practice code for asp.net framework (not core)

ASP.NET Framework Practice

Environment

• Windows 10
• Visual studio 2019 Community
• ASP.NET Framework 4.7.2

Setting

• Project Build : ASP.NET Web Application(.NET framework)
• Controller Build : Web Api2 (Empty Scaffolder)

Used thrid-party lib

• Newtonsoft.Json (v12.0.2) - json
• Unity (v5.11.10) - DI framework
• xunit (v2.4.1) - unit test framework
• log4net (v2.0.12) - logging

Unit testing

1. Install Extension

   • Explorer xunit.net.TestGenerator
   • Restart visual studio
   • You can generate test code. (right click on target class.)

2. Example

using DemoWebApi.Models;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading;
using System.Threading.Tasks;
using Xunit;
using Xunit.Abstractions;
