我正在阅读 EF 的源代码,并在下面找到了这个方法。根据方法名,确定dbcontext被加载。当我使用 EF Codefirst 示例对此进行测试时,此方法将当前程序集(我的示例控制台)添加到“_knownAssemblies”中。
我没有看到任何加载程序集的代码。而且我没有看到任何检查程序集是否已加载的代码。
这是命名问题还是我错过了什么?提前致谢。

DebugCheck.NotNull(contextType);

|| _knownAssemblies.ContainsKey(contextAssembly))

return;
}

lock (_lock)

if (_configurationOverrides.Value.Count != 0)

return;

_loader.TryLoadFromConfig(AppConfig.DefaultInstance) ??
_finder.TryFindConfigurationType(contextType);
