Reading in JSON-RPC for LSP msg returning Null???

So long story short Im building an LSP and it has been a process. I finally got it hooked up to read in stdin from vscode only for my message to never return anything but null.

✅ Auto Updating WPF applications options and best practices

So I'm building an internally facing application for a client, I've spent some time getting to know WPF and C# as this is my first major project.

The application is being hosted with GitHub in a private repository, I initially had planned to handle updates entirely by using GitHub releases however open to suggestions on better/alternative ways to handle this.

Any help would be greatly appreciated thanks 🙂...

I'm having it parse these from a URI, but it seems to get stuck on the ReadElementContentAsString() method (I've set up message boxes as debugging behaviour, and the one right before the call to the method appears, but nothing ever happens, and the next one's never triggered. the app isn't frozen, though). edit: here's exactly where it gets stuck https://github.com/win-ini/niuniakweb/blob/master/niuniakweb1/Form1.cs#L81...
