#
# Build this image with
#
#   docker build -t dotnet-dev:0.0.1 -f Dockerfile .
#
# Create the container with
#
#   docker create --name dotnet-dev dotnet-dev:0.0.1
#
# Run the container with 
#
#   docker start dotnet-dev
#
# To run the image in a throw-away container execute
#
#    docker run --rm --name dotnet-dev -it dotnet-dev:0.0.1
#
# In this case you don't have to create the container.
#
# If you want to overwrite the entrypoint do something like
#
#    docker run --rm --name dotnet-dev -it --entrypoint /bin/bash dotnet-dev:0.0.1
