Reading files asynchronously

In this section, we will read text from a file asynchronously. We will be building upon the code from the previous section that writes the text to a file asynchronously.

The following steps will add our asynchronous read method and update the Program.cs file to run our asynchronous code:

1. In the FileReadWriteAsync class, add the following method:

   public static async Task<string> ReadTextAsync()
   {
        string filePath = @"C:\Temp\Greetings.txt";
        using (FileStream fileStream = new FileStream(
                filePath,
                  FileMode.Open, 
                  FileAccess.Read,
