I am using Visual Studio 2017 to design a SSRS report. Are some of the error messages one sees when they click on the Preview button actually meaningless? For example, I get, "The tablix 'Tablix2' is invalid. The value for the DataSetName property is missing." But when I look at the xml for the rdl file, I can not find any "Tablix2".
Report Properties are empty. When I build, there are no errors or warnings
