BE0072: Project framework version 'XXXX' not found. It has been redirected.
Warning BE0072: Project framework version ' XXXX ' not found. It has been redirected and will use ' YYYY ' instead.
Cause
The build engine was unable to locate framework information for the version specified in the
project's FrameworkVersion property. A later version of the framework was found and
will be used instead.
Solution
If you require the earlier version of the framework, it must be installed on the system.
