entity framework - What is the purpose of .edmx files? -

-

what purpose of .edmx files? reading csdl, ssdl, , msl specifications, looks me .edmx files used @ design time. meant distribute other edmx? seems need distribute .ssdl and/or .csdl files instead.

edmx visual studio's "container" things entity data model.

it contains information in csdl, ssdl, msl, plus information visual layout of tables in visual studio designer surface.

the edmx file converted csdl, ssdl, msl (typically embedded resources in assembly) during build process. don't have distribute or copy edmx files anywhere app run.

update: if more interested in code-based approach, should check out code-first ctp entity framework gets without .edmx, .csdl/ssdl/msl files @ all.
