Net 4.0 Framework !!better!! 【FHD】

Version 4.0 was a complete rewrite. Microsoft discarded the previous runtime in favor of a leaner, faster engine that ran purely on the new TPL scheduler. The introduction of Flowchart workflows (alongside the existing Sequential and State Machine models) made complex business logic visual and accessible. For a time, this became the gold standard for building long-running business processes in sectors like finance and logistics. It was a significant investment by Microsoft in the "Low-Code" philosophy long before the term became a buzzword.
