Changing Assembly Versions During Runtime Using the Web.Config File

For example, suppose you need to redirect a particular old version dll hit to a new version. The following code shows how to redirect from version 1.0.0.1 to 1.0.0.2:

  <runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="KeyvanAssembly"
                          publicKeyToken="de67da767df789acd"
                          culture="en-us" />
        <bindingRedirect oldVersion="1.0.0.1"
                        newVersion="1.0.0.2"/>
      </dependentAssembly>
    </assemblyBinding>
  </runtime>
