(wrapper dynamic-method) system.object:51155536-39dc-466e-a95f-dea6c3e2125b (intptr,intptr) one of queries failes is:
var list = await contactrepository .getall() .where(x => x.isme) .tolistasync(); when remove clause works.
another solve when changed following:
query.where(x => x.infos.any()) .where(x => x.infos.any(e => e.infotype.tostring() .startswith("number", stringcomparison.ordinalignorecase))); to:
query.where(x => x.infos.any(e => e.infotype.tostring() .startswith("number", stringcomparison.ordinalignorecase))); i use ef core 1.1.2 , ef core sqlite 1.1.2.
since there update ef core 2.0 thought maybe fixable update. ef core supported xamarin.android 7.5 right not available. update not possible..
i talked other developer have similar isses. what's wrong here , how can fix that?
this issue fixed in vs 15.3.2
