这是一个叫做AutoMapper的插件，主要功能是让两个类的内容进行映射，最常见的例子就是EF查询出的内容映射到一个实体类上去然后返回这个实体类例如：
Mapper.CreateMap<查询出的类, 要映射并且返回的类>();
如果这时出现
Missing map from Nullable`1 to String. Create using Mapper.CreateMap
Mapper.CreateMap<查询出的类, 要映射并且返回的类>();
如果这时出现
Missing map from Nullable`1 to String. Create using Mapper.CreateMap
