.NET Framework

As explained in Learn Docker in a Month of Lunches, Second Edition

.NET Framework is Microsoft's Windows-only application development and runtime framework.

.NET Framework is Microsoft's Windows-only application development and runtime framework. Released in 2002 and extended through version 4.8 in 2022, it later evolved into cross-platform .NET. Existing applications can be modernized without rewriting their code by packaging them in Windows containers. section 13.3 section 13.5

A containerized .NET Framework application typically uses:

  • A .NET Framework 4.8 SDK image to restore NuGet packages and compile the C# project with MSBuild. section 13.3
  • An ASP.NET runtime image containing .NET Framework and IIS to host the compiled output. section 13.3
  • Container-specific configuration and startup PowerShell scripts copied separately from the application source configuration. section 13.3

Containerizing Nerd Dinner

A multi-stage Dockerfile builds the unchanged Nerd Dinner application with mcr.microsoft.com/dotnet/framework/sdk:4.8, packages it into an ASP.NET 4.8 image, and serves it through IIS. Build the image with docker build, run it with docker run -d -p 8085:80, and browse to localhost:8085. section 13.3

How Learn Docker in a Month of Lunches, Second Edition covers it

How deep it goes
Explains multi-stage builds, dependency restoration, compilation, IIS packaging, configuration overrides, and local execution.
Examples
Uses the unchanged Nerd Dinner application, a .NET Framework 4.8 Dockerfile, IIS hosting, and localhost port publishing.
What it assumes
Assumes an existing .NET Framework source project and Docker workflow, while supplying the required SDK, runtime, restore, and build steps.
What you can do after
Build it from source and run it in a Windows container with Docker, IIS, NuGet, and MSBuild.
How it connects
Connects .NET Framework with Docker, Windows containers, IIS, ASP.NET, NuGet, MSBuild, and cross-platform .NET.
