    Hi guys,

    For some reason when application tries to load signed XML into the
    SignedXml class using LoadXml method, then it generates next exception
    despite the fact that signed XML is valid. But it happens only in ASP.NET
    environement.
    Same code runs fine on a same PC if it is a Windows application. Anybody
    seen this before

    Exception has been thrown by the target of an invocation.
    at System.Reflection.RuntimeConstructorInfo.InternalInvoke(BindingFlags
    invokeAttr, Binder binder, Object[] parameters, CultureInfo culture, Boolean
    isBinderDefault) at
    System.Reflection.RuntimeConstructorInfo.Invoke(BindingFlags invokeAttr,
    Binder binder, Object[] parameters, CultureInfo culture) at
    System.Security.Cryptography.CryptoConfig.CreateFromName(String name,
    Object[] args) at
    System.Security.Cryptography.Xml.KeyInfo.LoadXml(XmlElement value) at
    System.Security.Cryptography.Xml.Signature.LoadXml(XmlElement value) at
    System.Security.Cryptography.Xml.SignedXml.LoadXml(XmlElement value) at
    VM.xPort.General.AddEntryToKeys(XmlDocument loXmlDocument, Hashtable loKeys,
    RSACryptoServiceProvider loRSAProvider, LicType lnLicType, String
    lcCurrentType)

    Code is pretty simple

    loSignedXml = New SignedXml()

    loSignedXml.LoadXml(loXmlDocument.GetElementsByTagName("Signature").Item(0))

    Thanks
