byte[] bytes = System.Text.Encoding.UTF8.GetBytes("example string");

Bastard Programmer from Hell
If you can't read my code, try converting it here[^]

byte[] bytes = System.Text.Encoding.UTF8.GetBytes(myString);
File.WriteAllBytes(path, bytes);

File.WriteAllText(sampleFile, stringContent, System.Text.Encoding.UTF8);

To be perfectly honest its my experience that EF is a cool toy for pulling reports or nested data (Pull a Customer and have all his orders in a single call)
HOWEVER if performance is in any way a consideration for the application Avoid EF like the plague.
