c# - 使用 Xamarin Forms 在 Visual Studio 中创建 Hello World 失败

Question

我引用了这个解决方案/问题 The type or namespace name 'Xamarin' missing in xamarin studio

但是仍然无法从新的通用应用程序项目向导构建应用程序。

Severity    Code    Description Project File    Line    Suppression State
Error   CS0117  'Resource.Attribute' does not contain a definition for 'actionBarSize'  
Project.Droid   C:\dev\Project.Droid\Resources\Resource.Designer.cs 29  Active

Xamarin 新手有什么想法吗？

好的，这就是答案!我有一个本地复制品，似乎 .csproj 中缺少一些引用:

请确保将以下内容添加到您的 .csproj 作为引用:

<Reference Include="Xamarin.Android.Support.Design, Version=1.0.0.0, Culture=neutral, processorArchitecture=MSIL">
  <HintPath>..\..\packages\Xamarin.Android.Support.Design.23.0.1.3\lib\MonoAndroid403\Xamarin.Android.Support.Design.dll</HintPath>
  <Private>True</Private>
</Reference>

然后您可以从您的项目中删除 Resource.designer.cs 文件，重建您的项目，然后将 Resource.designer.cs 文件重新添加到您的项目。它应该生成以下 Attribute 项:https://gist.github.com/JonDouglas/7adf61469ce21663d7f536a4aa27c7df
