c# - Disable cascade delete on a table globally for entity framework -

looking entity framework cascade delete. had cascade delete disable globally

        modelbuilder.conventions.remove<manytomanycascadedeleteconvention>();         modelbuilder.conventions.remove<onetomanycascadedeleteconvention>(); 

we wanting re enable it. problem comes when creating migration error "may cause cycles or multiple cascade paths".

the solution of using fluent api works create..

        modelbuilder.entity<campus>()             .hasrequired(c => c.institution)             .withmany()             .willcascadeondelete(false); 

however institution causes more 1 problem institutionid everywhere. want avoid having go through every option , ignore them case case. possible stop cascade delete relationships on institution table?

institution's never deleted don't mind if there isn't cascade delete on that.

thanks
