Class DataSourceMetadataService

Namespace

ReportWright.Data

Assembly

ReportWright.Data.Abstractions.dll

What a designer asks a server about a report's data at design time: does the source answer, which fields does a dataset yield, what do a few rows look like. Every answer is a client-facing type with no connection text and no credential; the ResolvedDataSource never leaves this class.
