c# - 无法在 Xamarin 表单的 Release模式下构建解决方案

Question

由于某种原因，我无法在 Release模式下构建项目，这是我遇到的错误

Error       The "XamlCTask" task failed unexpectedly.
System.InvalidOperationException: Operation is not valid due to the current state of the object.

尝试了一切，更新了 Xamarin.forms 包，删除了 bin/obj 文件夹，重新启动了管理员权限，任何输入都将受到深深的赞赏，因为我无法将应用程序投入生产

Not able to build a solution in Release mode in Xamarin forms

是的，这是 Xamarin.Forms 的一个已知问题，此问题的解决方法是将 Xamarin.Forms 降级到 2.3.4.224 .

您可以查看以下线程以获取更多详细信息:

Build failed when upgrade Xamarin.Forms to latest version

此外，如果您的 Xamarin.Form 版本与您安装的 NuGet 包不兼容/匹配，我们最好更新 nuget 包以匹配 NuGet 包的依赖项。

希望这有帮助。
