Can TextPad work with C#? Reason I ask is because I would imagine you would have to download some kind of C# Development Kit or SDK and I don't know if Microsoft allows that?
"C#" is a language, TextPad is an editor. Whichever development environment you're using: if its options allow using an external editor then yes: you can use TextPad (just like any other editor). But (of course) it would lack highlighting breakpoints and miss features like evaluation and auto completion and all that. Not sure if you understand the differences between a software which is only an editor and a software which comes with a compiler, a debugger, an editor and much more tools for one or more programming languages.
I would need to know what to enter in the text field boxes. Where it says Command Line and Arguments and Path.
There isn't any videos on YouTube that talk about how to set TextPad up with C#, so if you have any knowledge of how to configure these boxes please post.
