问：
I am trying to embrace the mysteries of SSL communication and have found a great tutorial on this site. I was trying to test my own certificate. Using Visual Studio 2012, I simply added an existing file (my certificate in .pfx format) and then changed the "certificate" and "password" settings in app.config. However, when trying to run it, I got an error:
CryptographicException was unhandled: System cannot find the specified file
Then, I tried the same in my Web Service. There I got some more details about the error:
System.Security.Cryptography.CryptographicException: System cannot find specified file. at System.Security.Cryptography.CryptographicException.ThrowCryptogaphicException(Int32 hr) at System.Security.Cryptography.X509Certificates.X509Utils._QueryCertFileType(String fileName) at System.Security.Cryptography.X509Certificates.X509Certificate.LoadCertificateFromFile(String fileName, Object password, X509KeyStorageFlags keyStorageFlags) v System.Security.Cryptography.X509Certificates.X509Certificate2..ctor(String fileName, String password) v TestServer.DataService.LoadSoap() v c:UsersAdministratorDocumentsVisual Studio 2012ProjectsTestServerTestServerDataService.asmx.cs:line 48
I have written this question to the author of the article, but since his last reply was in March 2012, I am not sure, whether he will reply. If somebody could help me with this problem, I would be very grateful.
P.S.: When exporting the certificate from .cer to .pfx, I have changed the title of the file exported. Although I doubt its effect on the problem, I'd rather mention it.

Did you set the following on the application pool in IIS?
- Go to IIS Manager
- Go to the application pool instance
- Click advanced settings
- Under Process model, set Load User Profile to true
See this stack question for further reading: What exactly happens when I set LoadUserProfile of IIS pool?
