Visual Studio 2022 调试器认为我更改了代码并想要热重载

Question

EDIT: Good information provided below to diagnose, but the issue was I was running Visual Studio 2022 17.3. Version 17.4 is required for .NET 7, and I had just installed that. Once I installed the latest version of VS, all my problems went away. Install with Visual Studio

Suddenly today, debugging my ASP.NET Core 6 and 7 apps suddenly has stopped working. I hit F5 to debug, it stops on my breakpoint, but as soon as I continue or step into, I'm shown this dialog:

I haven't made any changes to code, I'm simply trying to continue after I've stopped at a breakpoint. This just started happening today and I can't figure out what I did.

Answer 1

I haven't made any changes to code, I'm simply trying to continue after I've stopped at a breakpoint. This just started happening today and I can't figure out what I did.

Well, if your visual studio stop working for debugging all type of application, please check following configuration:

1. Tools > Options > Debugging > .NET/C++ Hot Reload

2. Tools > Options > Projects and Solutions > ASP.NET Core >

Furthermore, If you select the Always rebuild option in the dialog box, you won't see the dialog box again in the current Visual Studio session, and Visual Studio will automatically rebuild and reload instead of showing the dialog box.

Note:

In addition, as you can see above in the first release of Visual Studio (version 17.0) the standard Edit and Continue dialog is still shown when using Hot Reload with the debugger. This was a bug and has been resolved starting with 17.1 Preview 2 release.

If you still need more details about the issue you are having with, I would higly recommend you to check our official document here.

If issue still perist:

After checking above configuration, if your issue still persists and if you are not using Visual Studio (version 17.0) then you still reset your unknown setting in visual studio as following:

Go to Tools > Import and Export Settings.

Then No, just reset settings

Finally, restart Visual studio.
