我一直在使用Xamarin開發一個android應用程序。直到今天，我一直在努力更新Xamarin和Android SDK，並且突然間我收到以下錯誤消息：初始化任務PropertyGroup時出錯：未註冊的任務PropertyGroup
「初始化任務PropertyGroup時出錯：未註冊的任務PropertyGroup。」

你有一個堆棧跟蹤或截圖或東西，顯示你在哪裏得到的消息？ – Cheesebaron
這是當我嘗試編譯該項目。我可能應該說我也參考了便攜式庫，不知道這是否重要。 – ThisAndThat
您可以嘗試在Android Library Project中鏈接您的文件，並查看是否可以解決問題，PCL的工作對我來說可以，但Reflection有一些問題。因此它不應該是錯誤的地方。我認爲PropertyGroup引用了csproj文件中的某些內容，其中包含項目和屬性組，可以發佈錯誤的屏幕截圖並將您的csproj文件發佈到此處？ – Cheesebaron
