Can somebody please point me to a reference for the syntax of the expression language used in csproj / vbproj files within Visual Studio ? I've been seeing usages like the following :
<FilesForPackagingFromProject Include="%(CustomFiles.Identity)">
... and I'm trying to understand the '.Identity' bit.
The Identity bit is one of many MSBuild well-known item metadata.
It is essentially metadata of MSBuild Items.
You can use the metadata to Transform Item Types.
