Issue with using MSBuild to build and copy all outputs to a common folder

Question

We are trying to write a msbuild script that will build the solution and copy over all the compiled binaries and dependencies over to a specific output folder. While the build script that we have does build and copy over the binaries to a common folder, but we are not getting the dependencies copied. This probably has to do with the way we have used the msbuild task to build the solution and we are accepting the targetoutputs of the task into an itemgroup and iterating over the item group to copy all the compiled dlls and exes over to a common folder. But this is not including the dependency dlls which gets placed into the individual bin folder of each project.

<Project ToolsVersion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
<PropertyGroup>
    <ParentSolutionFile />
</PropertyGroup>
<ItemGroup>
    <Assemblies Include="*.dll, *.exe" />
</ItemGroup>
<Target Name="BuildAll">
    <CombinePath BasePath="$(MSBuildProjectDirectory)" Paths="Source\Solutions\xxx.sln">
        <Output TaskParameter="CombinedPaths" PropertyName="ParentSolutionFile" />
    </CombinePath>
    <Message Text="$(ParentSolutionFile)" />
    <MSBuild Projects="$(ParentSolutionFile)">
        <Output TaskParameter="TargetOutputs" ItemName="Assemblies" />
    </MSBuild>
    <Message Text="%(Assemblies.Identity)" />
    <Copy SourceFiles="%(Assemblies.Identity)" DestinationFolder="$(MSBuildProjectDirectory)\Binary" OverwriteReadOnlyFiles="True" SkipUnchangedFiles="True" />
</Target>

What will be the preferred way to copy over all the binaries along with the necessary dependencies to a common output folder?

Answer 1

Does not overriding OutputPath do the trick alone?

<MSBuild Projects="$(ParentSolutionFile)" Properties="OutputPath=$(MSBuildProjectDirectory)\Binary">
  <Output TaskParameter="TargetOutputs" ItemName="Assemblies" />
</MSBuild>

And leave out the copy task alltogether?
