The best way of accomplishing this is using a named mutex. Create the mutex using code such as: bool firstInstance; Mutex mutex = new Mutex(false, “Local\\” + someUniqueName, out firstInstance); // If firstInstance is now true, we’re the first instance of the application; // otherwise another instance is running.

What is single instance application?
A Single Instance application is an application that limits the program to run only one instance at a time. This means that you cannot open the same program twice.
What is an instance of a program running on a computer?
An instance is a single copy of the software running on a single physical or virtual server. If you run two copies of the software on the same physical or virtual server, that counts as two instances.

How do I block multiple instances of a program in Windows 10?
In order to disable multiple instances of an app on Windows 10, you need to install a free app called SingleInstance. Go ahead and download, and run the app. The app, by default, has one app pre-configured and that’s the Calculator app on Windows 10.
How do I restrict a class to create one instance in C#?
One option is to just declare a static class with only static members. Or you can implement the Singleton pattern by giving the class a private constructor: public class MySingleton { public static readonly MySingleton Instance = new MySingleton(); private MySingleton() { } // Members … }
What is multi instance?
Multi-instance queue managers are instances of the same queue manager configured on different servers. One instance of the queue manager is defined as the active instance and another instance is defined as the standby instance.
What is an ERP instance?
An ERP instance is simply an installation of an ERP application. Therefore, a single-instance ERP solution is one that uses the ERP system for all your business operations—on either the front end or the back end.
What is difference between instance and server?
A server is a (physical or virtual) machine hosting SQL Server software. An instance is a collection of SQL Server databases run by a single SQL Server service, ahem, instance. You can view each separate instance you’re running in your service console. Each instance can be started or stopped individually.
What does separate instance mean?
In a multi-instance cloud, entirely separate instances (that is, separate copies of defined data items) are run parallel to one another.

What is a single instance database?
A single instance database consists of the following key components: DBMS software — A software program, such as IBM DB2, Oracle DBMS, Microsoft SQL Server, or Sybase Adaptive Server Enterprise (ASE), that is used to store and process data.

Why are there multiple instances of apps running?
Sometimes processes are split in order to save resources. For example for Google Chrome, multiple processes are launched, where each one is for browser, each extension, each tab. if you click “>” that should explain a bit more.
Why does Task Manager show multiple of the same app?
This usually happens if we initiate a program, the app takes longer than usual to start, and we double-click the icon again to start the program. If this is the first time you’re seeing this, you can right-click each instance in the Task Manager individually, and click End Task.
Why does Task Manager show multiple processes?
Google chrome uses multi-process architecture to prioritize performance while using the browser. This is the reason why the task manager shows multiple google chrome processes.
How do I restrict the number of instances of a class in C#?
Keep a static variable with the number of instances created. Increment that number with each construction of the object. Make the object IDisposable and decrement that number on each call to Dispose(). If you want it to be thread-safe, use Interlocked.
What is a Singleton in C#?
One of the commonly used design patterns in C# is the singleton pattern. This design pattern uses a single instance of a class to enable global access to the class members. Instead of having several instances of the same class, singletons have just one instance, and provide convenient access to that single instance.
How do I create a multi-instance queue manager?
Create the shares for the data and log files. Create the queue manager on one server. Run the command dspmqinf on the first server to collect the queue manager configuration data and copy it into the clipboard. Run the command addmqinf with the copied data to create the queue manager configuration on the second server.
How does multiple instance learning work?
Multiple Instance Learning (MIL) is a form of weakly supervised learning where training instances are arranged in sets, called bags, and a label is provided for the entire bag, opposedly to the instances themselves.
