✅ getting app to check repo for latest release, updating if versions don't match

I've created a help channel for this before, but at this point I'm lost. I'm wanting to set my app up so that when the user launches it, it runs a check to see if the user has the matching version to the latest github repo release. I am using Avalonia MVVM and I'm wanting to incorporate this into my Todo app first. https://github.com/mekasu0124/Todo The only problem is, I have no idea what file to do this in, or how to work with the github thing to achieve what I'm wanting to achieve. Thanks in advance

if I can get help learning how to do it in my Todo app, then I can replicate it and put it in my other apps on my own, I believe.

MainWindowView.axaml and MainWindowViewModel.cs dictates what is showing on the screen.

here, the MainWindowViewModel.cs obtains the list of items to display on the screen. I have a feeling that my update checker would happen in this file (likely calling an external class to do so) and either rendering the home screen like normal if the versions match, or rendering the "There is an update available, click ok to update" if the versions don't match. I just don't know how to implement that

You can use this API endpoint .

ok. I created a new file in my Services folder and named it Update.cs How can I use that endpoing api?

MMek ok. I created a new file in my Services folder and named it Update.cs How can I ...

Azrael•9/1/23, 3:32 AM

I can give you example.

MekOP•9/1/23, 3:32 AM

I appreciate it

Azrael•9/1/23, 3:33 AM

Azrael•9/1/23, 3:35 AM

That's all the syntax I know in my head from HttpClient.

Azrael•9/1/23, 3:37 AM

You can make the response string constant.

Angius•9/1/23, 3:38 AM

It'd be better to reuse a static instance of HttpClient and use maybe, but yeah, this looks fine

AAzrael ```cs private async Task DownloadUpdatesAsync() { using (var client = new Ht...

MekOP•9/1/23, 3:38 AM

I definitely appreciate it. My goal now is to take the examples you gave and make them working code. Once they're working code, I'll be building an file that I would like to have display when an update is available instead of the home screen

Angius•9/1/23, 3:38 AM

Question is, where to call it in the Avalonia app so that it runs on startup

Azrael•9/1/23, 3:38 AM

I wrote it in Discord :(

Angius•9/1/23, 3:38 AM

And shows a notification that the app is out of date

Azrael•9/1/23, 3:38 AM

Angius•9/1/23, 3:39 AM

Well, yes, sure

AAngius Question is, where to call it in the Avalonia app so that it runs on startup

Azrael•9/1/23, 3:39 AM

Good question, isn't there a base startup class?

MekOP•9/1/23, 3:42 AM

I can use MainWindowViewModel.cs to run the update checker, however, I have a problem

MekOP•9/1/23, 3:42 AM

how am I to define CurrentAppVersion? and what goes in ?

Angius•9/1/23, 3:44 AM

Also, just noticed that dependency

Angius•9/1/23, 3:44 AM

You'd define the version... somewhere

Angius•9/1/23, 3:45 AM

And would be how you get the version from the response you get from the API

Angius•9/1/23, 3:45 AM

So you'll need to either hit up the docs or call the endpoint with something like Insomnia, or even open it in the browser, to see where the version number is sitting

MekOP•9/1/23, 3:49 AM

MekOP•9/1/23, 3:49 AM

so here's where I'm at

MekOP•9/1/23, 3:49 AM

I've commented where the program will need to automatically know certain things. As far as CurrentAppVersion, the program will need to know that on it's own from the api call.

MekOP•9/1/23, 3:50 AM

so how can I do this?

MekOP•9/1/23, 3:51 AM

and to clarify, the boolean is for the program to know whether or not to show the usercontrol.

MekOP•9/1/23, 3:52 AM

and the variable is so that the usercontrol know to update the splash screen and when to close it

MekOP•9/1/23, 3:53 AM

the view that I'll be creating for this is a loading screen. It'll tell the user that an update is available and they'll click continue. When they click continue, it shows a progress bar that updates as the application is doing the update

MekOP•9/1/23, 3:53 AM

and the i'd like to programmtically get from the program without me having to manually update it

MekOP•9/1/23, 4:12 AM

I'm just not going to worry about it anymore. I can't figure this out, and it's really starting to frustrate me. Thanks for your help so far

TeBeCo•9/1/23, 4:16 AM

you want to get rid of that GetStringAsync and create a class

TeBeCo•9/1/23, 4:17 AM

and just GetFromJsonAsync

TeBeCo•9/1/23, 4:17 AM

remove the JObject newtonsoft crap

TeBeCo•9/1/23, 4:17 AM

remove the magic string

TeBeCo•9/1/23, 4:17 AM

var release = await httpClient.GetJsonAsync<YourReleaseClass>(........)

TeBeCo•9/1/23, 4:18 AM

release.PropGoesHere

MekOP•9/1/23, 4:22 AM

I got rid of all of it. I'm still really new to C# and avalonia in general. I"m great with axaml files because it's simliar to building a website and I picked that part up rather quickly. The C# part of it is really hard for me and I'm really new to it. I removed everything because half of what you said doesn't make sense to me. I'm not trying to annoy anyone or piss anyone off, but I need someone to teach me how to do this stuff. I cannot find any guides to do this with and the documentation I do find doesn't give any examples on what to do. I have tried using a regular console app to try and get information from the github as well, and I even fail at doing that, so at this point I'm just defeated. I either need someone to help teach me from step one until finished, or I'm just not going to waste my time with this language anymore. I'm spending more time trying to beg for help than actually getting it and I'm just over it

Angius•9/1/23, 4:24 AM

So, going to this link: https://api.github.com/repos/mekasu0124/Todo/releases/latest shows us some data about the latest release. We want to use that

Angius•9/1/23, 4:24 AM

We can take either as the version, or we can simply check the date

Angius•9/1/23, 4:25 AM

If either is higher than what we saved in the app during compilation, that means a new version exists
