MSBuild Task to read version of dll

I am looking for a MSBuild task that will tell me the version of a specific dll. Is there a task available for this?

In my case the dll is a .Net assembly, so I'm actually looking for Assembly.FullName.

• GetAssemblyIdentity is your man. This task outputs contain item metadata entries named Version, PublicKeyToken, and Culture.

  <ItemGroup>
      <MyAssemblies Include="File1.dll;File2.dll" />
  </ItemGroup>
  
  <Target Name="RetrieveIdentities>
      <GetAssemblyIdentity
          AssemblyFiles="@(MyAssemblies)">
          <Output
              TaskParameter="Assemblies"
              ItemName="MyAssemblyIdentities"/>
      </GetAssemblyIdentity>
  </Target>

• Thanks madgnome! I thought I would share the working code.

  <Target Name="UpdateWebConfigVersion">
   <GetAssemblyIdentity AssemblyFiles="lib\foo.dll">
    <Output TaskParameter="Assemblies" ItemName="fooAssemblyInfo"/>
   </GetAssemblyIdentity>
   <XmlUpdate XmlFileName="src\Web\ServiceModel.Extensions.config"
     XPath="//extensions/behaviorExtensions/add[@name='silverlightFaults']/@type"
     Value="foo.ServiceModel.Extensions.Behaviors.SilverlightFaultBehavior, foo, Version=%(fooAssemblyInfo.Version), Culture=neutral, PublicKeyToken=XXXXXXXX"/>
  </Target>
  

  quip : I make zip files in my build script, this helped me put the version number in the filename!!! Thanks!
