Ok, I have a very strange problem. I have a class library and I create a
windows forms application that uses it. I Publish it as a ClickOnce online
only setup. When I try to run it it fails the validation and I get:

System.Deployment.Application.InvalidDeploymentException (RefDefValidation)
        - Reference in the manifest does not match the identity of the downloaded
assembly MyLibrary.dll.

However, if I open the manifest file, I can see:

<dependency>
   <dependentAssembly dependencyType="install" allowDelayedBinding="true"
codebase="MyLibrary.dll" size="839680">
     <assemblyIdentity name="MyLibrary" version="1.0.0.0"
publicKeyToken="CD1B3EF0334774BA" language="neutral"
processorArchitecture="msil" />
     <hash>
       <dsig:Transforms>
         <dsig:Transform
Algorithm="urn:schemas-microsoft-com:HashTransforms.Identity" />
       </dsig:Transforms>
       <dsig:DigestMethod

       <dsig:DigestValue>utSMeQVcBCu2swZOvGyNc+YHXWI=</dsig:DigestValue>
     </hash>
   </dependentAssembly>
 </dependency>

And these are the EXACT identities of the assembly which I can see with
ildasm. Moreover, if I remove the .deploy and I run the application locally,
it works...

So, what gives? Why does the assembly fail validation??

Thank you,

Iulian
