被Xamarin链接"是什么意思?

What does "linked out by Xamarin" mean?

推荐答案

Xamarin.iOS链接器从已编译的应用程序中删除未使用的代码.他们检查编译后的代码，并删除所有看起来好像在应用程序运行期间将被引用的代码.

The Xamarin.Android linker and Xamarin.iOS linker remove unused code from a compiled application. They inspect the compiled code and remove any code that doesn't appear as if it would be referenced during a run of the application.

由于此分析是在已编译的二进制文件上进行的(例如，静态分析)，因此在某些情况下，应用程序确实使用某些代码，但链接程序无法检测到这种用法.因此，链接器将删除此代码，即使使用该代码也是如此.当应用程序实际运行时，这会导致问题.

Because this analysis is done on a compiled binary (e.g., a static analysis), there may be some cases where an application does use some code but the linker can't detect such a usage. Thus, the linker will remove this code, even though it is used. This will lead to problems when the application actually runs.

引用的Akavache.doc文件暗示Akavache.Sqlite3是其中一种情况，其中Xamarin链接器将无法告知其正在被使用，因此链接器将错误地将其删除.文档建议您添加引用，以防止Xamarin链接程序删除Akavache.Sqlite3-即，防止Xamarin将链接库链接"到您的应用程序.

The quoted Akavache docs imply that Akavache.Sqlite3 is one of these cases, where the Xamarin linker will not be able to tell that it is being used, and thus the linker will remove it incorrectly. The docs recommend you add a reference to prevent the Xamarin linker from removing Akavache.Sqlite3 - i.e., to prevent the library from being "linked out" of your application by Xamarin.
