Even after googling I could not solve the below problem when I try to  
run ruby script from C# .NET using VS2010. Please help

Could not load file or assembly ‘Microsoft.Scripting, Version=0.9.6.20,  
Culture=neutral, PublicKeyToken=31bf3856ad364e35’ or one of its  
dependencies. Strong name validation failed. (Exception from HRESULT:  
0x8013141A)

What IronRuby binaries do you use? Did you install 1.0 using  
IronRuby.msi?

The error means that Microsoft.Scripting assembly is delay-signed and  
you didn’t suppress strong name validation via sn -Vr \*,31bf3856ad364e35  
(see [Strong Name Tool (Sn.exe) | Microsoft Learn](http://msdn.microsoft.com/en-us/library/k5b5tt23(VS.80).aspx))

I could successfully compile now, after I downloaded the dll’s again  
from the  
website mentioned below
