What is a solution package?
* A solution package is a distribution package that delivers your custom SharePoint Server 2010 development work to the Web servers or the application servers in your server farm. Use solutions to package and deploy custom Features, site definitions, templates, layout pages, Web Parts, cascading style sheets, and assemblies. * You can deploy a Microsoft SharePoint Server 2010 solution directly onto your SharePoint Server farm, or you can deploy the solution into a sandbox. A sandbox is a restricted execution environment that enables programs to access only certain resources, and that keeps problems that occur in the sandbox from affecting the rest of the server environment. A solution package is a CAB file with a . wsp file name extension and a manifest file . * It is recommended that you use Visual Studio 2010 Tools for SharePoint 2010 to develop and package SharePoint solutions. You can also create solution packages manually by using a tool such as Makecab.exe . Compo
