Sample: Simplified connection quick start using Microsoft Dataverse

  • Article

This C# .NET sample shows how to connect to the Microsoft Dataverse web service using the CrmServiceClient class and a connection string. The sample then perform create, update, retrieve, and delete operations on a Dataverse table. For more information about the CrmServiceClient see Use CrmServiceClient constructors to connect to Dataverse.

Note

You could also use the ServiceClient instead of the CrmServiceClient class in this sample.

Requirements

  • Visual Studio 2019 or later
  • Dataverse test environment and valid user logon credentials

How to run the sample

  1. Clone the PowerApps-Samples repository so that you have a copy locally.
  2. Open the dataverse\Xrm Tooling\QuickStartCS\C#\QuickStartCS.sln file in Visual Studio.
  3. In Solution Explorer, modify the App.config file with connection information for your Dataverse instance before running the sample. See the example App.config below.
  4. Press F5 to compile and run the program.

Demonstrates

This sample authenticates the user with Dataverse web services by using a connection string passed to the CrmServiceClient class.

After obtaining a reference to the Organization web service, the sample performs create, update, retrieve, and delete operations on an account table. The sample also handles common exceptions.

In addition, this sample supports OAuth authentication and advanced connection diagnostics that is configured in the App.config file. For more information on using diagnostics, see Configure tracing for XRM Tooling.

Example App.config

The following shows a sample app.config file. To use this, remove the comment characters “<!- -” at the beginning of the <add name=… /> line and the “- ->” at the end on the line within the connectionStrings XML tags. Next, modify the connection string username, url, and password values as appropriate for your Dataverse test environment.

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <connectionStrings>

  <!--<add name="Connect"
  connectionString="
  AuthType=OAuth;
  Username=jsmith@contoso.onmicrosoft.com;

  Password=passcode;
  AppId=51f81489-12ee-4a9e-aaae-a2591f45987d;

  </connectionStrings>
</configuration>
