我有一个应用程序已准备好发送给 Apple，以便他们审核。一切正常，除了当我将它发送到 App Store Connect 时，我收到一封电子邮件，说它太大了。
在做了一些研究之后我发现，几乎最后的手段就是改变链接器的行为。我将它设置为“不链接”，一切正常，除了文件太大，大约 68.4 MB。当我更改 Link Framework SDKs Only 时，应用程序运行，但我无法通过我的登录，因为尽管它连接到数据库但我收到错误。
这是我得到的错误:
The type initializer for 'Microsoft.EntityFrameworkCore.SqlServer.Query.ExpressionTranslators.Internal.SqlServerCompositeMethodCallTranslator' threw an exception.
这是内部异常:
Value cannot be null.
Parameter name: key

如何让我的应用正常工作？
编辑
我放入了 linkskip，但它似乎没有做任何事情，除非我做错了吗？
--linkskip=Microsoft.EntityFrameworkCore.SqlServer.Query.ExpressionTranslators.Internal.SqlServerCompositeMethodCallTranslator
最佳答案
感谢@Andrew 和@apineda 帮我解决了这个问题。
我最后只是在我的 mtouch 参数中添加了两件事
--linkskip=System.Core --linkskip=mscorlib
这没问题!
