I created a class library as a separated project and after compiling it, I tried to access in another project but with no success.

using system;
using myProject;

namespace otherproject
{
   public class MyOtherProject
   {
      // I want to access properties and methods of MyProject.DLL here but   
      //like:
      GetTax getTax = new GetTax();
      getTax.ComputeTax(blah....);
   }
}

Above gives an error C:\DotNetApps\OtherProject.cs(6): The type or namespace name 'myProject' could not be found (are you missing a using directive or an assembly reference?)

Please help!

TIA
