A Library for implement the factory method for Dependency injection in asp.net core.
Add following nuget package in your asp.net core Solution.
PM> Install-Package Framework.AspnetCore.Factory -Version 1.0.0
> dotnet add package Framework.AspnetCore.Factory --version 1.0.0
<PackageReference Include="Framework.AspnetCore.Factory" Version="1.0.0" />
Create a Services classes.
using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.Linq;
using System.Threading.Tasks;
namespace Api.Demo.Contexts
{
public interface IDemo1
{
String TestDemo();
}
public class Demo1 : IDemo1
{
String IDemo1.TestDemo()
{
Debug.WriteLine("Demo 1");
return "Demo 1";
}
public int Test { get; set; }
}
}
using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.Linq;
using System.Threading.Tasks;
namespace Api.Demo.Contexts
{
public interface IDemo2
{
String TestDemo();
}
public class Demo2 : IDemo2
{
String IDemo2.TestDemo()
{
Debug.WriteLine("Demo 2");
return "Demo 2";
}
}
}Go to Startup.cs file, In the ConfigureService method add the following services.
services.AddFactory((x) =>
{
x.AddTransient<IDemo1, Demo1>();
x.AddSingleton<IDemo2, Demo2>();
// Or using fluent
//x.AddTransient<IDemo1, Demo1>()
// .AddSingleton<IDemo2, Demo2>();
});Full ConfigureService Method Code.
public void ConfigureServices(IServiceCollection services)
{
services.AddControllers();
services.AddFactory((x) =>
{
x.AddTransient<IDemo1, Demo1>();
x.AddSingleton<IDemo2, Demo2>();
// Or using fluent
//x.AddTransient<IDemo1, Demo1>()
// .AddSingleton<IDemo2, Demo2>();
});
services.AddSwaggerGen(c =>
{
c.SwaggerDoc("v1", new OpenApiInfo { Title = "Api.Demo", Version = "v1" });
});
}Inject factory in the controller class.
