Cannot find the specified object using X509Certificate2

Question

I am trying to upload a file containing a private key to access Google Calendar API. Following this guide. For this, I created this code:

var certificate = new X509Certificate2("client_secret.json", "notasecret", X509KeyStorageFlags.Exportable);

I uploaded the file client_secret.jsoninside my solution, this is the file path:"...\Visual Studio 2015\Projects\Calendar\Calendar\bin\Debug\client_secret.json"

but it seems that the code cannot find the file and return this error:

Cannot find the specified object using X509Certificate2

I also set the property Always copyto Copy in the output directoryin the file to read.
