QUESTION
I'm migrating a servicebus client application from Microsoft.Azure.ServiceBus to use the current library Azure.Messaging.ServiceBus.
The application is a Worker Process running on a virtual machine in windows azure.
The VM has a system assigned managed identity which grants it access to service bus and we have been using it successfully with the old library for over a year.
On the old library we created a client using this connection string
Endpoint=sb://MyNamespace.servicebus.windows.net/;Authentication=Managed Identity
When I put that connection string into the constructor of Azure.Messaging.ServiceBus.ServiceBusClient I get the following error
...ANSWER
Answered 2022-Mar-29 at 12:23The clients in the Azure.Messaging.ServiceBus
package support connection strings only in the format that the Azure portal returns them.
The ;Authentication=Managed Identity
token that you've included in your connection string is not a known token and is ignored, so the client does not have the information needed to perform authorization. A managed identity cannot be specified via connection string.
To use a managed identity, you'll use one of the constructor overloads that accepts a fully qualified namespace and a TokenCredential
. An example can be found in the package Overview docs. Any of the Azure.Identity credentials can be used; you may want to take take a look at the managed identity section of the Azure.Identity
overview.

See code below ##If user inputs %100 or a100 or non-numeric value for temp, I need to display "Error: You must enter a numeric Value!" Write-host $("Error: You must enter a numeric Value!") ## then goes back to start ##im guessing if ($value isnot [int]) or something like that for it to work. thank you. ##Error I get without proper coding......What is the temperature in Fahrenheit: a111 ##Cannot convert value "a111" to type "System. Single". Error: "Input string was not in a ##correct format."
...ANSWER
Answered 2022-Mar-02 at 14:14There is much redundant code on your script which could be simplified, the biggest issue is the use of $input
which is an automatic variable and should not be assigned manually. As for the formula to convert from Fahrenheit to Celsius, you could use a function for that, as aside, according to Google, the formula should be (X − 32) × 5 / 9
though I'm not an expert on this, feel free to change for whatever you like.
QUESTION
Som I'm currently looking into updating our very simple service bus service to the latest version (Asure.Messaging.Servicebus) and I'm running into a smaller problem here.
The thing is I want to complete or abandon received or peaked messages manually by delegating the message back to methods in my service class to handle the job.
Here is my simple class so far, exposed by an interface.
...ANSWER
Answered 2022-Feb-17 at 14:57Service Bus associates a message lock with the AMQP link from which the message was received. For the SDK, this means that you must settle the message with the same ServiceBusReceiver
instance that you used to receive it.
In your code, you're creating a new receiver for ReceiveMessage
call - so when you attempt to complete or abandon the message, you're using a link for which the message is not valid if any other call to ReceiveMessage
has taken place.
Generally, you want to avoid the pattern of creating short-lived Service Bus client objects. They're intended to be long-lived and reused over the lifetime of the application. In your code, you're also implicitly abandoning the senders/receivers without closing them. This is going to orphan the AMQP link until the service force-closes it for being idle after 20 minutes.
I'd recommend pooling your senders/receivers and keeping each as a singleton for the associated queue. Each call to SendMessage
or ReceiveMessage
should for a given queue should use the same sender/receiver instance.
When your application closes, be sure to close or dispose the ServiceBusClient
, which will ensure that all of its child senders/receivers are also cleaned up appropriately.
I'd also very strongly recommend refactoring your class to be async. The sync-over-async pattern that you're using is going to put additional pressure on the thread pool and is likely to result in thread starvation and/or deadlocks under load.
UPDATE
To add some additional context, I'd advise not wrapping Service Bus operations but, instead, have a factory that focuses on managing clients and letting callers interact directly with them.
This ensures that clients are pooled and their lifetimes are managed correctly, while also giving flexibility to callers to hold onto the sender/receiver reference and use for multiple operations rather than paying the cost to retrieve it.
As an example, the following is a simple factory class that you'd create and manage as a singleton in your application. Callers are able to request a sender/receiver for a specific queue/topic/subscription and they'll be created as needed and then pooled for reuse.

Answered 2022-Feb-01 at 21:17The pet rock named Steven is not a direct child of myDataObject, so you can't delete it like that. You can loop through the "data" array, rebuilding the "pet-rocks" array for each element. A simple filter to remove any pet rocks named Steven should work.
