Hi, 

I tried to use the class SignedXml in the Visual Studio 2008 Express framework, but it don't have this class.  I've installed the Service Pack1 and nothing..

Could anyone help me please?

Here is part of the program:

using System.Security;

using System.Security.Cryptography;
using System.Security.Cryptography.Xml;
using System.Security.Cryptography.X509Certificates;

protected void BtnEnviar_Click(object sender, EventArgs e)
{

// get certificate

....

// assinar XML
RSACryptoServiceProvider crypto = (RSACryptoServiceProvider)Certif.PrivateKey;

// Create a SignedXml object.
SignedXml signedXml = new SignedXml();

signedXml.SigningKey = crypto;

Reference reference = new Reference();

....

}

end of program

Thanks in advance!

Bye for now

Hi folks, 

You need to add the reference to System.Security.dll.

See http://msdn.microsoft.com/en-us/library/system.security.cryptography.xml.signedxml.aspx which shows that the assembly is System.Security.dll.

To add reference, click on the root in the Solution Explorer, and select >>Add Reference

Then on the tab .NET look up for System.Security.dll and click Ok

Then Rebuild the solution.

Bye
