A guy on Upwork made an app for me using this design pattern. I have to make updates and trying to figure out how it works. With events, at least you know where to look to see what a button does. This design pattern seems cool, but good luck trying to figure out how anything works if someone else made it

Really awesome tutorial! Thank you! I had to make a dynamic screen with controls based on the datatype of the parameters... Your technique worked like a charm. Thank you!

Getting a "can't put a window in a style" error on the <view: View/> lines in the mainwindow.xaml ?

The method you showed in the video seems not to work on Android using .NET Core 8.0. When I initialize Serilog as you showed, no log file is created and nothing is logged. using Microsoft.Extensions.Logging; using Serilog; namespace MauiApp2 { public static class MauiProgram { public static MauiApp CreateMauiApp() { var builder = MauiApp.CreateBuilder(); builder .UseMauiApp<App>() .ConfigureFonts(fonts => { fonts.AddFont("OpenSans-Regular.ttf", "OpenSansRegular"); fonts.AddFont("OpenSans-Semibold.ttf", "OpenSansSemibold"); }); // This seems not to work on Android using .NET Core 8.0 builder.Services.AddSerilog(new LoggerConfiguration() .MinimumLevel.Verbose() .Enrich.FromLogContext() .WriteTo.Debug() .WriteTo.File(path: Path.Combine(FileSystem.Current.AppDataDirectory, "logs", "AppLog-.log"), rollingInterval: RollingInterval.Day, rollOnFileSizeLimit: true, retainedFileCountLimit: 31) .CreateLogger()); return builder.Build(); } } } However, the following initialization works on Android using .NET Core 8.0: using Microsoft.Extensions.Logging; using Serilog; namespace MauiApp2 { public static class MauiProgram { public static MauiApp CreateMauiApp() { var builder = MauiApp.CreateBuilder(); builder .UseMauiApp<App>() .ConfigureFonts(fonts => { fonts.AddFont("OpenSans-Regular.ttf", "OpenSansRegular"); fonts.AddFont("OpenSans-Semibold.ttf", "OpenSansSemibold"); }); // This works on Android using .NET Core 8.0 Log.Logger = new LoggerConfiguration() .MinimumLevel.Verbose() .Enrich.FromLogContext() .WriteTo.Debug() .WriteTo.File(path: Path.Combine(FileSystem.Current.AppDataDirectory, "logs", "AppLog-.log"), rollingInterval: RollingInterval.Day, rollOnFileSizeLimit: true, retainedFileCountLimit: 31) .CreateLogger(); builder.Services.AddSerilog(Log.Logger); return builder.Build(); } } }

great tutorial but the naming scheme gives me headache

one word, awesome.

you could just not talk about steps you take, instead of skipping them. Sorry to say but even if you watch yourself your own video, you'll find it frustrating.

I just have a suggestion to set "Follow Active Document in Solution Explorer" config setting to true so when you change tabs we can see where the file is located in the solution. It might be helpful for some viewers like myself. Great video.

nice work bud, keep it goin' kıps

Alot of videos explain the factory for deciding which type of object to instantiate. This one also shows how to handle dependencies. This is a must use when using a DI container, making it very easy to add a service to the factory (injected with DI container) which will be communicated to the service. Hope that makes sense... Thanks for the video.

Get ready for everyone's pc to flag your app as a virus

4:43 If you don't put some parameter or logic for the creation of the instance the lambda expression is innecesary I think (newbie here :p) services.AddTransient<PeopleListingViewModel>(s => new PeopleListingViewModel());

Thanks for the great tutorial

is there a way to download your code?

Use react native with expo. Maui is terrible with memory leaks everwhere with complex layouts, your apps will just crash without reasons. Memory leaks embedded within MAUI, MS doesn't even use MAUI on their OWN FLAGSHIP products as they are not possible in .net MAUI. MS will cancel and abandon it. Migrate all apps to react native with expo as that is the future. Better tooling, easier to use, no memory leaks, can customize everything, way faster.

Your series of videos is very good, thanks for the effort!

Not anymore. .Net 9 MAUI updates have been very stable and even better .Net ASPIRE as my backend helper framework in Azure has made my experience much better. I can build all my APIs, using Google Firebase for Auth (front end and backend to Azure), using SyncFusion UI, I’ve been able to build amazing apps. Even one I’m now about to publish using PLAID. I’ve been able to still continue (as I have with Xamarin) building both Android and iOS apps pretty damn easy and bug free. With very scalable Azure app services, SQL server, message queuing, storage, and security through managed identities and OAuth. I think if you really know the framework you’re fine. Easy to work through the quirks.

simple: MS user RN

Excellent !

This is pure GOLD!

Very helpful series, great job!

@SingletonSean What differences would I run into if I used, for example, Supabase instead of Firebase? Are there any large differences between them?

Awesome video!

---------------_-_-_-_-_---------- What is in program.cs show that page

How you doing man? last video seems quite outdated. any good, it would be great if I get your new video!

I am currently building a .NET MAUI Hybrid app. It's amazing.

Thanks, good stuff

I deleted StartUpUri and now styles are not applied. How to fix this?

Well explained to someone who is good at c#, but for someone who is learning, this is just too fast, I know you are good at your work, but you aren't proving me how fast you can do it, you are literally teaching me something.

I am impressed by the way you think and just code it , how can i become pro like you ? :)

why do you re-create the view models again and again?

Hi Sean, I watched your videos on using Strawberry Shake with GraphQL and found it really helpful! I have a quick question: How can I access response headers with Strawberry Shake? Is there a specific configuration or approach to intercept them? I’d really appreciate any guidance :)

Man, you are going too fast

Perfect, thank you!

Nice video! Would you like an easy way to find your actual database after the app creates it? I print the complete file path to the console. From there, I copy/paste the path into my file browser. I recommend using a Sqlite editor such as Navicat For Sqlite or JetBrains DataGrip to open and examine your database so you can verify that the app is doing what is expected.

Making my notes in the comment section: ViewModals used: 1. KZbinViewersDetailsViewModel : The right pane 2. KZbinViewersListingViewModel : The whole list in the left pane 3. KZbinViewersListingItemViewModel : It is each tab in list (left pane) consisting of username and commands under 3 dots 4. KZbinViewersViewModel : where above 3 VMs are instantiated

I'm just starting to discover MAUI. So I'm not an expert, but it seemes good to me. Not so bugged as portraied. Generally if you follow the guide lines it works well... bugs are everywhere on any framework. What I think is good of MAUI is the intention to be wide spread usable. I think MAUI is just at the beginning, like the .NET framework itself initially wasn't so good, and then it spread everywhere. And xaml is a very good feature since you can take almost any previous application and keep the UI (like from WPF for example). The fact is that the platform zoo is so vast and various, so give them some time. I'm confident it will be good.

Man i didnt work for me..I did every step. I dont get any value into the variabel(key). creaed json file -> created AddAppsettings method -> downloaded 2x nugets (Bind & Json) -> changed propertie of json file. builder.AddAppSettings(); string key = builder.Configuration.GetValue<string>("ID_KEY"); private static void AddAppSettings(this MauiAppBuilder builder) { using Stream stream = Assembly .GetExecutingAssembly() .GetManifestResourceStream("VerifyIdentityProject.appsettings.json"); if(stream != null) { IConfigurationRoot config = new ConfigurationBuilder() .AddJsonStream(stream) .Build(); builder.Configuration.AddConfiguration(config); } }

Code snippets that are already part of visual studio only require one tab button press, however the custom snippets require two. Is there anyone way to change that behavior and only require that my custom snippet needs one tab button press?

Not sure if you still watch these comments, but I hope you do :D I'm very confused about what benefit this provides. It seems like you're adding a lot of boilerplate to solve something that was never a problem. I see IoC containers and ServiceProvider patterns being considered best-practices in several domains, but every time I've ever wrestled with a system that uses them it just feels like an exercise in frustration. When things are not done perfectly, you get opaque errors. When things are done right, you have a bunch of indirect references to global shared state which makes the tracking down problems more difficult. I've heard people say they help with testing, but I've never seen a convincing argument for it. How is this better than just using normal constructors and passing around references?

Singleton Sean, my man. I will appear to you in your moment of greatest peril to repay this debt.

Thank you Sean, very based.

Hi Sean, I have devoured all your playlists on WPF. I'm a regular subscriber and find your videos really great. I have learned a lot about the MVVM model and your instructions are very practical. With the ParameterNavigationService feature, however, I fail at the implementation via DependencyInjection. You only implemented this in another installment of this series, but unfortunately no longer have an example in your application on GitHub. You have created an example for iancarr3923 that shows the normal implementation, but I always fail to pass the parameter via DependencyInjection. Since I would like to use the feature in a current project, I would be very grateful for a tip. Otherwise I can only encourage you: Keep up the good work.

Great videos, but man you go fast. I usually watch videos at 1.25 or 1.5x, but you're the first person who seems too fast for me even at normal speed! Great content though, very helpful.

great video & tutorial!! small note for 2024: the [Service] attribute isn't necessary and in fact will break the batch loading functionality 😊

Now... a year after... there is hope? Blazor (Even MS use it) Aspire (Literaly You work for MS without contract) Core (Same as Aspire) MAUI: - It has no maps support - Binding libraries doesn't work - Lack of Doc and Benchmarks - No good examples and code snipets & tutorials - No Dev friendly at all The 'stuff' with MAUI, it's that customers want interconnected apps (desktop, web, Mobile & Excel obviously)

Your videos are great, I've learned a lot about WPF. May I ask why did you make a field public (3:46)? I heard it's a bad practice. Thanks!

Views are garbage collected but viewmodels must be explicitly disposed. Set all fields and events to null (especially PropertyChanged) because hidden view objects that retain mystery bindings will be your biggest source of memory leaks. And viewmodels will be hard to manage unless you give them a parent-child relationship just like the visual and logical trees. Destructors don't come into play with viewmodels because viewmodels should only be used and disposed on the Dispatcher they were created from.

Love the series, at 10:13 how did you inspect the actual network connection made between refit and the api? Where did you get the header information from?
