 # AutoMapper.EF6
 Extensions for AutoMapper and EF6
+
+This contains some useful extensions I've used with AutoMapper and EF6. Instead of this:
+
+```
+Mapper.CreateMap<Employee, EmployeeDto>()
+  .ForMember(d => d.FullName, opt => opt.MapFrom(src => src.FirstName + " " + src.LastName));
+
+var employees = await db.Employees.ProjectTo<EmployeeDto>().ToListAsync();
+```
+
+You can do this instead:
+
+```
+public class Employee {
+  [Computed]
+  public string FullName { get { return FirstName + " " + LastName; } }
+}
+Mapper.CreateMap<Employee, EmployeeDto>();
+
+var employees = await db.Employees.ProjectToListAsync<EmployeeDto>();
+```
+
+This package wraps up calling `ProjectTo`, the DelegateDecompiler Decompile/DecompileAsync methods, and then the LINQ methods to execute the queryable (ToList, ToArray, Single, SingleOrDefault etc).
