0After while loop, write following

return employeees;

As the error suggest, you are not returning anything from the get so you have to return the IEnumerable<Employee> collection.

Hope this works.

Thanks

Hi,
Whenever we write any getter properties,then it must be returned,in your case you need to return employees object at the end of the code as
return employees.
