Hello Friends. I need a super duper expert for the following two tasks. 1. I created and authorized a user via oAuth on winform application, now i am trying to read programs for that user, the httpclient giving me correct record, but await, async not waiting for to parse that data by Jsonconvert. i need some one who can explain me what i am doing wrong. pretty simple task will not take more than 30 mints for an expert. 2. second task is i have a .net core MVC web project i am using it with Entity Core framework. i only need you to add a record into a table via ajax call. all the code is writing the system retrieving and reading data but only not inserting/updating the records. and this call should be ajaxify. that's it i am welling to pay $20 for these task. pretty simple
