It involves creating a service account, enabling the API, and downloading a JSON key. The process includes setting up a new C# console project in Visual Studio, adding necessary NuGet packages, and placing the service account key in the project directory. The `Program.cs` file is updated with code to authenticate and then send an API request to list all DPCs and print them out in the console. Finally, run the application.\n"],null,["# .NET quickstart for customers\n\nFollow the steps in this quickstart guide, and in about 10 minutes you have\na simple .NET C# console app that makes requests to the zero-touch enrollment\ncustomer API using a service account.\n\nPrerequisites\n-------------\n\nTo run this quickstart, you need:\n\n- A service account, that's linked to you zero-touch enrollment customer account. See [Get\n started](/zero-touch/guides/customer/service-accounts).\n- Visual Studio 2013 or later.\n- Access to the internet and a web browser.\n\nStep 1: Turn on the zero-touch enrollment API\n---------------------------------------------\n\n1. Use [this\n wizard](https://console.developers.google.com/start/api?id=androiddeviceprovisioning.googleapis.com) to create or select a project in the Google Developers Console and automatically turn on the API. Click **Continue** , then **Go to credentials**.\n2. Set **What data will you be accessing?** to *Application data*.\n3. Click **Next**. You should be prompted to create a service account.\n4. Give a descriptive name for **Service account name**.\n5. Note the **Service account ID** (it looks like an email address) because you'll use it later.\n6. Set **Role** to *Service Accounts \\\u003e Service Account User*.\n7. Click **Done** to finish creating the service account.\n8. Click the email address for the service account that you created.\n9. Click \\*\\*Keys\\*\\*.\n10. Click \\*\\*Add key\\*\\*, then click \\*\\*Create new key\\*\\*.\n11. For \\*\\*Key type\\*\\*, select \\*\\*JSON\\*\\*.\n12. Click **Create** and the private key downloads to your computer.\n13. Click \\*\\*Close\\*\\*.\n14. Move the file to your working directory and rename it `service_account_key.json`.\n\n| **Warning:** Service account keys can become a security risk if not managed carefully. For advice see [best practices for managing API keys](https://cloud.google.com/iam/docs/best-practices-for-managing-service-account-keys).\n\nStep 2: Prepare the project\n---------------------------\n\n1. Create a new .NET Core C# *Console Application* project in Visual Studio.\n2. Open the Package Manager, select the package source **nuget.org** , and add the following packages:\n - `Google.Apis.AndroidProvisioningPartner.v1`\n - `Google.Apis.Auth`\n\nTo learn more, read the Microsoft document [Install and use a\npackage](https://docs.microsoft.com/en-us/nuget/quickstart/use-a-package).\n\nStep 3: Set up the sample\n-------------------------\n\n1. Drag the `service_account_key.json` you downloaded when you created your service account into your Visual Studio Solution Explorer.\n2. Select `service_account_key.json`, and then go to the Properties window and set **Copy to output directory** field to *Always copy*.\n3. Replace the contents of `Program.cs` with the following code:\n\n```c#\nusing Google.Apis.AndroidProvisioningPartner.v1;\nusing Google.Apis.AndroidProvisioningPartner.v1.Data;\nusing Google.Apis.Auth.OAuth2;\nusing Google.Apis.Services;\nusing System;\nusing System.Collections.Generic;\nusing System.IO;\nusing System.Threading;\n\nnamespace ZeroTouchCustomerQuickstart\n{\n class Program\n {\n // A single scope is used for the zero-touch enrollment customer API.\n static readonly string[] Scopes =\n { \"https://www.googleapis.com/auth/androidworkzerotouchemm\" };\n static string ApplicationName = \"Zero-touch Enrollment .NET Quickstart\";\n\n static void Main(string[] args)\n {\n GoogleCredential credential;\n\n // Authenticate using the service account key\n credential = GoogleCredential.FromFile(\"service_account_key.json\")\n .CreateScoped(Scopes);\n\n // Create a zero-touch enrollment API service endpoint.\n var service = new AndroidProvisioningPartnerService(new BaseClientService.Initializer\n {\n HttpClientInitializer = credential,\n ApplicationName = ApplicationName\n });\n\n // Get the customer's account. Because a customer might have more\n // than one, limit the results to the first account found.\n CustomersResource.ListRequest accountRequest = service.Customers.List();\n accountRequest.PageSize = 1;\n CustomerListCustomersResponse accountResponse = accountRequest.Execute();\n if (accountResponse.Customers.Count == 0)\n {\n // No accounts found for the user. Confirm the Google Account\n // that authorizes the request can access the zero-touch portal.\n Console.WriteLine(\"No zero-touch enrollment account found.\");\n Environment.Exit(-1);\n }\n Company customer = accountResponse.Customers[0];\n var customerAccount = String.Format(\"customers/{0}\", customer.CompanyId);\n\n\n // Send an API request to list all the DPCs available.\n CustomersResource.DpcsResource.ListRequest request = service.Customers.Dpcs.\n List(customerAccount);\n CustomerListDpcsResponse response = request.Execute();\n\n // Print out the details of each DPC.\n IList\u003cDpc\u003e dpcs = response.Dpcs;\n foreach (Dpc dpcApp in dpcs)\n {\n Console.WriteLine(\"Name:{0} APK:{1}\",\n dpcApp.DpcName,\n dpcApp.PackageName);\n }\n\n }\n }\n}\n```\n\nStep 4: Run the sample\n----------------------\n\nTo build and run the sample, click play_arrow **Start** in the Visual Studio toolbar.\n\nNotes\n-----\n\n- Avoid sharing your `service_account_key.json` file with anyone. Be careful not to include it in source code repositories. You can read more advice on [handling service account secrets](https://cloud.google.com/iam/docs/best-practices-for-managing-service-account-keys).\n\nLearn more\n----------\n\n- [Google Developers Console help documentation](/console/help/new)\n- [Google API Client Library for .NET\n documentation](/api-client-library/dotnet)"]]
