Can I use spring AOP to log start and end of a method to help easy debuging

it helps some times You need to use @Around advice. Sample code should look like something below
code :
@Aspect
public class MethodLogging {

@Around(execution("@annotation(LogMessage)"))
public Object logStartAndEnd(ProceddingJoinPoint pjp){
    String name = pjp.getSignature().getName();
    logger.info("started " + name);
    Object obj = pjp.proceed();
    logger.info("finished " + name); 
    return obj;
}

}

Application start debuging at pool drain instruction

Application start debuging at pool drain instruction

I wish did fix the issue. I am build an iPhone application who try to perform a login via a Rest web service (WCF). The part who call the service work correctly. I receive data from the called service without any problem. But I have to parse the message using the NSXMLParser. When I introduce it in my application (this is the first time I used it) the application parse the message correctly but at the end of the application execution it's lunch gdb and pause the application at the start of [pool drain] instruction. , This can be done using method swizzling:
code :
#import <Foundation/Foundation.h>
#import <objc/runtime.h>

@interface NSAutoreleasePool(customDrain)

-(void) myDrain;

@end

@implementation NSAutoreleasePool(customDrain)

-(void) myDrain
{
    if ([self respondsToSelector:@selector(myDrain)])
    {
        NSLog(@"Draining...");

        // note that @selector(myDrain) was remapped 
        // to @selector(drain) during the process of 
        // the swizzling, so now, myDrain calls drain,
        // and drain calls myDrain.
        [self myDrain];
    }
    else 
    {
        NSLog(@"Remapping Failed!");
    }
}

@end

void SwizzleMethod(Class c, SEL orig, SEL new);
void SwizzleMethod(Class c, SEL orig, SEL new) {

    Method origMethod = class_getInstanceMethod(c, orig);
    Method newMethod = class_getInstanceMethod(c, new);

    if (origMethod && newMethod)
        method_exchangeImplementations(origMethod, newMethod);

}

int main (int argc, const char * argv[])
{
    NSAutoreleasePool *pool = [NSAutoreleasePool new];

    SwizzleMethod([NSAutoreleasePool class], @selector(drain), @selector(myDrain));

    [pool drain];
    return 0;
}

it should still fix some issue This sounds like a typical issue for AOP (Aspect Oriented Programming). PostSharp is a good and simple framework to do the job. Have a look at this post.
Another way would be you use reflection to get all the information you need. Then you would have one method which can handle whatever you give to it and extract all the information it can find.

hope this fix your issue Your code is all wrong. I suggest you lookup into the basics of C first. Anyway, this is how it's supposed to be done:
code :
int number;
printf("Pick a number\n");
scanf("%d", &number);
printf("you enterd the number: %d", number);
return 0;

I wish did fix the issue. I think you're mis-understanding how debugging works here. Visual studio is doing exactly what it's supposed to. It's stopping all execution on your breakpoint until you release it. In a real production environment, or while debugging without a breakpoint, you will see that it will return to both at the same time (as far as you could tell unless you're some extremely long running operation, in which case you should be using async/await).
In reality it (IIS) will queue the requests and process them .
