This change is also required for the 'Release|x64' configuration,
otherwise 'Release' builds fail.

Also, it appears the newer version of the compiler (combined with the
new version of WDK/SDK), requires that the driver signing process
mandate a File Digest Algorithm (using the /fd option). It is a
warning today, but they claim it could become a requirement in the
future.
To fix this, we can include the following in the project file:
<DriverSign>
<FileDigestAlgorithm>SHA256</FileDigestAlgorithm>
</DriverSign>
Or set the above, using project 'Properties'->Driver Signing->File
Digest Algorithm = 256.
Should be:
"Or set the above, using project 'Properties'->Driver Signing->File
Digest Algorithm = SHA256"
(This will need to be fixed in the netuio driver project also)
