       <Target Name="Default">
            <MSBuild Projects="@(AllFiles)"/>
       </Target>

2. Create batch file named BuildAll.cmd with following content: (change path to msbuild.exe depends on .NET Framework version you are using)

   C:\Windows\Microsoft.NET\Framework64\v4.0.30319\msbuild buildall.targets
   

3. Run/execute BuildAll.cmd
