ASP.NET Core is a new open-source and cross-platform framework for building modern cloud-based and internet-connected applications using the C# programming language.
Google Cloud Shell is a browser-based command line tool to access Google Cloud Platform resources. Cloud Shell makes it really easy to manage your Cloud Platform Console projects and resources without having to install the Google Cloud SDK and other tools on your system. With Cloud Shell, the Cloud SDK gcloud command and other utilities such as .NET Core command line interface tools are always available when you need them.
In this lab, you will learn about how to build and launch an ASP.NET Core app from Google Cloud Shell — without ever leaving the browser.
The instructor will be sharing with you temporary accounts with existing projects that are already setup so you do not need to worry about enabling billing or any cost associated with running this codelab. Note that all these accounts will be disabled soon after the codelab is over.
Once you have received a temporary username / password to login from the instructor, log into Google Cloud Console: https://console.cloud.google.com/.
Here's what you should see once logged in :

To get started:
A Cloud Shell session opens inside a new frame at the bottom of the console and displays a command-line prompt. This might take a few seconds as Cloud Shell is spinning a VM.
Wait until the $ prompt appears.
ASP.NET Core is a significant redesign of the traditional Windows-only ASP.NET framework. You can develop and run your ASP.NET Core apps cross-platform on Windows, Mac and Linux.
ASP.NET Core comes with the .NET Core command-line interface (CLI), a new foundational cross-platform toolchain for developing .NET Core applications. This toolchain is already installed in Google Cloud Shell.
In the next section, we use the .NET Core command-line interface to create our first ASP.NET Core app.
First, we need to setup ASP.NET Core in Cloud Shell. To do that, run the following in the default directory in Cloud Shell.
sudo dotnet restore
This should take a minute or so and in the end, you should see something like this.
Welcome to .NET Core! --------------------- Learn more about .NET Core @ https://aka.ms/dotnet-docs. Use dotnet --help to see available commands or go to https://aka.ms/dotnet-cli-docs. Telemetry -------------- The .NET Core tools collect usage data in order to improve your experience. The data is anonymous and does not include command-line arguments. The data is collec ted by Microsoft and shared with the community. You can opt out of telemetry by setting a DOTNET_CLI_TELEMETRY_OPTOUT environment variable to 1 using your favorite shell. You can read more about .NET Core tools telemetry @ https://aka.ms/dotnet-cli-telemetry. Configuring... ------------------- A command is running to initially populate your local package cache, to improve restore speed and enable offline access. This command will take up to a minute to complete and will only happen once. Decompressing 100% 8781 ms Expanding 100% 33846 ms MSBUILD : error MSB1003: Specify a project or solution file. The current working directory does not contain a project or solution file.
In Cloud Shell prompt, dotnet command line tool is already installed and you can verify its version as follows.
Next, create a new skeleton ASP.NET Core web app.
dotnet new razor -o HelloWorldAspNetCore
This should create a project and restore its dependencies. You should see a message similar to below.
Restore completed in 11.44 sec for HelloWorldAspNetCore.csproj. Restore succeeded.
We're almost ready to run our app. Navigate to the app folder.
Finally, run the app.
Application starts listening on port 8080.
Hosting environment: Production Content root path: /home/atameldev/HelloWorldAspNetCore Now listening on: http://[::]:8080 Application started. Press Ctrl+C to shut down.
To verify that the app is running, click on the web preview button on the top right and select ‘Preview on port 8080'.
You'll see the default ASP.NET Core webpage which simply prints Hello World in a new tab.
Once you verified that the app is running, press Ctrl+C to shut down the app.
There! You've just created and launched an ASP.NET Core app from inside Cloud Shell, without once leaving your browser. But that's not all you can do. You can take your newly created ASP.NET Core app, containerize it using Docker and deploy it to Google App Engine. Or you can let Kubernetes manage it all for you in Google Container Engine.
