Do you have any way to contact you? Would love to hear more about this. Also a C# developer and love EF. I think the standard library from Microsoft in general is the highest quality, most powerful and flexible library that’s out right now. I see so much potential to make a system that solves the 90% of use cases more simply, with enough flexibility to drop down lower when needed, and I think C# would be a great tool to build this.
Hey! It's exciting to see other's have similar ideas to boost productivity.
About the framework, I just read in a comment below about Java's Vaadin framework and it looks very similar to what I made in PHP. It's code that generate UI.
