Components of Solution

Solutions are comprised of a few core components. These components are created using the customization tools available or the APIs provided. These components are part of the following application:

All these solution components are available to be included in all solutions. They are defined in a solution exported as a ZIP file.

Opening such a solution file shows the following three XML files, as the following screenshot demonstrates:

The first file lists the available customized content types, if any. The solution.xml file contains the following elements:

With each solution created, a publisher is required. This is usually the partner or group providing the solution. This information is stored in a Publisher entity.

Dependencies are related solution items. For example, a component could require elements from another entity. This other entity does not necessarily have to be included in the solution. When it is not, a missing dependency is recorded in the solution. When deploying the solution, a check is done on the target system to determine whether the missing dependency is installed on the target by another solution. If it is not found, a missing dependency error is thrown and the installation is aborted.

The last element of a solution is the customizations.xml file. This is the meat of the solution, and it includes all the elements added to the solution. The document is structured by entity, but also includes details about the other solution components described earlier.

Analyzing the content of these XML files is beyond the scope of this book, but additional details about working with solutions can be found in the MSDN documentation available at the following website:
