I'm trying to test first in Visual Studio.

For now using Azure Key Vault references with Azure Functions does not support to work on local, as confirmed by Azure Functions team. If you still want to test on local, you could implemented an incomplete local workaround like this issue.

I test on portal and it works well. You could refer to the following steps as below：

1.In VS Function.cs, then publish to azure：

 public static void Run([QueueTrigger("queue", Connection = "AzureWebJobsStorage")]string myQueueItem, TraceWriter log)
 {
     log.Info($"C# Queue trigger function processed: {myQueueItem}");
     string connectionString = System.Environment.GetEnvironmentVariable("AzureWebJobsStorage");
     log.Info($"The connection string is {connectionString}");
 }

2.Set AzureWebJobsStorage on Appsettings setting on portal.

3.Then it will work fine.
