Debugging Not Working on .NET 4.8 Isolated Azure Functions Project both in VS 2022 and VS Code IDEs

[HariKrishna598]

Steps to Reproduce:

1. Created the .NET 4.8 V4 Isolated Azure Functions Project - basic Http Trigger

2. without debugging working fine from VS IDE but not from VS 2022
   

3. Running the function with debugging is not working - debugger points are not hitting the code.

Following this MS Doc,

• Kept debugging points at the code FunctionsDebugger.Enable(); and also in HttpTrigger Function Code.

• Not Sure which process to be attached for debugging the .NET 4.8 Functions Isolated one.
  

• But tried this cmdlet func host start --dotnet-isolated-debug in the VS Code Terminal of the same project - without hitting the breakpoints, it directly showing the output
  Please Assist!

Also what is the core-tools version you have in your machine?

I suspect your visual studio instance failed to refresh the azure functions tools automatically. You can manually do this refresh by following the instructions here. Let us know if that solves your problem.
