No secret that the Microsoft .Net technology after a few years of development became widely known, and a wide circle of developers uses this technology for creating more powerful and up-to-date programs. The 9Rays.Net company was familiar with .Net since first beta versions of this technology were issued, and has been developing a constantly enlarging set of tools for .Net developers named Spices.Net. This wide set of actual, powerful, and universal tools is unexpendable for protecting, research, modeling, and analysis of .Net software. 9Rays.Net has announced a new version of Spices.Net - the version 5.0, which will undoubtedly capture the hearts of wide audience of .Net developers and researchers.
