I have a C# project A located in FolderA which references a shared project B. The files of the shared project are located in FolderB. The shared project B contains a file C.gz with the properties
Build Action: Embedded Resource
Copy to Output Directory: Do Not Copy
When I try to build project A using xbuild (specifically versions 4.8 and 4.8.1, x86 and x64 architectures):
I get the following build error:
C:\Program Files (x86)\Mono\lib\mono\xbuild\14.0\bin\Microsoft.Common.targets (CopyNonResxEmbeddedResources target) ->
C:\Program Files (x86)\Mono\lib\mono\xbuild\14.0\bin\Microsoft.Common.targets: error : Cannot copy FolderA\C.gz to FolderA\obj\Release\C.gz, as the source file doesn't exist.
i.e. xbuild searches for the embedded resource file in FolderA although it is apparently located in FolderB together with the other files of the shared project B.
With msbuild, project A builds without any issues.
We deprecated xbuild and recommend using msbuild instead. Switching to msbuild will also most likely resolve the issue you reported.
