I'm currently using an msbuild file to copy some files to the public documents folder when my EXE is compiled. My current script includes this:
<Target Name="DeployToPublicDocuments"
Inputs="@(DeploymentItems)"
Outputs="$(PublicDocumentsFolder)%(Path)\%(DeploymentItems.RecursiveDir)%(DeploymentItems.Filename)%(DeploymentItems.Extension)">
<Copy SourceFiles="%(DeploymentItems.FullPath)"
DestinationFiles="$(PublicDocumentsFolder)%(Path)\%(DeploymentItems.RecursiveDir)%(DeploymentItems.Filename)%(DeploymentItems.Extension)"
Condition="!Exists('$(PublicDocumentsFolder)%(Path)\%(DeploymentItems.RecursiveDir)%(DeploymentItems.Filename)%(DeploymentItems.Extension)')" />
This code only copies if the destination doesn't exist. However, I want to replace the destination if my source is newer. How do I modify my script to make that happen? I see the SkipUnchangedFiles flag, but it also compares file size to determine if the destination should be overwritten. That is not what I want.
I think you may have misread the docs:
SkipUnchangedFiles
If true, skips the copying of files that are unchanged between the source and destination. The Copy task considers files to be unchanged if they have the same size and the same last modified time.

Your copy's conditional can be changed as follows:
<Copy SourceFiles="%(DeploymentItems.FullPath)"
DestinationFiles="$(PublicDocumentsFolder)%(Path)\%(RecursiveDir)%(Filename)%(DeploymentItems.Extension)"
Condition="%(Filename)!='' AND (!Exists('$(PublicDocumentsFolder)%(Path)\%(RecursiveDir)%(Filename)%(DeploymentItems.Extension)') OR $([System.DateTime]::Parse('%(ModifiedTime)').Ticks) > $([System.IO.File]::GetLastWriteTime('$(PublicDocumentsFolder)%(Path)\%(RecursiveDir)%(Filename)%(DeploymentItems.Extension)').Ticks))" />
%(ModifiedTime)
= Modified Datetime of the source file
$([System.IO.File]::GetLastWriteTime($(PublicDocumentsFolder)%(Path)\%(RecursiveDir)%(Filename)%(DeploymentItems.Extension)))
= Modified Datetime of the destination file, if it exists
Let me know if this works or not, did not test.
