I have been working with a Windows Mobile 6 app that is built with .NET Compact Framework 3.5 in Visual Studio 2008. The application builds incredibly slow, spending a majority of the time doing the PlatformVerificationTask.
How do I speed up the build?
The best way to stop the PlatformVerificationTask in a distributed development environment I would suggest adding the following to the mobile app's project file:
<Target Name="PlatformVerificationTask">
</Target>
This will overwrite the PlatformVerificationTask in \Windows\Microsoft.NET\Framework\v3.5\Microsoft.CompactFramework.Common.targets
This may be what IceSlurpy said about 10 hours ago.
For me to understand it, I simply "uncheck" the Build and Deploy projects that are not necessary.
If a Setup.CAB is part of your project, unchecking the Setup project can save a LOT of time!
