Hi Richard. Thanks for the explanation ...much appreciated. As per your suggestion, I changed the code in the API so it returns BadRequest (400) when the registration fails. I rewrote my code as per your explanation above, but I the parsing of the response throws an exception

var problem = await response.Content.ReadFromJsonAsync<httpvalidationproblemdetails>();

I put a breakpoint and I see that the response variable catches the BadRequest(400) from the WEB Api but is throwing an exception
