升級到Xamarin Forms 2.0後出現Android資源問題

Question

我最近將2臺機器從Xamarin Forms 1.x升級到了2.0。一臺機器可以，Xamarin Forms項目可以爲Android構建好。另一臺機器有可怕的問題。

我們嘗試卸載並重新安裝所有東西 - Xamarin，Android SDK，所有NuGet包 - 很多 - 但獲取相同的錯誤消息。

它似乎與Android應用程序compat東西有關。

步驟複製是：

1. 創建新表單1.3項目 - 編譯和運行 - 從表格1.3至2.0都可以
2. 升級項目 - 發出

下面是錯誤的：

Answer 1

刪除Resource.Designer.cs文件中的所有內容（不是itsel文件f）重建。它應該爲您重新生成文件，錯誤將會消失。

首先下一步

確保您的谷歌支持包都在23.0.1.3。這是對XF 2.0的要求，但它們應該已經通過XF 2.0升級進行了更新。

當一切都失敗（跨複製從我的回答另一個問題）

1. Clean solution 
2. update-package -reinstall (can use -project just for your Android project) 
3. Delete Resource.Designer.cs contents again 
4. Restart Visual Studio 
5. Rebuild once again 

你也可能要添加哭泣，祈禱或與那些步驟:)

一個在咒罵最後一件事情，如果這不起作用，請再次嘗試，但這次卸載所有NuGet軟件包和組件，而不是重新安裝。之前這對我有效。然後確保你的緩存是乾淨的（C：\ Users \ yourusername \ AppData \ Local \ Xamarin）。我通常會刪除這裏的所有內容，以便重建它們。

不幸的是，我必須做上面列出的所有事情才能讓Resource.Designer.cs在以前的場合工作。
