I want to build a dotnet application

• This dotnet application will require
  • dotnet sdk to build
  • dotnet runtime to run
• The project is Refer Here
• Dotnet largely has two flavors
  • Dotnet
  • Dotnet core
• This project requires dotnet core 10
• dotnet build process
  • dotnet has build (compile) and publish (ensure all artifcats are at one location)
  • configuration:
    • Debug
    • Release
• Steps
  • clone the project git clone https://github.com/Azure-Samples/dotnetcore-docs-hello-world.git
  • Install dotnet core 10 on ubuntu 24.04 Search for Installing dotnet core sdk 10.0 on ubuntu and give me sources
  • dotnet build –configuration Release
  • dotnet publish –configuration Release -o
• steps

git clone https://github.com/Azure-Samples/dotnetcore-docs-hello-world.git
cd dotnetcore-docs-hello-world/
dotnet build --configuration Release dotnetcoresample.csproj
# tests are missing
dotnet publish --configuration Release -o ./published/ dotnetcoresample.csproj
tar -cvzf dotnetcoresample.tar.gz ./published/

• How can i do this in github actions
• Create a new folder .github/workflows
• Create a file with anyname with extension .yml or .yaml

build.yml

• Now we need to understand options, configure runner and write steps.
