c# - Entity Framework Save not working -

i using entity framework save info in sqlite database file.

this table in db file

id name username pwd

id autoincrement, , rest of columns of text type

this how saving info database:

userinfo userinfo=new userinfo(); userinfo.name="abc"; userinfo.username="xyz"; userinfo.pwd="123456"; using (var context = new applicationcontext()) { context.userinfo.add(userinfo); context.savechanges(); }

the problem is, code not inserting new row table. tried before saving, no luck

context.entry<userinfo>(userinfo).state = entitystate.added; context.changetracker.detectchanges();

i tried debugging , no exception occurring.

how can insert new row table using entity framework?
