Migrate C# driver

Complete the following procedure to migrate your existing DataStax C# driver to a version that is capable of connecting to Astra databases created using DataStax Astra DB.

Prerequisites

Create a database using Astra DB.
Download the secure connect bundle to obtain connection credentials for your Astra DB database.
Get your Client ID and Client Secret by creating your application token for your username and password.

Alternatively, have a teammate provide access to their Astra database.

Procedure

Add the dependencies for the C# driver to your project.
- DataStax C# driver for Apache Cassandra
- DSE C# driver
dotnet add package CassandraCSharpDriver -v 3.15.0
dotnet add package Dse -v 3.15.0

In your existing DataStax C# driver code, modify the connection code to use the Astra DB API.

Include the absolute path to the secure connect bundle for your Cassandra database (secure-connect-database_name.zip) in the WithCloudSecureConnectionBundle method call, and your credentials in the WithCredentials method call, as shown in the following examples.

DataStax C# driver for Apache Cassandra
DSE C# driver

var session =
  Cluster.Builder()
      .WithCloudSecureConnectionBundle(@"C:\path\to\secure-connect-database_name.zip")
        .WithCredentials("clientId", "clientSecret")
        .Build()
        .Connect();

var session =
  DseCluster.Builder()
      .WithCloudSecureConnectionBundle(@"C:\path\to\secure-connect-database_name.zip")
        .WithCredentials("clientId", "clientSecret")
        .Build()
        .Connect();

Run your application.
