AzureAIClientProvider not working with API Key

[dehlers-cts]

The AzureAzureClientProvider works correctly if it is using a DefaultAzureCredentals. However, if I want to use an API Key instead, it returns http 401 Unauthorized.

// Use connection string and API key
if (azureOpenAISettings?.ConnectionString != null && azureOpenAISettings?.ApiKey != null)
{
try
{
// Create a TokenCredential using the API key
var apiKeyCredential = new ApiKeyTokenCredential(azureOpenAISettings.ApiKey);

    // Create the client provider using connection string and API key credential
    AzureAIClientProvider clientProvider = AzureAIClientProvider.FromConnectionString(azureOpenAISettings.ConnectionString, apiKeyCredential);
    
    // Get the agents client
    _client = clientProvider.Client.GetAgentsClient();
    
    // Set the flag - we'll create the agent and thread when needed
    _isInitialized = true;
}
catch(Exception ex)
{
    Console.WriteLine($"Failed to initialize Azure AI Agent client: {ex.Message}");
    throw;
}

I don't see anyway to use an api key. Is there a way to connect to the Azure AI Foundry Agent with an api key? It looks like the only way is with a credential. I am using an Azure Government SQL Server database and a Commercial Azure AI Foundry Agent. I can't use the same credentials. I could change the SQL Server to use a username and password but I should be able to use an API Key instead of the AzureDefaultCredentials.

Foundry does not support the use of API key to connect to a Foundry Project.
