Hi,
I just tried to convert my current project to the new beta 2 of the .net
framework and I encountered some problems with my thread synchronization -
that formerly worked well.
When I release a monitor by System.Threading.Monitor(myvar) I receive the
following error message:
System.Threading.SynchronizationLockException: Object synchronization method

I have to ask a stupid question regarding Monitor.
Wait() and Pulse() make be used to wait for and signal events in a
given thread.
However, neither can be used until calling within a synchronized block
between calls to Enter() and Exit().
Am I missing something when I say that it seems useless to use this
facility to synchronize threading activities between 2 or more

Hi,
I have been looking into the claim that the keyword lock is not safe
when exceptions are possible. That lead me to try the following code,
which I think has uncovered a serious error in the .NET 2.0 framework.
Note that this runs better, but not perfectly, on .NET 1.1.
Note: The numbers are line numbers needed to match the callstack of the
exception below.

I am having some strange thread synchronization problems that require me to
better understand the intricacies of Monitor.Wait/Pulse.
I have 3 threads. Thread 1 does a Monitor.Wait in a SyncLock block
protecting a resource. Thread 2 and 3 also have a SyncLock block protecting
the same resource and after executing some code in their blocks they both do
a Monitor.Pulse to hand of the locked resource back to thread 1.
While thread 1 has...

Background:
Upon receiving a Monitor.Pulse, the waiting thread is moved to the ready
queue. When the thread that invoked Monitor.Pulse releases the lock, the
next thread in the ready queue (which is not necessarily the thread that was
pulsed) acquires the lock.
How can I ensure that the waiting thread gets priority in acquiring the lock
over others in the waiting queue?
I need the waiting thread to be the one next in line to acquire the...

Most computers default to English, but sometimes we require a different language, especially when relocating. Forgot to request a specific language before your computer shipped? No problem! You can effortlessly switch the default language on Windows 10 without reinstalling. I'll walk you through it.
First, let's disable language synchronization. With a Microsoft account, language settings sync across devices. To prevent any complications,...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

I'm particularly interested in Zigbee because I've heard it does some...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...
