@JFulfordMS, can you provide more info like which of our packages you are using and what the version info is.

I'm using Azure.Data.AppConfiguration 1.4.1 and AzureAppConfiguration 7.2.0.

from appconfiguration.

@JFulfordMS please follow the document below for using App Configuration in Azure Functions.

@JFulfordMS

To help me make sure I understand what you're talking about, can you tell/show me how you get the Function to use a schedule defined in App Configuration?

from appconfiguration.

Sure, here is a way to test it. I set the parameter of "CdataHelper:Schedule" in an app configuration store to "*/30 * * * * *
". Then reference it in the TimerTrigger constructor. The function changes the value of the parameter to "*/5 * * * * *
" and successfully gets the updated value on the next run, but the timer still only runs every 30 seconds.

`

    private readonly IConfiguration _configuration;
    private readonly IConfigurationRefresher _configurationRefresher;
    private readonly ConfigurationClient configurationClient;

    public CdataJobFunctions(IConfiguration configuration, IConfigurationRefresherProvider refresherProvider)
    {
        _configuration = configuration;
        _configurationRefresher = refresherProvider.Refreshers.First();
        configurationClient = new ConfigurationClient(Environment.GetEnvironmentVariable("ConfigConnectionString"));
       
    }
    static HttpClient httpClient = new HttpClient();

    [FunctionName("DoUpdate")]
    public async Task Run([TimerTrigger("%CdataHelper:Schedule%")] TimerInfo myTimer, ILogger log)
    {

        log.LogInformation($"Running at: {DateTime.Now}");

        log.LogInformation(_configuration["CdataHelper:Schedule"]);
      
        var setting = configurationClient.SetConfigurationSetting("CdataHelper:Schedule", "*/5 * * * * *");
        await _configurationRefresher.TryRefreshAsync();

    }

The trigger uses the app setting binding expression of the Azure Functions. While your code can pick up the latest value in App Configuration, I suspect Azure Functions won't pick up the new setting without the function app being restarted (just like how app setting works in Azure Functions).
