OPTIONS requets returns 400 error while adding openiddict to asp.net core api

hi Do I need to enable cors on OpenIddict separately? because I thought adding the following codes will handle the cors but as soon as Chrome want to send an options request, my app returns 400!

services.AddCors(); and app.UseCors(builder => builder.AllowAnyHeader() .AllowAnyMethod() .AllowAnyOrigin() );

I dont know If i need to add something else or not!

the configuration of openiddict is exactly as same as what I read from the wiki section if this project on github. and the project specifications are mentioned below

ASP.net Core v1.1 Client side : SPA Angularjs App using JWT Token

any help ?

You do.

Here is the configuration of openIdDict , it may help

You must register the CORS middleware before OpenIddict.

Don’t forget to update your CORS policy to use specific origins (AllowAnyOrigin is not safe).
