develop dotnet core mvc application to measure distance

Task: Create a DotNet Core console application (or MVC application) to calculate distances between source and destination. I would like to use Google APIs to do these calculations, as well as SQL Server to do the same. In [login to view URL] you create an option to indicate whether to use Google or SQL Server method to perform the calculations. Functionalities: 1 - Geocode: transform a pair of coordinates into a full address, inclusing streetname, number, postalcode, neighborhood, city, state, country     The coordinates must be stored in SQL Server / DotNet Core Geography datatype (tipo 4326) 2 - Geodecode: transform an address into a pair of coordinates     The coordinates must be stored in SQL Server / DotNet Core Geography datatype (tipo 4326) 3 - Calculate distances using these methods:     a) Between 2 addresses     b) Between 2 geographic coordinates        Provide an implementation using SQL Server (I provide some source code below) and one with Google APIs c) Between an address and 1 geographic coordinate d) Between a geographic coordinate and 1 address 4 - Show the source and destination coordinates / addresses on the map, with a symbol which indicates the start and end positions     and a straight line between these coordinates Deliverables: Visual Studio 2017 Solution with 1 DotNet Core 2.1 project which implements the requirements. Budget: USD 40 max.
