Xamarin窗体部署错误无法加载程序集“System.Memory”

Question

Xamarin形成Android

最近的nuget包级别导致了这个错误。我们只使用稳定的包，但我开始尝试最近的Xamarin预发布包，看看问题是否已经解决。

生成和调试部分的输出有错误。

装载机探测位置：“System.Memory”。 07-06 10: 10:10:51.972 F/单机器人程序集( 4029)：无法在启动注册期间加载程序集“System.Memory”。

编译设置为使用最新版本(8.1)，最低版本为7.0

在其他帖子中，我尝试删除共享运行时，并尝试使用已使用的共享运行时检查Android选项。

Can you try this Go to android Project>Right the Properties>Go to Android options>Advanced>In supported architecture tick all and set Java max Heap Size to 1 G if that not working can you try this 


This seemed to work for me. I will have to do more testing when I get time. Found it on the EF Core git bug lists.

Manually edit your csproj file and define, that the NU1605 warning shouldn't be treated as an error.

<PropertyGroup>
  <NoWarn>$(NoWarn);NU1605</NoWarn>
</PropertyGroup>
Now in your Project File add the Package:

<PackageReference Include="System.Runtime.CompilerServices.Unsafe" Version="4.3.0" />
Then I would:

Clean the NuGet Caches
Clean all bin and obj folders
Restore the Packages
Build
