Regretfully, I have a small issue with starting the Web App client, but it does build. Just when it runs, nearly all calls to the Web API result in a 404. I also have not done addresses and contacts in the client, nor the export. I hope you can evaluate my skills just from the code provided.
The solution was developed in Visual Studio and ASP.NET Core 2.0 using SQL Server 2017.
However I have scripted the database for MSSQL 2014. A script for creating the database
with data is present in the Data folder of the repo.
The solution comprises a web application for managing Client information.
This uses a DataClient to make calls to a Web API via HttpClient.
The API supplies CRUD services for The Client project.
The API controllers delegate their responsibility to a DataServer for data access
and very little progress.
