Solution 1

Put your text cursor at the end of the word "SHA1CryptoServiceProvider" and a small hollow red block will appear underneath the right hand side of the word. Move the mouse over the block, and a drop down will appear with two options:

"using System.Security.Cryptography"

and

"System.Security.Cryptography.SHA1CryptoServiceProvider"

If you click the first one, it will insert the correct using statement, if you select the second, it will add the full namespace specification to the SHA1CryptoServiceProvider instance.

As if helping to use Google was not enough, shall we also need to help searching the standard .NET library? It could lead too far (should I say "nowhere"?)... :-)
My 5 though.

Yes, but in this case it allows me to tell him how to do it the easy way: via intellisense.

I would probably just shout "Google it!". This is a matter of seconds...

That's correct, a 5, but... sigh... please see my comment to Griff's answer?
