我有一个在旧VS（2017）上运行的旧项目，目前正在尝试在vs2022中运行，所以我试图升级。我得到了多个与OxyPlot相关的错误。这里是错误。
第一个错误：

Severity    Code    Description Project File    Line    Suppression State
Error       Invalid value 'armeabi' in $(AndroidSupportedAbis). This ABI is no longer supported. Please update your project properties to remove the old value. If the properties page does not show an 'armeabi' checkbox, un-check and re-check one of the other ABIs and save the changes.   OxyPlot.Xamarin.Android

字符串
第二个错误：

Error       The $(TargetFrameworkVersion) for OxyPlot.Xamarin.Forms.Platform.Android (v9.0) is less than the minimum required $(TargetFrameworkVersion) for Xamarin.Forms (10.0). You need to increase the $(TargetFrameworkVersion) for OxyPlot.Xamarin.Forms.Platform.Android.    OxyPlot.Xamarin.Forms.Platform.Android

型
因此，我通过将.csproj从

`<AndroidSupportedAbis>armeabi</AndroidSupportedAbis>`

型
至

<AndroidSupportedAbis>x86_64</AndroidSupportedAbis>

型
问题似乎很好，但在I clean和rebuild之后出现了另一个错误，如下所示

Severity    Code    Description Project File    Line    Suppression State
Error       invalid file path '...\OxyPlot\OxyPlot.Xamarin.Android\obj\Debug\100\res\main.xml'. OxyPlot.Xamarin.Android

型
对于第二个错误。我换了project properties -> application -> compile using Adnroid version: (Target Framework) to Android 10.0。在clean和rebuild之后，错误成倍增加并疯狂增长，如下所示：

此外，我已经尝试clean project，然后删除bin和obj文件夹，关闭VS和重新打开和重建。仍然存在错误。
你知道吗？先谢谢你。
