I am not sure that I am asking right question. But I have a suspicion that I can build a .net solution file for a mac computer. Please let me know if I can. Also the pros and cons.
Thanks
Mono is one option, but depending on what parts of the .NET framework you need Silverlight might be an option as well. Mono is an open source project, which always has to chase Microsoft from behind, while Silverlight for Mac is a Microsoft release.
If you can live with the limitations of Silverlight, I'd definitely choose it instead of Mono. If you go the Mono way, be sure to test your application with Mono early and often, as there are incompatibilities.
