SimpleAop

SimpleAop is library for your Aop or Dynamic Proxy programming. I converted it more simply from the old framework.

Here includes following libraries.

• SimpleAop
  It needs Aop or Dynamic Proxy programming.

• SimpleAop.Extensions.DependencyInjection
  Here includes IServiceCollection extension class for .NET Core or ASP.NET Core.

To install, run following command or Nuget browser of visual studio.

Functionally list.

• Dynamic Proxy
• Aop of methods and classes.
• General methods.
• yield return
• async/await
• Generate constructors.

dotnet add package SimpleAop

dotnet add package SimpleAop.Extensions.DependencyInjection

Dynamic Proxy Programming

It's simple. We just need Interface declaring and Implementation class.

public interface IPrint
{
    void PrintMessage(string message);
}

public class Print : IPrint
{
    public void PrintMessage(string message)
    {
        Console.WriteLine(message);
    }
}

And to use it,

var type = DynamicProxyFactory.Create<IPrint, Print>();
var obj = (IPrint) Activator.CreateInstance(type);

obj.PrintMessage("Hello World");

The type generate random character from the Guid. It's just first SimpleAop version.

Aop Programming

Additionally, provider OnMethodBoundAspect attribute class. We just inherites it.

public class LoggingAspectAttribute : OnMethodBoundAspectAttribute
{
    public override void OnBefore(IAspectInvocation invocation)
    {
        Console.WriteLine($"--- Before: {invocation.Method}, {invocation.Object}, {string.Join(",", invocation.Parameters)} ---");
    }

    public override void OnAfter(IAspectInvocation invocation)
    {
        Console.WriteLine("--- After ---");
    }
}

And add logging attribute,

[LoggingAspect]
public class Print : IPrint
{
    public void PrintMessage(string message)
    {
        Console.WriteLine(message);
    }
}

So result is,

--- Before: Void PrintMessage(System.String), 9a19fdd7e64943c9b22ae2c79a886b50, Hello World ---
Hello World
--- After ---

ASP.NET Core or .NET Core

Provide some methods is,

• AddWithProxy
• AddTransientWithProxy
• AddScopedWithProxy
• AddSingletonWithProxy

In Startup.cs file,

services.AddSingletonWithProxy<ITestService, TestService>();

I did make SimpleAop.Sample.AspNetCoreWeb project.

Let's run it, and watch the console log.
