I am trying to use NHibernate with Spring.Net und mySQL 5. However, when setting up the connection and creating the SessionFactoryObject, I get this InvalidCastException:
NHibernate seems to cast MySql.Data.MySqlClient.MySqlConnection to System.Data.Common.DbConnection which causes the exception.
System.InvalidCastException wurde nicht behandelt.
Message="Das Objekt des Typs \"MySql.Data.MySqlClient.MySqlConnection\" kann nicht in Typ \"System.Data.Common.DbConnection\" umgewandelt werden."

Is something missing? I downloaded the current mysql Connector from the mysql Website.
Shame on me, I downloaded accidently a wrong mysql connector and not the latest version: http://dev.mysql.com/downloads/connector/net/6.0.html
Sorry!

I'm attempting to use CryptUnprotectData to read a password protected using CryptProtectData into a SecureString and use that to connect to a database. I can get the correct password out, but trying to create a new SqlConnection after that fails with the following:

It's enough to simply call CryptUnprotectData for the SqlConnection to fail, the connection itself doesn't need to use the returned SecureString.
I'm using the extension methods from here as described in this post for my minimal repro:
class Program
{
const string ProtectedSecret = /* SNIP - base 64 encoded protected data here */;
static void Main()
{
// calling AppendProtectedData breaks the following SqlConnection
// without the following line the application works fine
new SecureString().AppendProtectedData(Convert.FromBase64String(ProtectedSecret));
using (var conn = new SqlConnection("Server=(localdb)\\MSSqlLocalDb;Trusted_Connection=true"))
using (var cmd = new SqlCommand("select 1", conn))
{
conn.Open();
cmd.ExecuteNonQuery();
}
}
}
If i create a new SqlConnection before I load the password, I can create new SqlConnections fine for the duration of the application as it seems to use the same SqlConnectionFactory, but that means as a workaround I have to do something like this at the start of the application:
new SqlConnection().Dispose();
... which I'd like to avoid.
The following do not help:
Debug vs Release build
Debugging in Visual Studio vs running through the command line
Changing the CryptProtectFlags that is passed to CryptUnprotectData.
Removing RuntimeHelpers.PrepareConstrainedRegions() from the protection method.
Windows 10, VS Enterprise 2015, Console Application (.NET 4.6.1)
UPDATE: Running the data protection code in another threads gives a similar exception with a different root cause:

Interestingly the faulting code is:
internal static PerformanceCounterLib GetPerformanceCounterLib(string machineName, CultureInfo culture) {
SharedUtils.CheckEnvironment();
string lcidString = culture.LCID.ToString("X3", CultureInfo.InvariantCulture);
if (machineName.CompareTo(".") == 0)
machineName = ComputerName.ToLower(CultureInfo.InvariantCulture);
else
machineName = machineName.ToLower(CultureInfo.InvariantCulture);
...
the line that calls ComputerName.ToLower(CultureInfo.InvariantCulture) causes the exception.
You can reproduce the same behavior just calling code
new SecureString().AppendProtectedData(Convert.FromBase64String(ProtectedSecret));
string lower = "Something".ToLower(CultureInfo.InvariantCulture);
Somehow in the constructor of the TextInfo class
this.m_dataHandle = CompareInfo.InternalInitSortHandle(m_textInfoName, out handleOrigin);
returns invalid data if this is not called before CryptUnprotectData function.
This seems like a bug in the framework. You can submit it to Microsoft. In the meantime you can call this line beforehand to prevent the error.
"".ToLower(CultureInfo.InvariantCulture);
I was recently experiencing similar symptoms, using the same code from http://www.griffinscs.com/?p=12: any call to CryptUnprotectData would lead to an exception in some unrelated code. Interestingly, the failure only occurred on a Windows 10 machine; the same code worked fine on a Windows 7 machine.
I fixed the problem by changing the declarations of the szDataDescr parameters in both CryptProtectData and CryptUnprotectData from string to IntPtr, and passing IntPtr.Zero instead of string.Empty in the two calls.
when i try to implement a consumer like the example mentionened in readme section the following
line
var config = new Config() { GroupId = "example-csharp-consumer" };
causes this exception

I get the error at the end when I try to start a project I'm working on from Visual Studio. It worked fine until a few hours ago. After some minor unrelated changes it stopped working when starting from Visual Studio. It works fine when run from explorer. Even old version vom revision control (where this part of the code is exactly the same and has worked without any problems) behave the same way so it doesn't seem to be a problem in my code.
The code at Program.cs:line 14 is the following:
private static NLog.Logger logger = NLog.LogManager.GetCurrentClassLogger();
Any ideas on how to solve this?
