In this video we perform a full step by step build of a .NET MAUI App that we test on both Windows and Android. The app interacts with a separate .NET 6 API that we also build step by step.

نکته ای که در مورد ماژول‌های native وجود دارد این هست که این ماژول‌ها دسترسی بدون محدودیتی به منابع سروری دارند و از این رو حتما باید این نکته را دقت کنید که ماژول native شما از یک منبع مورد اعتماد دریافت شده باشد.

%windir%\system32\inetsrv\config\applicationhost.config

کسی که نیاز به دسترسی به این مسیر و انجام تغییرات دارد باید در بالاترین سطح مدیریتی سرور باشد.

In .NET 8 we plan to add a new project template, Blazor Web Application, that covers all combinations of server-hosted projects (traditional Blazor Server apps, Blazor WebAssembly hosted, and the new unified architecture that allows use of Server, WebAssembly, and SSR in a single project). It will work by multitargeting over net8.0 and net8.0-browser.
