This projects documents and tracks the progress of FileHelpers towards version 4.

Major Goals

targeting .Net 5
- maybe .Net Standard 2.0 or 2.1
- maybe compiling a subset to .Net Framework 4.0
Simplify maintenance
- dropping longtime deprecated features (Excel, ExcelNPOI, DataTable)
- moving classes to namespaces, directed and acyclic dependencies
- removing code generation through T4 templates. Technology is not known or widely used anymore.
Preparing more dynamic use of the library by splitting Attributes and Engine
not a goal
- async: we currently have to many engines. It is hard to change them. First we simplify (maybe unify) them and then use async / await and / or async streams.
- validation: I don't think this is the focus of filehelpers.
- Excel (with or without NPOI): for one, usage seems not high. maybe later reading / writing to file can be abstracted for text- and Excel files.

Version 4.0+

Add again dynamic feature, but without code generation. Instead offer a typed api.
Maybe add csv and dynamic detection again. Both depend currently on the dynamic feature.

Dropping and changing features will disturb longtime users.
- Mitigation through continuously up-to-date examples
