Just uploaded a new Minimod for simple generation of CSV files from a MvcControllers’ action with the help of CsvHelper.
Usage
return new CsvHelperFileResult<RecordType, RecordCsvMap>(records, ";") { FileDownloadName = "my-csv-file.csv" };
Find the source code here: CsvHelperMvcActionResult
BTW: Minimods uses nuget to distribute helper-classes as source code instead of compiled libraries.
