This code below thows the following error: System.Security.Cryptography.CryptographicException "The handle is invalid"

CspParameters CSPParam = new System.Security.Cryptography.CspParameters(13, null, null);
CSPParam.Flags = CspProviderFlags.UseMachineKeyStore;
CSPParam.KeyContainerName = "MyKeys";

System.Security.Cryptography.DSACryptoServiceProvider r = new System.Security.Cryptography.DSACryptoServiceProvider(CSPParam);  //Error occurs here

This code had been working with no issues then it started throwing this error. I can't think of anything that I have changed that relates to this. Has nayone seen this error? Any ideas of what to try?

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language.
