升级到Xamarin Forms 2.0后，Android资源问题(Android Resource issues after upgrading to Xamarin Forms 2.0)
我最近将2台机器从Xamarin Forms 1.x升级到2.0。 一台机器没问题，Xamarin Forms项目适用于Android。 另一台机器有可怕的问题。
我们已经尝试卸载并重新安装所有内容 - Xamarin，Android SDK，所有NuGet软件包 - 很多 - 但是得到相同的错误消息。
它似乎与Android app compat相关。
复制的步骤是：
创建新的Forms 1.3项目 - 编译并运行 - 一切正常 将项目从Forms 1.3升级到2.0 - 问题以下是错误：

删除Resource.Designer.cs文件中的所有内容（不是文件本身）并重建。 它应该为您重新生成文件，错误将消失。
下一步
确保您的Google支持包全部为23.0.1.3。 这是XF 2.0的要求，但它们应该已经通过XF 2.0升级进行了更新。
当其他所有方法都失败时（从我对另一个问题的回答中复制）
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您可能还想添加抽泣，祈祷或诅咒这些步骤:)
最后一件事，如果不起作用，请再次尝试相同，但这次卸载所有NuGet包和组件而不是重新安装。 这之前对我有用。
然后确保您的缓存是干净的（C：\ Users \ yourusername \ AppData \ Local \ Xamarin）。 我通常删除这里的所有内容，以便重建它们。
遗憾的是我不得不做上面列出的所有事情，以使Resource.Designer.cs在以前的场合工作。
Delete everything inside your Resource.Designer.cs file (not the file itself) and rebuild. It should regenerate the file for you and the errors will disappear.
First next step
Make sure your Google support packages are all at 23.0.1.3. Thats a requirement for XF 2.0 but they should have been updated with the XF 2.0 upgrade.
When all else is failing (copied across from my answer to another question)
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 againYou might also want to add sobbing, praying or cursing in with those steps :)
One final thing, if that doesn't work, try the same again but this time uninstalling all NuGet packages and components instead of a reinstall. That has worked for me before.
Then make sure your cache's are clean (C:\Users\yourusername\AppData\Local\Xamarin). I normally delete everything in here so it can rebuild them.
I have unfortunately had to do everything listed above before to get the Resource.Designer.cs to work in previous occasions.

删除Resource.Designer.cs文件中的所有内容（不是文件本身）并重建。 它应该为您重新生成文件，错误将消失。
下一步
确保您的Google支持包全部为23.0.1.3。 这是XF 2.0的要求，但它们应该已经通过XF 2.0升级进行了更新。
当其他所有方法都失败时（从我对另一个问题的回答中复制）
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您可能还想添加抽泣，祈祷或诅咒这些步骤:)
最后一件事，如果不起作用，请再次尝试相同，但这次卸载所有NuGet包和组件而不是重新安装。 这之前对我有用。
然后确保您的缓存是干净的（C：\ Users \ yourusername \ AppData \ Local \ Xamarin）。 我通常删除这里的所有内容，以便重建它们。
遗憾的是我不得不做上面列出的所有事情，以使Resource.Designer.cs在以前的场合工作。
Delete everything inside your Resource.Designer.cs file (not the file itself) and rebuild. It should regenerate the file for you and the errors will disappear.
First next step
Make sure your Google support packages are all at 23.0.1.3. Thats a requirement for XF 2.0 but they should have been updated with the XF 2.0 upgrade.
When all else is failing (copied across from my answer to another question)
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 againYou might also want to add sobbing, praying or cursing in with those steps :)
One final thing, if that doesn't work, try the same again but this time uninstalling all NuGet packages and components instead of a reinstall. That has worked for me before.
Then make sure your cache's are clean (C:\Users\yourusername\AppData\Local\Xamarin). I normally delete everything in here so it can rebuild them.
I have unfortunately had to do everything listed above before to get the Resource.Designer.cs to work in previous occasions.
