SlSvcUtil does not generate code in Silverlight 4

I had a weired error today. We generate some of our Silverlight proxies using batch files calling slsvcutil (C:\Program Files\Microsoft SDKs\Silverlight\vX.0\tools). With Silverlight 3 everything was fine. After switching to Silverlight 4 the tool stopped generating code without any comment.

Found the solution here.

Simply put a SlSvcUtil.exe.config side by side with the exe with the following content:



<configuration>

  <satelliteassemblies>

    <assembly name="SlSvcUtil, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />

  </satelliteassemblies>

</configuration>

And immediately it works like a charm!

Have fun!
