The Executing assembly in production is normally in a folder that "hangs off" "Program Files" or "Program Files (x86)", and folders in that path are normally write protected for antivirus reasons. Use a "publically writable" folder like one below

string folderBase = Environment.GetFolderPath(EnvironmeAgreed. I just threw that in there for illustrative purposes

So I'm looking at NLog and Log4net. Why in the world does logging need to be so blasted complicated??? Now I'm sure some of you would say "Log4Net or NLog isn't complicated", but at the most basicl level, what's wrong with this:
public class Logger
{
public static string LogFile { get; set; }static Logger() { if (string.IsNullOrEmpty(LogFile)) { var path = System.Reflection.Assembly.GetEntryAssembly().Location; LogFile = string.Format("{0}\\\\MyLogFile.txt", path); } } public static void Info(string message) { using (var sr = new StreamWriter(LogFile, true)) { sr.WriteLine(message); } }}
I've never understood why [This Much](https://csharp.today/log4net-tutorial-great-library-for-logging/) is needed just to write to a silly log file. Seems to me that these "tools" are just a solution looking for a problem. IMHO, WAY WAY WAY over-engineered.

Above was mentioned thread safe, another gotya is running multiple instances of the same prog. BTW:

If the log file is silly, why log anything.

For a simple application, what you posted may suffice. For complex, multi threaded services, the logging needs to be thread-safe, needs to be performant (even async), and may need to support multiple log listeners - and the target may be a text file, a database, azure storage, a web API, etc. That said, some of these logging frameworks kept adding features and now are unnecessarily complex, and may have reached a saturation point of over-engineering.

Adobe is doing the same thing with Photoshop now. I hope it doesn't get worse, that's been one of my favorite apps for so many years. If it goes to crap it'll be a sad, sad day for computerland. :((

I don't have it yet but the personal use subscription is quite affordable. 10 bucks a month gives you Photoshop and a couple other tools I think. You never really own it though - just a lease.

Yeah totally, and they allow you to use it on more than one computer, so it's not too shabby. But when you start using the new version (CC 2017) it just starts to seem like the new crap is just too much and is distracting. And I've always used Photoshop as an example of a simple, clean yet powerful UI design. Not so much now.

I disagree. When you have code running in production it;s usually more difficult to diagnose what's happening, so logging gives you an advantage.

Me thinks you misunderstood. By "the framework" he's referencing "the Logging framework", not logging in general.

We currently use log4net... To log to a file. Well, 10 files actually. Of 10 MB max. After which it overwrites the first again. That shit is totally unreadable and for some reason we have to log EVERYTHING. Yes, I DO believe some function was entered AND exited unless an error occurred, WHY THE HELL DO WE NEED TO LOG THAT!? The worst part, our source code is littered with debug log statements and on all environments we have the minimum log level set to info, so the debug logs never even show. Some people say "it's easy for debugging", but since when is a log file easier for debugging than a friggin' debugger!? Then again, I recently figured out a bug in three minutes using nothing but an error message and a stack trace after a coworker angrily gave me the (my) code because "I didn't add log statements and now he had to spent 30 minutes figuring out what went wrong!" It was a NullReference and by just looking at the code you could tell what parameters could be null, well at least I could :~ Yes, logging is good, but only if they are exception logs (with stack trace!!!) or logging that is required for the business. And rarely for debugging purposes, for example when multi-threading or handling input events (but in your console while debugging, not in a log file on production). Funny enough I've had this discussion with multiple people who all disagree with me (and despite all that logging which I don't use I usually find bugs faster) :confused:

Well, I agree that config is a bit of pain to sort out. But like with WCF you do it once then forget about it.

Quite a lot. Opening and closing a file every time you want to write a line isn't going to perform well. It *may* not be threadsafe, there's no mention of when the line was written or from which thread it happened. It always writes to a file, good for services but rubbish for a console app and if you've done it right your app will be both (enterprise solutions). It doesn't standardise on the format of each log line (important if you use a decent viewer). There's no concept of level - how do you distinguish a bit of helpful text from a critical error? How do you stop your file growing to GBs? Each to their own...

I wrote my own logger for that reason (and because it is fun to write stuff). If it is useful for you, you can check it out here: GitHub - sizingservers/sizingservers.log: An application logger for any 64 bit .Net 4.5 (and up) Windows desktop (maybe other app types) app.[^] Cheers

Personally, I've never needed to debug live systems. Well, once... Because my logger failed! Really, the software worked as expected, except for the logging :~ All the other times an exception log sufficed to fix the problem :)
