on anything else. The WPF repo already has a very long thread about this very topic, so it's definitely one that's on a lot of peoples' minds. That be

You might want to read this to get an introduction to armel vs armhf.

If the below is too much, you can try Ubuntu-ARMv7-Qemu but note it contains non-free blobs.

Running ARM programs under linux (without starting QEMU VM!)

First, cross-compile user programs with GCC-ARM toolchain. Then install qemu-arm-static so that you can run ARM executables directly on linux

If there's no qemu-arm-static in the package list, install qemu-user-static instead
