Re: .Net RC - Could not create the XML transformation....

Yes, this is unfortunately something you need to change by hand with the 
current .Net frameworks; it is described in the README already.

change the  machine.config file (should be in 
C:\WINDOWS\Microsoft.NET\Framework\<version>\config) to add the 
following section:

<!-- Other configuration settings. -->
<mscorlib>
  <cryptographySettings>
    <cryptoNameMapping>
      <cryptoClasses>
        <cryptoClass 
exc14n="Microsoft.Web.Services.Security.XmlDsigExcC14NTransform, 
Microsoft.Web.Services"/>
        <cryptoClass 
exc14n.comments="Microsoft.Web.Services.Security.XmlDsigExcC14NWithCommentsTransform, 
Microsoft.Web.Services"/>
      </cryptoClasses>
      <nameEntry name="http://www.w3.org/2001/10/xml-exc-c14n#" 
class="exc14n"/>
      <nameEntry 
name="http://www.w3.org/2001/10/xml-exc-c14n#WithComments" 
class="exc14n.comments"/>
    </cryptoNameMapping>
  </cryptographySettings>
</mscorlib>

For those who don't edit XML files often, I usually get away with 
pasting this on the next to last line (right before "</configuration>"). 
This instructs the System.Security.CryptoConfig class on how to map the 
specified names to particular classes. It is unfortunate that the 
CryptoConfig class does not pay attention to the same section added to 
the local Web.config.
