Connecting to DataStax Astra


Use the Builder.WithCloudSecureConnectionBundle(string path) method to connect to your DataStax Astra database using your secure connection bundle (

Also, use Builder.WithCredentials(string username, string password) to provide your CQL credentials.

Here is an example of the minimum configuration needed to connect to your DataStax Astra database using the secure connection bundle:

var session = 
           .WithCredentials("user_name", "password")

Supported platforms

DataStax Apollo support on .NET Core requires .NET Core Runtime 2.1 or later.

For the remaining platforms supported by the driver, there is no additional requirement.

Configurable settings when using a secure connection bundle

The following methods will throw an error when .Build() is called if the secure connection bundle is used:

  • Builder.WithSSL(...)
  • Builder.AddContactPoint(...) and Builder.AddContactPoints(...)

Every other method in the Builder class will have the same effect whether you are using a secure connection bundle or not.

Minimal example project

You can find a minimal .NET Core Console Application project in the examples folder of the driver’s Github Repository.
