Originally created by @waf on GitHub (Sep 9, 2018).

I've created a (very) rough C# terminal using ConPTY. It's barely past "hello world" stage, but I thought it might be useful for others, as it includes the pinvoke constants and declarations required to get everything working.

https://github.com/waf/MiniTerm

It's pretty much a straight-forward translation of the C++ examples (including the work from @bitcrazed's PR). If there's interest, I could submit this in a PR to this repository. I'd need some help getting it up to an acceptable level of quality -- there are still rendering issues I'm trying to figure out.

The core of the interaction with the pseudoconsole is here:

ef13d4ea5e/MiniTerm/Program.cs (L37-L57)

Absolutely, I'd be happy to take a look at the PR :)

I'd add your sample as another child of samples/ConPTY, next to where @bitcrazed's sample will end up.

Nice! Thanks for sharing @waf.

Just wrapping-up final edits to our sample. Will be publishing soon.

Thanks again WAF - I've now published our "EchoCon" C++ ConPTY sample. Will add WAF's sample. Please feel free to submit a PR with your managed MinTerm sample, and we'll work with you to get it added :)

Great, thanks! I'll probably get a PR opened in the next week or so as I work through some of the known issues.

Hi, I seem to be getting mojibake when I try this sample (I realize my prompt of ethanhs▶C:\❯ is not exactly common). I took a look but didn't see anything obvious that could cause this. Thoughts on what could cause this would be appreciated, as I am very interested in using ConPTY, but I am confused as to why this would break.

We don't support characters above U+FFFF yet. ▶ and ❯ both have codepoints over U+FFFF.

Also, I'd highly recommend that you choose to file a new issue next time instead of bumping an old closed one.
