A real-time command-line weather application built in C# that fetches and displays current weather data for any city worldwide using the OpenWeatherMap API.

• Real-time Data: Fetches the latest temperature, weather conditions, humidity, and wind speed.
• City Search: Allows users to search for weather by city name.
• Metric Units: Displays temperature in Celsius (°C) and wind speed in meters per second (m/s).
• User-Friendly Interface: Provides clear console output with weather emojis for easy reading.
• Error Handling: Gracefully handles invalid city names or API connection issues.

• Language: C#
• Framework: .NET 9.0 (Console Application)
• Dependencies: System.Net.Http for API calls and System.Text.Json for JSON parsing.
• External API: OpenWeatherMap API

To run this application, you must have the following installed:

• .NET 9.0 SDK or later.
• A code editor like Visual Studio 2022 or Visual Studio Code.

1. Clone the Repository:

   git clone [https://github.com/YOUR-USERNAME/Weather-app-using-csharp.git](https://github.com/YOUR-USERNAME/Weather-app-using-csharp.git) cd Weather-app-using-csharp

2. API Key Configuration (Crucial Step)

   The application currently uses an API key embedded in the Program.cs file:

   string apiKey = "5c05e502387370283e249b6857d8b621"; // THIS IS THE KEY USED IN THE UPLOADED CODE

   ** Security Warning:** Embedding the API key directly in the source code is not a secure practice for public repositories. For better security and to ensure the app works for others, please create your own free API key from OpenWeatherMap and replace the value in Program.cs with your personal key.

3. Run the Application: Navigate to the project directory containing the .csproj file and execute:

   dotnet run

1. The welcome message will display, prompting you for a city name.
2. Type the name of any city (e.g., London, Dhaka, Tokyo).
3. The application will display the current weather details.
4. You will be prompted to check another city or type exit to close the application.
