How can an external library be integrated into a project created in Visual Studio?

In Visual Studio, to integrate an external library into a project, NuGet — a package manager for .NET — is usually used. The process includes the following steps:

1. Open the project in Visual Studio.
2. Go to the "Project" menu → "Manage NuGet Packages".
3. Search for the required library.
4. Select the desired version and install the package.

After installation, the library is automatically added to the project's dependencies, and it can be used in the code via the using directive.

If the library is not available through NuGet, you can add it manually:

• Copy the DLL to the project folder.
• In the Solution Explorer, select "Add" → "Reference" → "Browse" and specify the path to the DLL.

This will allow you to use the functionality of the external library in your project.
