Here is the OnChange that is supposed to run when FileWatcher detects a new file in the temp directory:

<div>
where is your FileSystemEventHandler?
</div>

<div>
Have you looked in the online help about the FileWatcher class 
<a href="https://msdn.microsoft.com/en-us/library/system.io.filesystemwatcher(v=vs.110).aspx?cs-save-lang=1&cs-lang=csharp#code-snippet-2" rel="ugc">https://msdn.microsoft.com/en-us/library/system.io.filesystemwatcher(v=vs.110).aspx?cs-save-lang=1&cs-lang=csharp#code-snippet-2</a> 
There is an example there of how to use it
</div>

<div>
Line 39 in my first code post is where I set the FileSystemEventHandler to fire the Onchanged in my 2nd code snippet. &nbsp; 
 
Yes, I did review the MSDN information but I it doesn't explain how to setup the FileSystemWatcher as a service. &nbsp;Like I explained in my original post, my service starts and the Created event does fire my code once when it detects the first file saved to the temp directory. &nbsp;However, any subsequent file, nothing happens. &nbsp;It doesn't seem to be catching any errors either. &nbsp; 
 
Thanks for everyone's comments thus far.

<div>
instead of doing all that process in you OnChanged event handler, have you tried just to call something really simple like your LogEvent? Your file might not be ready to be processed when that event is triggered. 
 
Also, have a look at <a href="http://emoreau.com/Entries/Articles/2005/04/The-FileSystemWatcher-component.aspx" rel="ugc">http://emoreau.com/Entries/Articles/2005/04/The-FileSystemWatcher-component.aspx</a>

Great solution! &nbsp;I spent a couple hours looking at this and couldn't figure it out. &nbsp;I am now writing exceptions to a log file and that seems to have done the trick.

C# Service FileSystemwatcher isse

C# is an object-oriented programming language created in conjunction with Microsoft’s .NET framework. Compilation is usually done into the Microsoft Intermediate Language (MSIL), which is then JIT-compiled to native code (and cached) during execution in the Common Language Runtime (CLR).

The .NET Framework is not specific to any one programming language; rather, it includes a library of functions that allows developers to rapidly build applications. Several supported languages include C#, VB.NET, C++ or ASP.NET.
