Build error due to Async BCL packages without VS 2012 on a CI server (Team City)

Question

I develop an application that has to run on Windows XP (so the .Net Framework has to be 4.0). I need to reference Async BCL packages in order to use async/await in some of my projects.

I have correctly referenced the following packages to the targeted projects as mentioned by ThomasArdal in his answer ( Async Targeting Pack without Visual Studio 2012 on BuildServer ):

Microsoft.BCL

Microsoft.BCL.Async

Microsoft.BCL.Build

Unfortunately the build fails when it is run from TeamCity on my CI server (running Microsoft Windows Server 2003) because async/await keywords are not recognized:

Member modifier 'public' must precede the member type and name

Do you have any clue that could help me to solve this issue ?

Answer 1

您的CI服务器必须使用最新的msbuild.exe（来自.net 4.5）
