Asp.NET Identity 2 giving “Invalid Token” error

Question

I\'m using Asp.Net-Identity-2 and I\'m trying to verify email verification code using the below method. But I am getting an \"Invalid Token\"

Answer 1

Hit this issue with asp.net core and after a lot of digging I realised I'd turned this option on in Startup:

services.Configure(options =>
{
    options.LowercaseQueryStrings = true;
});

This of course invalidated the token that was in the query string.
