C Sharp

I'm following along with the book, Crafting Interpreters, but I'm implementing jlox in C# instead, as I thought it would help me understand the code better if I had to do some amount of porting. I am running into language specific issues though, particularly, I believe, with how C# handles null.

After implementing the resolver from chapter 11, my interpreter can no longer handle for loops (and probably while loops too, though I didn't test this).

The resolver does not seem to properly store the location of the variable declaration in the for loop in its dictionary. This leads to it passing the wrong 'distance' to the interpreter.

Here's an example:

for (var i = 0; i < 10; i = i + 1) {
    print i;
}

My interpreter will crash with this code that should be valid, because when it encounters print i it won't be able to find the declaration for i. The next chapter of the book is about classes, so this error is not supposed to be here.

I apologize for the complexity of the code and the low amount of comments, my plan was to complete this part of the book and then reread it and go over and comment all my code so I can understand it better. I've attached a link to the GitHub issue on this post, it has a simple explanation and the stack-trace .NET throws when it encounters a for loop.

Please let me know if you need more information.

I won't be surprised if it turns out to be a very simple mistake, but I will facepalm.
