All the AssemblyInfo.cs files in the code download have the following line 
in it:

[assembly: AssemblyKeyFile(@"\Wrox\Keys\ThePhile.snk")]

When I translate this to VB.NET

<Assembly: AssemblyKeyFile(@"\InformaNET.SNK")> 

the IDE reports the error: "Invalid character" for the @ symbol. Any idea 
on how to correct this?
