Thanks Amjad for the information.
Thanks for your posting and using Aspose.Cells for .NET.
First of all, we wish you a great 2013 year.
We are afraid, the version you mentioned is quite old, there has been many changes and enhancements since then, so it will not be fully back-ward compatible, you will have to upgrade your code and fix some compile time errors and warnings.
However, upgrading code will not be as difficult because most changes will occur creating and using Style objects. Earlier, there was a Cell.Style property but now it is replaced with Cell.GetStyle() and Cell.SetStyle() method.
