I need a C# dot net developer to implement REST API project coding

The original source package is attached below (it's called [login to view URL]). Pull that and make sure you can build. There are some notes in the README. Add support (state management, semantics, etc.) for: • Remove (DELETE) a draft or cancelled timecard • Replace (POST) a complete line item • Update (PATCH) a line item • Verify that timecard resource is consistent with the calling actor (you need to know the caller) • Verify that timecard approver is not timecard resource (you need to know the caller) • To do the above two operations will require that you implement an Employee API that can accept GET for single and collection employees, and can accept a POST to register an employee • Add support to root document for creating a timesheet • Complete support in root document for employee list and registration Upload the results of your program running and a `diff` between the original package and your source code. Note: The code can be implemented in visual studio tool and the deliverable is Upload the results of your program running in a word or pdf document of code snippets running a `diff` between the original package and your updated source code.
