[BUG] Can't authenticate using AZ CLI with Kusto on MacOS (System.PlatformNotSupportedException: Az-Cli does not support the current operting system)

Library name and version

Kusto.Data 11.0

Describe the bug

I’m facing an issue when trying to authenticate to my ADX cluster in a local C# Azure function using AZ CLI Authentication on MacOS:

Error : System.PlatformNotSupportedException: Az-Cli does not support the current operting system

Am I missing something? Has the Kusto C# SDK not delivered this feature yet? TIA

Expected behavior

I expected it to behave in the same fashion as in Python. To use the AZ CLI to authenticate with Azure services.

Actual behavior

It’s saying that my current platform (MacOS) is not supported yet. However I find that hard to believe because it works for the Python SDK.

Reproduction Steps

Here’s the code:

public static class QueryParsingService
    {
        [FunctionName("QueryParsingService")]
        public static async Task<IActionResult> Run(
            [HttpTrigger(AuthorizationLevel.Function, "get", "post", Route = null)] HttpRequest req,
            ILogger log)
        {
            var cluster = System.Environment.GetEnvironmentVariable("CLUSTER_ENDPOINT");
            var connection = new KustoConnectionStringBuilder(cluster).WithAadAzCliAuthentication(); // here
            var server = new ServerSymbolLoader(connection);
           
            try
            {
                 var tableNames = await server.LoadDatabaseAsync("DBName", cluster,true); // the stacktrace points here but the object is instantiated above
            }
            catch (System.Exception err)
            {
                System.Console.WriteLine("Error : " + err);
            }
            responseMessage.Add("tables", "OK");

            return new OkObjectResult(responseMessage);
        }
