A simple ToDo List application project for creating, reading, updating, and deleting ToDo events. The events have a task description and a details field. The events are assigned due dates.

This application uses the Prism Library for providing MVVM design pattern for the data domain, code logic, and the UI Interface; and to provide navigation between functional views in the application. The ToDo list data is stored in a local file in JSON format; storage is in the application's directory, in a subfolder named Data.

• Prism 6 Library
• Entity Framework
• NuGet Package installation

The Solution and Projects were built in Microsoft Visual Studio 2015 Community Edition. Please Rebuild the solution in Visual Studio to fetch the NuGet Packages and restore the References used in the projects.

The TODO app was built with the following goals in mind:

Create an application that provides the ubiquitous "TODO list" example application, with the basic functionality given below:

• As a user, I can add a TODO to the list.
• As a user, I can see all the TODOs on the list in an overview.
• As a user, I can drill into a TODO to see more information about the TODO.
• As a user, I can delete a TODO.
• As a user, I can mark a TODO as completed.
• As a user, when I see all the TODOs in the overview, if today's date is past the TODO's deadline, highlight it.

• a task (just a simple sentence or two is fine)
• a deadline date
• a completed flag (stored as a Date), and
• an optional "more details" field that allows for more details to be given (a single large text area is fine for this).
• the date that it was created is also stored

The list of TODOs is kept in memory, and stored in a text file.

• This is a "native GUI" application.
• The Project is using
  • the C# language
  • WPF for the UI
  • an MVVM design pattern
    • [Model ~ View ~ View-Model]
• .NET libraries and external libraries are pulled in as part of a build process with NuGet.

• Overdue items are highlighted in RED.

• Items due today are highlighted in ORANGE.

• Completed items are highlighted in GRAY.

• There is a search box in the upper left corner of the screen. It can be used to search and filter out task descriptions.

• The columns of the to do list can be sorted in ascending or descending order also, by clicking on the column headers.

• The action buttons in the selected row of the list brighten up. Select the respective button to view more details, flag the task as complete, or delete the task.

• There is a button in the upper right hand corner to add new tasks to the ToDo task list.
