C# HttpClient Could not verify the provided CSRF token on a POST request

Question

I'm write here because I was trying to send a POST request to a server api,
I tried to send also another request(the first one) and from the response it work({"success":"true", "role":"USER"}). But in the sencond request as a response I get: {"timestamp":1524589409895,"status":403,"error":"Forbidden","message":"Invalid CSRF Token 'null' was found on the request parameter '_csrf' or header 'X-XSRF-TOKEN'.","path":"/api/v1/rec"}.
So I put all the cookies but one of them "XSRF -TOKEN" cause my program to crashSystem.Net.CookieException: The 'Name'='XSRF -TOKEN' part of the cookie is invalid
so I discovered that this cookie change every time you create a session
so I tried to get the cookies from the response of the first message and added on the header for the second one, and this is the result

I also set the NETFramework at the 4.5 version
I'm leaving a temporary account here for you so you can try this without creating an account only for a test
