Compile class without VS Studio .Net

[BukHix]

I have Visual Basic Standard Edition, which as far as I can tell, will not compile classes into a dll's (through the gui anyway). I know it can be accomplished using the VBC.exe and some command line arguments but I am not sure which arguments I should be using.

I thought this would work (a modified version of something I found on the Internet) but it doesn't.

vbc /t:library /r:System.dll class1.vb

It give me errors on every line. Is it because I don't have any Imports in the class? Is there a better way to do this?

By the way, this is how my class looks:

Public Class Class1
    Function about() As String
        Dim str1 As String = "About ClassLibrary1" & _
            StrDup(2, vbCr) & _
            "This is my story" & vbCr & _
            "This is my song."
        Return str1
    End Function
End Class

Just in case you are wondering this is a sample from a learn VB.Net book.
