In C# generally the Garbage Collector is used, which automatically frees unused memory. However, in some cases, it is important to manage memory freeing manually:

• When an object uses unmanaged resources (files, network connections, descriptors) that are not controlled by the garbage collector.
• To free resources in a timely manner and prevent leaks and deadlocks.

For this, the IDisposable interface and the Dispose() method are implemented, where resources are explicitly released.

Example:

class FileHandler : IDisposable
{
    private FileStream _fileStream;

    public FileHandler(string path) {
        _fileStream = new FileStream(path, FileMode.Open);
    }

    public void Dispose() {
        _fileStream?.Dispose();
    }
}

Thus, manual memory management is important for resource control and preventing performance and stability issues.
