I get the following message in the eventlog for my service:
Exception: System.NullReferenceException
Message: Object reference not set to an instance of an object.

I use the log4net in more projects in the system beside the webservice and it just getting randomly stuck there too.
I looked in source file of log4net where the exception occurs and it happens when it tries to perform file rolling
if (m_rollSize)
{
/* this line*/ if ((File != null) && ((CountingQuietTextWriter)QuietWriter).Count >= m_maxFileSize)
{
RollOverSize();
}
}
what could be causing this? it just happens totally random
After a lot of searching i finally found the problem, the log4net actually hangs because it tries to print error to console, and my application is hidden so it fails to print to the console and just stops the thread that called the log4net.

I am trying to create a eventhandler for a msmq message router and I almost just copied a online example from msdn library
example 2.
But when I invoke messageQueue.BeginReceive() I get a IllegalFormatName exception.
I am using a private queue
Using VS 2015 on windows 10
Solution is using .Net 4.5.2
I got no problems sending messages to any of my private queues or reading from them if I use messageQueue.Receive()
Exception details below:

My c# program uses Matlab dll and it works find as long as I run it in Debug mode.
but as I trying to run it in Release mode it crashes immediately when creating it's instance.
It trows TypeInitializationException.
Thanks for your help

this is the key, and it means you are mixing platforms somwhow. A 32bit process cannot load 64bit dlls and vice-versa. If a process tries to do so anyway, it throws the above exception.
You say you only changed from Debug->Release, so it's likely something that has to do with platform changed as well. Compare settings for all projects in the Configuration Manager. They all should be x86 or x64 (not AnyCPU). Which one depends on your matlab dll's platform (set when building it).
So I've written my own game class, which is initialized like so (BTW, this is F# not C#):
static member RunGame() =
use engine = new Root()
// For now, always use OpenGL
engine.RenderSystem <- engine.RenderSystems.["OpenGL"]
use renderWindow = engine.Initialize(true)
let game = new Game(engine, renderWindow)
game.Load()
engine.FrameStarted.Add(game.HandleInput)
engine.FrameRenderingQueued.Add(game.OnRenderFrame)
engine.StartRendering() // The error is thrown somewhere inside here
game.Unload()
and this is simply how I try to shut the system down:
static member this.HandleInput(e: FrameEventArgs) =
input.Capture()
if input.IsKeyPressed(KeyCodes.Escape) then
root.Shutdown
root is the first argument in the constructor, so it is the same object as engine in the first sample. Here's the full error:

Am I doing something wrong or is this an Axiom bug?

Is this a problem specific to WintRT?
Is there a workaround?
According to the MSDN documentation for that error message, the fix for that error is to either "close some applications" or "increase the size of your paging file".
Given that, you might want to start by looking in Task Manager and see if your application is using a totally unreasonable amount of memory (or if some other process is). If your process has a memory leak, it might lead to this problem.
