.NET 7 on FreeBSD 13.2

After getting it up and running, I sent a quick toot about having .NET 7 running on my FreeBSD VM. It got a lot of boosts and favorites.

To make the process easier for others and to make sure credit is given where due, I decided to make this little gist.

Credits

I did nothing here but find the right bits of instructions and follow them. It looks like Thefrank and sec are the driving forces behind getting .NET working on FreeBSD. More information is on the FreeBSD wiki's .NET page.

FileNotFoundException

A few months back, I wrote a simple little Windows desktop application using WPF. It's built for .NET Framework 4.5, which means it should run in 4.5 through 4.8 without any issues. Outside of some core .NET assemblies and the WPF ones, it has a whopping three dependencies:

1. Genesyslab.Sip.Endpoint.dll
2. Genesyslab.Sip.Endpoint.Provider.Genesys.dll
3. Newtonsoft.Json.dll

This application has been used internally on my network, internally on the other half of the company's network (we had a big merger, the networks are linked but only enough to get the important things working on both sides), and internally on some vendor networks. At launch, it connects to a web service of mine to pull down configuration stuff, and user-selected options then dictate what Genesys servers those first two dependencies connect to. Nice and simple.
