A developer is building a .NET 8 web app and wants to create a minimal Docker image. The Dockerfile uses the .NET SDK image to build and the ASP.NET runtime image for the final stage. After writing the Dockerfile, the developer runs `docker build -t myapp:latest .` but the build fails because the SDK image cannot be pulled. What should the developer do first?

Change the base image in the Dockerfile to `mcr.microsoft.com/dotnet/sdk:8.0` and ensure the tag exists.

Run `docker login` to authenticate to Docker Hub before building.

Run `docker pull mcr.microsoft.com/dotnet/sdk:8.0` manually to pre-cache the image.

Use `docker build --pull` to force a fresh pull of the base image.
