dotnet hot reload not working in container with bind mount

[ashrafxcoder]

Describe the Bug

I'm trying to run dotnet container in dev mode (bind mount source code) by running dotnet watch inside container bash, but hot reload does not work it just says: $ dotnet watch ⌚ File changed: ./Program.cs. $ dotnet watch ⌚ No hot reload changes to apply.

But if I try running it locally it works fine and updates does get hot reloaded.

Steps to Reproduce

App.csproj

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net6.0</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>
  </PropertyGroup>
</Project>

Program.cs

while(true)
{
    await Task.Delay(2_000);
    Console.WriteLine("Hello, World!");
}

and finally the command to run: docker run -it --rm -w /app -v "$(pwd):/app" mcr.microsoft.com/dotnet/sdk:6.0 bash -c "dotnet build & dotnet watch"

When I change the console statement to Console.WriteLine("Hello, Docker!"); it says this:
