Why does msbuild try to copy from wrong path? - msbuild

Question

I try to build Windows Store app using MSBuild.
C:\Windows\Microsoft.NET\Framework\v4.0.30319>MSBuild.exe /t:build /p:Configurat
ion=Release;Platform=x86 E:\MyApp.W8.csproj /logger:FileLogger,Microsoft.Build.Engine;logfile=E:/log/test.txt /p:OutputPath=E:/result
And I got this error:
"E:\MyApp.W8.csproj
" (build target) (1) ->
(CopyGeneratedXaml target) ->
C:\Program Files (x86)\MSBuild\Microsoft\WindowsXaml\v12.0\8.1\Microsoft.Wind
ows.UI.Xaml.Common.targets(476,9): error MSB3021: Unable to copy file "obj\x86\
Release\E:\MyApp.Shared\App.xbf" to "E:\result\E:\MyApp.Shared\App.xbf". The given path's format is not
supported. [E:\MyApp.W8.csproj]
I don`t know why MSBuild tries to use
obj\x86\Release\E:\MyApp.Shared\App.xbf
instead obj\x86\Release\App.xbf
or absolute path to App.xbf.

According to this post, inside your .projitems file you'll find the following code:
<ApplicationDefinition Include="$(MSBuildThisFileDirectory)App.xaml">
<SubType>Designer</SubType>
</ApplicationDefinition>
Replace this with:
<ApplicationDefinition Include="$(MSBuildThisFileDirectory)App.xaml">
<SubType>Designer</SubType>
<Link>App.xaml</Link>
</ApplicationDefinition>
