Step Over sometimes executes a lot more than one statement

[TonyValenti]

Description

When I'm debugging code, I use F10 (Step Over) to walk through one line of code at a time.
In .NET 8x, this worked fine.
In .NET 9x, sometimes it seems like it runs a TON more code until it hits a breakpoint.

I suspect I might be running into some variant of #109785 and I specifically notice this happening in ForEach code as described in #109812 .

I see this is slated to be fixed in .NET 10.0, however, this is a major annoyance and I am very hopeful this will be approved for servicing.

Reproduction Steps

Not sure.

Expected behavior

"Step Over" works like .NET 8.0

Actual behavior

"Step Over" sometimes works like "Continue"

Regression?

Yes.

Known Workarounds

Use .NET 8.0

I have this bug too.
For me it is not related to for each at all
Also i see this is added to the dotnet 10 milestone, that's crazy: this a bug preventing normal debugging workflow

For me hot reload also doesn't work in dot net 9

Ya. Debugging really sucks in .NET 9.0 right now.

If I had to guess, it was added to 10.x as a matter of policy, but I'm about 100% certain that once everybody gets back from holiday (and enough people complain here), this will be approved for servicing pretty quickly.

Same here

I have the same issue. It happens all the time and is very tricky. I cannot debug effectively currently.

Wait what. Is this not going to be fixed anytime soon? Do you have a source?

This bug is genuinely unworkable for me. When pressing F10, it keeps going significantly further than what I want. I am trying to debug geometrical algorithms. I can only do this when I know exactly where I am in this process. It is impossible to do when it goes all over the place. I am trying to combat this by putting a breakpoint every other line, but this is simply not working.

When will this be fixed?
