             Dev tunnels allow you to securely expose local web services to the internet, creating a public URL that tunnels traffic directly to your development machine. This is useful for testing, collaboration, and integration with external services Uses of dev tunnel in daily development Debugging and testing on different devices Dev tunnels eliminate the need for complex network configurations when you need to test your application on a separate device. You can access your local server from a mobile phone, tablet, or another computer by simply navigating to the tunnel's public URL.  Integrating with external services and webhook  Many third-party services, like payment gateways, social media APIs, and communication platforms (e.g., Twilio), rely on webhooks to send real-time notifications to your application.  Since webhooks cannot send requests to localhost, you need a public URL to receive them.   A dev tunnel provides a secu...

Run cs file without main method using .NET 10 You don't have to explicitly include a main method in a console application project. Instead, you can use the  top-level statements  feature to minimize the code you have to write. Top-level statements allow you to write executable code directly at the root of a file, eliminating the need for wrapping your code in a class or method. This means you can create programs without the ceremony of a Programm  class and a Main method. In this case, the compiler generates a Program  class with an entry point method for the application. The name of the generated method isn't Main  it's an implementation detail that your code can't reference directly. 1. create ".cs" file, lets create "app.cs" 2. Open folder path in any terminal 3. Run the file using command "dotnet run aap.cs" Note : Prerequisite .NET 10  Example statements 1. Console.WriteLine("Hello World!");  output : Hello World! 2.  int a...
