TestUnhandledCrashConsoleApp

Test for issue #118049 (Ubuntu Linux)

1. Clone TestUnhandledCrashConsoleApp source code
2. Modify TestUnhandledCrashConsoleApp.csproj to select the target framework

    <TargetFramework>net10.0</TargetFramework>

Or

    <TargetFramework>net9.0</TargetFramework>

3. Open terminal session and change current directory to the root directory of the project
4. Publish the application as a self-contained executable for the Linux x64 runtime.

    dotnet publish -c Release -r linux-x64

5. Modify Docker file to pick either .NET 9 or .NET 10 by commenting/uncommenting either of:

   FROM mcr.microsoft.com/dotnet/aspnet:10.0.0-preview.6-noble-amd64

OR

   FROM mcr.microsoft.com/dotnet/aspnet:9.0

and respectively either of:

   COPY ./bin/Release/net10.0/linux-x64/publish/ .

OR

   COPY ./bin/Release/net9.0/linux-x64/publish/ .

6. Save Docker file
7. Execute

   docker build -t pid1-crash-app .

8. Execute the following test cases:

A. FAILS in 9.0, PASSES in 10.0 preview 6: Application crashes, creates a dump, and then hangs.

docker run --rm -v ~/Downloads:/dumps -e "DOTNET_DbgEnableMiniDump=1" -e "DOTNET_DbgMiniDumpType=1" -e "DOTNET_DbgMiniDumpName=/dumps/coredump.%p" pid1-crash-app

B. PASSES for both 9.0 and 10.0: Application crashes and exits correctly (no dump created).

docker run --rm -v ~/Downloads:/dumps -e "DOTNET_DbgEnableMiniDump=0" -e "DOTNET_DbgMiniDumpType=1" -e "DOTNET_DbgMiniDumpName=/dumps/coredump.%p" pid1-crash-app

C. PASSES for both 9.0 and 10.0: Application is not PID 1, creates a dump, and exits correctly.

docker run --rm --init -v ~/Downloads:/dumps -e "DOTNET_DbgEnableMiniDump=1" -e "DOTNET_DbgMiniDumpType=1" -e "DOTNET_DbgMiniDumpName=/dumps/coredump.%p" pid1-crash-app
