This is a tool for XRMToolBox. The purpose of the tool is to view a historical list of solutions that have been imported. This provides sort of audit functionality for solutions, as the OOB solution view doesn't really display how many times a solution has been imported, version number that was updated, error/warning messages that were encountered during solution import. This tool uses importjob entity to get list of solution imports and RetrieveFormattedImportJobResultsRequest message to save the import solution file details.
