I'm trying to implement fusion auth authentication for a WPF application. I used OIDC Client to implement Browser login but I'm getting Malformed Callback URL, I tried keeping every url I have used a WEB API, I have used working website a callback URL, even I tried keeping Google.com as callback URL still I got same Malformed Callback URL error. In another sample I have implemented authentication using HTTP but I'm getting 400 error if I connect to Development environment fusion auth url but I'm getting 200 success response if I use my localhost fusion auth url. I was able to implement fusion auth in .net MVC application using the Nuget package Fusionauth Client but I'm getting error if I tried it in my WPF application.
