Hello,

I'm trying to get debugging on windows 10 to work.
d_test.d
```D
void main() {
	int i;
}
```
I compile with:
dmd -g -gf -m64 .\d_test.d

I load the msvc debugger with
devenv /DebugExe .\d_test.exe

latest visualD installed.

I can step into the program, but when I add `i` to the watch 
window,
msvs 2022 enters an infinite loop, allocating memory indefinitely 
(I watched until it passed 10GB).

Any tips?
How do other people debug on windows?

Thank you, Python, for taking the time to respond.
Yes, it seemed to me that Visual D would provide the best 
out-of-the-box experience, since it's been around for a long time.

I have somewhere some instructions on windbg which my students 
pointed me to at some point. Have you given that a try? I can try 
to find them in the meantime.

Hello Mike.

Thanks for trying to help. I've watched some of your vids on 
Youtube, and appreciate your work.

I've given WinDBG a try following your suggestion.
It's an improvement in that the infinite-loop-with-memory-leak 
doesn't happen and I can inspect the value of an int.
However, I can't inspect arrays because it doesn't know D, only 
C/C++.

What I'm really looking for is to get VisualD working properly, 
as demonstrated on the official site.

https://rainers.github.io/visuald/visuald/Debugging.html

I had to set up a lot of paths manually, for it to find the 
visual studio linker and several of the linked libraries, like 
user32.lib.
Not sure what I could have done wrong there but I can't imagine 
what else could be the problem.

Has anyone else had issues with inspecting variables in VisualD?

Hey! Thanks for the suggestion.

I'd rather figure out whatever is the problem between my 
particular Visual Studio configuration and what VisualD needs to 
work.
I installed it on another machine today and it worked almost out 
of the box, except for having to restart Visual Studio.
I had hoped someone may have experience with similar issues.

Out of curiosity, how do you go about debugging Dlang specific 
features with remedybg, like ranges, associative arrays, mixins 
or templates?
