问题 I use a makefile to compile my C# project. In this makefile, I create a library tools.dll calling csc.exe, OK. Now, I want to use this .dll in my project. For some reasons, I have to use MSBuild.exe which use .csproj file. In .csproj file I added this section : <Reference Include="TOOLS"> <HintPath>C:\Gen\Lib\TOOLS.dll</HintPath> </Reference> That's works fine ! But my question is : How can I add tools.dll reference from MSBuild command line ? I need that, to call MSBuild.exe in makefile and
