I had the same issue. If your project is set to use the .NET 4.0 Framework, you must choose the right version of SvcUtil.exe, or it will throw an error: "Could not load..."

• If you look in "Microsoft SDKs\Windows\v6.0A\Bin", you will see that the version of that exe is "3.0.4506.2152".
• The version of SvcUtil.exe in "Microsoft SDKs\Windows\v7.0A\Bin" is exactly the same, so it threw me for a loop as well.

However, there is another version of SvcUtil.exe located in "Microsoft SDKs\Windows\v7.0A\Bin\NETFX 4.0 Tools" which is version "4.0.30319.1", and if you use it, everything should work.
