.NET 6 Preview 5 MAUI App 體驗使用經驗 1

2021 年 6 月 17 日，微軟發表的 .NET 6 Preview 5 ， Announcing .NET 6 Preview 5 ，所以，這篇文章將會來驗看看有那些新功能與不錯的特色推出。

為了要能夠輕鬆的進行使用 .NET 6 Preview 5 這個系統，特別重新安裝作業系統到最新的 Windows Updates，接著安裝 Visual Studio 2019 Preview 工具，並使用 Download .NET 6.0 文章來進行安裝最新的 .NET 6.0 Preview 5 相關軟體。

為了要能夠順利建立專案等環境，這裡還需要安裝兩個 Visual Studio 擴充功能 Project Reunion (Preview) 與 Single-project MSIX Packaging Tools ，這裡將會安裝 Windows UI Library (WinUI) 開發環境到 Visual Studio 內。

以上的準備工作若都完成後，將會根據 Announcing .NET MAUI Preview 5 與 .NET Multi-platform App UI documentation 文章來進行 Maui 的安裝與設定

安裝與檢查 Maui 是否完整

為了要驗證 Maui 開發環境是否完整，可以透過底下的程序來進行檢查是否欠缺甚麼元件尚未安裝，或者需要進行升級。

首先安裝 maui-check 這個工具，這裡可以透過底下的指令來完成，請在命令提示字元視窗內執行這個指令

dotnet tool install -g redth.net.maui.check

一旦安裝完成之後，就可以執行 [maui-check] 指令，請在命令提示字元視窗內執行這個指令

maui-check

在作者本身的環境為全新安裝的 Windows 10 作業系統，並且升級到最新 Windows Update，接著安裝 Visual Studio 2019 Preview 版本，並選取了需要用到的 [工作負載]；而當執行了 maui-check 指令之後，會出現文章最後面所列出的相關內容，不過，在這裡檢查出底下的問題，這些問題應該是安裝好工具之後，尚未做相關的初始化設定所導致的，不過，因為 maui-check 的幫忙，可以順利修正這些問題

? Recommendation: Install OpenJDK11
在這裡將會發現預設 Android SDK 安裝好之後，沒有使用 [Microsoft OpenJDK]，因此，將會詢問是否要更換使用 [OpenJDK] 呢？在這裡將會回答 Yes，使用 [OpenJDK] 來替換

? Recommendation: Install or Update Android SDK packages
接下來則是發現到 Android SDK 預設安裝後，並不是最新的版本，因此將會建議來更新到最新版本，或者安裝尚未發現到的 SDK 軟體，在這裡回答 Yes

Your Android SDK has missing or outdated packages.
You can use the Android SDK Manager to install / update them.
