A solution is a package of customized components that can be imported into a Microsoft Dynamics CRM 2011 system. Each solution has a name, version number, and publisher who owns the solution.
There are two primary purposes to using solutions:
Promoting your own customizations: Solutions can be exported from one Microsoft Dynamic CRM 2011 organization and imported into another. This is useful for promoting your customizations through your development, testing, and production deployments.
Obtaining independent software vendor (ISV) solutions: Solutions containing custom components can also be developed by third-party independent software vendors and imported into your organization. Solutions—whether they are free, for purchase or subscription—can be downloaded from the Microsoft Dynamics Marketplace or directly from ISVs' websites.
