The result will be a class inheriting Telerik.Reporting.Report, that can be loaded in Visual Studio Report Designer.
In general, Telerik Reports are Telerik.Reporting.Report objects which can be serialized in TRDX files, or compressed TRDP files. The XML definition has a schema version that is updated in case of API changes in the released reporting functionality. It is important to use a version of Standalone Report Designer that matches the version of Telerik Reporting assemblies used to create the .NET report definition. For more information, please refer to XML Report Definition (XML Schema Versioning section). This guarantees that you are using the same version of Telerik Reporting engine to create and process reports.
