Create userinterface (C#) to feed exiting API.

Our company is using a project management tool, which has a good API. Employees need to track/administer/specify the number the hours they worked on a certain project /task. To simplify the process of resistering the hours, we want to build a simple dotnet/C# application that is installed locally. The employee can enter things like number hours and a description (etc). Upon submit, all information provided will be inserted in the project management tool using the exiting API. You are asked to build the small dotnet C# applicatintion.
