Describe your experience with containerization using Docker in projects.

In C# projects, I used Docker for containerizing applications, which allowed creating isolated and reproducible environments for development and deployment. I usually created a Dockerfile specifying a base image, such as mcr.microsoft.com/dotnet/aspnet, copying the compiled application files, and setting the startup command.

Example of a simple Dockerfile for an ASP.NET Core application:

FROM mcr.microsoft.com/dotnet/aspnet:6.0
WORKDIR /app
COPY ./publish .
ENTRYPOINT ["dotnet", "MyApp.dll"]

This enabled running the application in a container with the required .NET version, independent of the host configuration. I also used Docker Compose for orchestrating multiple services, such as databases and APIs, which simplified local development and testing.
