Setting Up Environment Variables (If Needed)

In most cases, the installer automatically sets up the necessary environment variables. However, if you encounter issues or need to configure them manually, here’s how:

1. Search for "Environment Variables" in the Windows search bar and click "Edit the system environment variables."
2. Click the "Environment Variables..." button.
3. In the "System variables" section, look for a variable named "Path" and select it.
4. Click "Edit..."
5. Add the path to the .NET Core SDK to the list. The default path is usually C:\Program Files\dotnet\.
6. Click "OK" to save the changes.

Setting up environment variables manually is typically only necessary if the installer fails to configure them automatically or if you have custom installation requirements. The "Path" environment variable is crucial because it tells the operating system where to find the .NET Core runtime and tools. By adding the path to the .NET Core SDK to this variable, you ensure that you can run .NET Core commands from any location in the command prompt or PowerShell. If you encounter issues with the .NET Core commands not being recognized, double-check that the "Path" variable is correctly configured. You may need to restart your computer for the changes to take effect. Also, make sure that you have the correct path to the .NET Core SDK.
