Sample CI build definition using MSBuild

build.proj

<Project>
    <ItemGroup>
        <Solution Include="*.sln" />
        <PublishProject Include="XXX.Mvc\XXX.Mvc.csproj" />
        <TestProject Include="**\*.Test*.*proj" Exclude="XXX.Tests.Shared\XXX.Tests.Shared.csproj" />
    </ItemGroup>

    <Target Name="Build">
        <MSBuild Projects="@(Solution)" Targets="Restore" ContinueOnError="ErrorAndStop" UnloadProjectsOnCompletion="true" UseResultsCache="false" />
        <MSBuild Projects="@(PublishProject)" Targets="Publish" Properties="Configuration=Release" ContinueOnError="ErrorAndContinue" />
        <MSBuild Projects="@(TestProject)" Targets="VSTest" Properties="VSTestLogger=trx" ContinueOnError="ErrorAndContinue" />
    </Target>
</Project>

It works because the msbuild calls are done with different properties, which causes a forced re-evaluation of the project files.

wow @dasMulli that's some pretty epic MSBuild voodoo.
