This is an add-in for Fody

Injects some very basic method timing code.

Introduction to Fody

The nuget package

https://nuget.org/packages/MethodTimer.Fody/

PM> Install-Package MethodTimer.Fody

Your Code

public class MyClass
{
	[Time]
	public void MyMethod()
	{
		//Some code u are curious how long it takes
		Console.WriteLine("Hello");
	}
}

What gets compiled without an Interceptor

public class MyClass
{
    public void MyMethod()
    {
        var stopwatch = Stopwatch.StartNew();
        try
        {
            //Some code u are curious how long it takes
            Console.WriteLine("Hello");
        }
        finally
        {
            stopwatch.Stop();
            Debug.WriteLine("MyClass.MyMethod " + stopwatch.ElapsedMilliseconds + "ms");
        }
    }
}

What gets compiled with an Interceptor

If you want to handle the logging you can define a static class to intercept the logging.

The interceptor takes the following form.

public static class MethodTimeLogger
{
    public static void Log(MethodBase methodBase, long milliseconds)
    {
        //Do some logging here
    }
}

Then this will be compiled

public class MyClass
{
    public void MyMethod()
    {
        var stopwatch = Stopwatch.StartNew();
        try
        {
            //Some code u are curious how long it takes
            Console.WriteLine("Hello");
        }
        finally
        {
            stopwatch.Stop();
            MethodTimeLogger.Log(methodof(MyClass.MyMethod), stopwatch.ElapsedMilliseconds);
        }
    }
}

Whats in the nuget

In addition to the actual weaving assembly the nuget package will also add a file TimeAttribute.cs to the target project.

[AttributeUsage(AttributeTargets.Assembly | AttributeTargets.Module | AttributeTargets.Class | AttributeTargets.Method | AttributeTargets.Constructor,AllowMultiple = false)]
internal class TimeAttribute : Attribute
{
}

At compile time this attribute and all usages to it will be removed from the target assembly. If you want to re-use the class in a common assembly change the class from internal to public. This will result in the class not being removed at compile time.
