Setting up a .NET development environment

This tutorial shows how to prepare your local machine for developing .NET and .NET core apps that run on Google Cloud and call Google Cloud APIs.

Install a development environment

The recommended development environment for running the .NET tutorials and sample apps in this documentation is Visual Studio or Visual Studio Code.

Create a Google Cloud project

Create a Google Cloud project to run your apps. Google Cloud projects form the basis for creating, enabling, and using all Google Cloud services.

Authentication

During local development, your .NET app must authenticate itself in order to interact with Google Cloud APIs. The following instructions describe how to create a service account key to authenticate your app. Apps can use this method to authenticate locally and when deployed to Google Cloud. Read more about authentication, including how authentication is handled once your app is deployed.

Create a service account key for authentication

Cloud Console

  1. In the Cloud Console, go to the Create service account key page.

    Go to the Create Service Account Key page
  2. From the Service account list, select New service account.
  3. In the Service account name field, enter a name.
  4. From the Role list, select Project > Owner.

  5. Click Create. A JSON file that contains your key downloads to your computer.

Command line

You can run the following commands using the Cloud SDK on your local machine, or in Cloud Shell.

  1. Create the service account. Replace NAME with a name for the service account.

    gcloud iam service-accounts create NAME
  2. Grant permissions to the service account. Replace PROJECT_ID with your project ID.

    gcloud projects add-iam-policy-binding PROJECT_ID --member="serviceAccount:NAME@PROJECT_ID.iam.gserviceaccount.com" --role="roles/owner"
  3. Generate the key file. Replace FILE_NAME with a name for the key file.

    gcloud iam service-accounts keys create FILE_NAME.json --iam-account=NAME@PROJECT_ID.iam.gserviceaccount.com

Next, set the environment variable GOOGLE_APPLICATION_CREDENTIALS to the path of the JSON key that was downloaded. In PowerShell, the commands are:

For this PowerShell session.

PS > $env:GOOGLE_APPLICATION_CREDENTIALS = "$env:USERPROFILE\Downloads\your-project-id-dea9fa230eae3.json"

For all processes created after this command.

PS > [Environment]::SetEnvironmentVariable("GOOGLE_APPLICATION_CREDENTIALS", "$env:USERPROFILE\Downloads\your-project-id-dea9fa230eae3.json", "User")

(Optional) Install .NET tools and SDKs

Even though you can create and manage Google Cloud resources via your web browser using the Google Cloud Console, if you'd prefer to manage your Google Cloud resources from within Visual Studio or from the command-line, you can consider installing the following tools:

  • Cloud SDK: The Cloud SDK is a command-line interface for Google Cloud products and services.

  • Tools for Visual Studio: Tools for Visual Studio enables development in Visual Studio on Google Cloud.

  • Tools for PowerShell: Tools for PowerShell is a set of cmdlets for Windows PowerShell that lets you manage Google Cloud resources.
