Visual Studio 2017 - PreBuild event command line (build another project) - visual-studio-2017

Question

I have a solution with multiple projects.
When I build project 'Foo', I need it to build also project 'SimplePluginFramework' before Foo.
It also needs to build 'SimplePluginFramework' in Release mode, even if Foo is built in debug mode.
I tried adding this to Foo's Pre-build event command line but it's existing with code 9009 and Bar doesn't get built...
$(MSBuildBinPath)\MSBuild.exe "L:\SL1 - Current System\Core\SL Agent\SLV1\Agent\SimplePluginFramework\SimplePluginFramework.csproj" /t:build /p:Configuration=Release
How can I make the build of one project trigger the build of a different project before the build?
I've tried adding a reference to that project but it still doesn't build it.

Project Dependencies:

Answer 1

Use Project | Project Dependencies to define that Foo depends on SimplePluginFramework.
Use solution configuration (right click on solution and select properties) to define that in solution level Debug configuration Foo's debug build is used but SimplePluginFramework's release build is used.
