msawczyn/EFDesigner

Provides a designer surface (.efmodel file format) for visual EF model creation with support for importing existing entities from C# source or compiled assemblies, then generates customizable code-first DbContext and POCO classes via T4 templates. Designed as a VS2019 extension that produces standard partial C# classes using the fluent API, enabling model regeneration without tool dependency while preserving manual code additions across generations.
