Bug: Unbound breakpoint in .net5.0

Environment data

dotnet --info output:

.NET SDKs installed:
  3.1.401 [***]
  5.0.100 [***]

VS Code version: 1.52.1

C# Extension version: 1.23.8

OmniSharp log

A lot of lines like this:

[info]: OmniSharp.OmniSharpWorkspace
        Miscellaneous file: d:\****r\obj\Debug\net5.0\Razor\*****\SurveyPrompt.razor.g.cs added to workspace

Steps to reproduce

1. Build a .NET5.0 APP based on the blazorserver template.
2. Set a breakpoint somewhere.
3. Debug and wait.
4. The breakpoint is hit.
5. Then, add a new line above the hit line.
6. End the debug session.
7. Start the debug session.
8. The breakpoint is an unbound breakpoint. In other words, the breakpoint sign is hollow and the breakpoint will not be hit.

Expected behavior

The breakpoint should never be an unbound breakpoint.

Actual behavior

The breakpoint happens to be an unbound breakpoint.

Additional Issues

I reckon that, although not 10/10 for sure, this issue is also relative:

If any additional context and information are needed, I will more than happy to provide for this issue.

I had this same problem just now. Because I am making a Console app I can see in the Terminal that the output is the same as my previous code.

To fix this I stop the debugger and run either of these commands: dotnet run

dotnet build

It seems the debugger might not actually execute the “preLaunchTask” ?

It turns out that it is not omnisharp…

I forgot to update the program path from netcoreapp3.1 to net5.0 in launch.json. Sorry for this issue…
