QUESTION
I need for exceptions thrown within a timed event to be bubbled up and handled outside of the event handler context. I had read that System.Threading.Timers would be able to do that, provided that, as outlined in the answer to this question, the exception is caught in the callback method and a mechanism is used to re-throw it. Using this example as a guide, I created an event handler which throws and a method which should catch and re-throw the exception using an IProgress object:
ANSWER
Answered 2022-Mar-23 at 15:59I'm guessing ThrowerThreaded is running on a background thread. That means it does not have a synchronizationContext, since these are intended to synchronize UI applications. This means the callback is called on the threadpool:
Any handler provided to the constructor or event handlers registered with the ProgressChanged event are invoked through a SynchronizationContext instance captured when the instance is constructed. If there is no current SynchronizationContext at the time of construction, the callbacks will be invoked on the ThreadPool.
Rethrowing the exception on a threadpool thread will probably kill that thread, and I'm somewhat surprised it did not kill the application, but it's possible that such behavior is overridden by the testing framework you are using.
To solve this you really need to handle the exception in the callback instead of re-throwing it. If you are not handling the exception, who should? there is a unhandledExceptionEvent, but that is intended for logging before you close your app.
You could handle the exception taking a callback in ThrowerThreaded that you delegate the exception handling to. Another alternative would be to create a TaskCompletionSource that allow you to return a task, and set the task to 'failed' by calling SetException on the source.
It is also poor practice to re-throw the same exception object, since you will lose the call stack, you should instead wrap the exception in a new exception that is thrown.

I've got a repository interface (simplified example code):
...ANSWER
Answered 2022-Feb-20 at 18:04Oversimplifying this, you basically have 2 options: having a consistent interface or not.
There are, of course other design patterns which might work here, (e.g.; some decorators and a factory method), but I believe them to be overkill.
If you stick to the general rule that consistent interface is desired, I think having a "not entirely implemented" callback technique isn't that bad. You could also consider just to implement it - or at least: make it return something which makes sense.
I would definitely avoid a construction with 2 different interfaces of some kind. Although sometimes this is the better option (when checking if something supports something), e.g.; testing if a hardware component is available - I see it as overkill in your scenario. It would also put more logic at the caller side, and unless you want to open a process-dialog screen only in this scenario, I would avoid it.
A last note: there are alternative progress report patterns such as using an event, or, passing in an optional callback method. This latter looks like your solution but is in fact a little different.
Still this faces you with the same issue in the end, but might be worth to consider.
There are many more solutions - but given the context you provided, I am not sure if they apply. And keep in mind, this is highly opinion based.
QUESTION
I would like to know the difference between using EventHandler and Progress. Are there any situations in which one is a better choice?
When dealing with async Tasks I often see an EventHandler progressChangedCallback that people use to subscribe to a ProgressChanged event of an object and report progress change to e.g. a progress bar on the UI. I also see people passing IProgress instances to the Tasks as parameters. The difference is that they don't invoke an event, they call the IProgress.Report() method instead.
ANSWER
Answered 2022-Feb-11 at 08:47They're different mechanisms. An event is defined on a class, and a IProgress is passed to the async operation itself. An event might make more sense when only 1 async operation is happening at a time, and the progress of every such operation needs to be displayed in the same way, as the UI needs to subscribe to a single event once, and all progress updates from it are handled the same way. An IProgress might make more sense when you can have multiple async operations on the go at once, as it lets you understand which progress is being reported by which operation.
Note that the Progress does the nice thing of dispatching progress updates back to the UI thread (if used in the right way), but events don't do this.

ANSWER
Answered 2021-Dec-18 at 00:55It sounds like your package simply isn't being loaded. Packages in VS are not loaded until something indicates that they should be; this can either be an explicit call from some other code to tell the VS shell to load your package, or by specifying an automatic loading rule.
See the documentation for details.

QUESTION
I am trying to figure out how to update a progress dialog box from a separate ViewModel. This is my first full C# application, and in actuality, my first application. I have been stuck on this particular issue for a couple of days now, and feel that I have tried to approach it from a couple of different angles, but with no success.
Let's start with a brief overview: This application will be used by myself and my team to assist in staging PC's for deployment in the field. It starts with a very simple UI where the staging tech will select the site ID from a list and then click on "Configure" to start the process. The rest of the process will not require any user interaction.
I am trying to have a progress dialog box appear on top of the initial UI to give the tech an indication of the progress.
At the moment, I am able to get the progress box to appear, but am not able to update it.
Here is the code for the ShellViewModel:

Initially, I was trying to use Progress() and IProgress, which isn't the way you do it in Caliburn Micro. It's done through event aggregation. I just had to work through how and where to call the event. Thanks to @Demon for pointing me in the right direction on that.

Install IProgress
You can use IProgress like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
