but i want to exclude column when edmx file is created i.e when i connect my database using Ado.net Data modal option i want few columns to be excluded from edmx as if they don't exists in database. currently i am exploring the entity framework source code but cannot find the exact code that generates .edmx file and store.
example: suppose i have a column "SysStartDate" now i want to exclude this column from all the table having it.
i want to exclude columns from edmx so .csdl ,.msdl, and *.ssdl file doesn't include it.
