.NET MAUI Preview 4 - 100% More Visual Studio & Blazor!

.NET 6 Preview 4 is here, which means .NET MAUI Preview 4 is here which features the first integrations into Visual Studio with the new single project system. Additionally, there is new support for C# hot reload, which is crazy exciting. On top of that there are new templates and support for .NET MAUI Blazor apps to create hybrid web, desktop, and mobile apps from a single codebase! I take it all on hands-on.

From a developer's point of view, C# Hot Reload is one of the coolest things the .NET team has done in years! Not going to lie, I geeked out for a second when you clicked "apply code changes" and it "just worked" on the app. So excited to not have to re-deploy my app every time I change the code-behind.

Can't wait till Maui is officially release

When will MAUI reach GA?
Definitely want to use it for all my apps.

In the old days from the city streets in the name of commercial premises appeared: hat shop, butcher shop, clothing store, .. nowadays everything is just logos.

The challenge of the programming genre is terminology. Everything is full of brand names and you need to know what it all means. A challenge to learning because you must first know the meaning of all the terms before you can study the subject. Important are working examples through which the topic can be learned. I really like folder names like fonts, images, resourses.. these terms have similar meaning in every platform.

Would be a good to do it from a developer point of view in terms of contributing. To the main branch?

[SamuelCarrier]

Cool to see some development! I still feel Xamarin isn't finish though. When can we expect to be able to do subscription and check if they are active in Ios and Android?

[Sonshapes]

Wow... looks great! What about deployment. Are we still stuck with Google/Apple store? And the Windows Desktop? Thx.

Do MAUI use native UI components with the handlers? I am confused if it is like Flutter with custom UI components or more like React Native that ties into the native UI API's

[dakoe]

James, can we use NuGet packages that we used in Xamarin Forms already? For example, Entity Framework, Newtonsonft.Josn, what about Xamarin Essentials? Thanks for your work

[cristisandu]

James, can you make a video with github actions and how to set on a xamarin forms project ?

[chuducminh]

I plan to develop a Cross-platform Desktop-app (for Windows and MacOS). More details: a Slack-like chat app. Do you think MAUI or Blazor will be more appropriate? (for better performance and interactive)

Hi
I have created a MAUI project in VS 2022 preview, which is working fine initially with emulator, but now Emulator is not showing. When I create Xamarin project Emulator is showing and application is running on that Emulator.

Please help me to resolve this issue as it occurs developing application

What I have tried:

1. I had delete/renamed
Copy Code




2. I had repair VS 2022 preview
3. I had reinstall MAUI

[sinsedrix]

No "Package" project visible, how can I get it?

[mattdhargett]

Can I do hot reloading on multiple android/iOS simulators (and a browser) on Mac? Will VS Mac eventually include a Windows/Xbox simulator so I can run some e2e tests on my Mac dev laptop before I publish an appx?

[DamagedDingo]

i installed preview and ran maui check but still can't see maui in dotnet new --list or in gui. anyone know why?

[codetayo]

James, I was also confused about that counter when I first tried the app. Why is that it resets to 1 after reaching 9?

Would be interested in knowing if anyone has gotten the Font Awesome icons to to work yet and if so How? I have been unable to get them to work yet. Tried looking int the Weather 21 sample because it it has a Font Awesome in the Font folder but I couldn't find anywhere in the app where it was used to display an icon.
