using System.IO; TempDirectory tempDir = new TempDirectory(); string tempDirectoryPath = tempDir.Path; // use tempDirectoryPath to store temporary files // ... tempDir.Dispose();In this example, a new TempDirectory instance is created which automatically generates a unique directory name. The path to the new directory is then retrieved using the `Path` property and stored in `tempDirectoryPath`. The temporary directory can then be used to store any files required, such as downloaded images or documents. Finally, the directory can be deleted using the `Dispose` method to clean up any temporary files and free up the disk space. The TempDirectory class is part of the `Microsoft.VisualStudio.TestPlatform.Client` package, which provides tools for unit testing in Visual Studio.
