如何升级的MSBuild到C＃6？ [英] How to upgrade msbuild to C# 6?

问题描述

我想用C＃6在我的项目（​​空传播，其他功能）。

我已经在我的电脑上安装了VS 2015年和它出色的作品，并建立测试代码像

  VAR用户=新SingleUserModel（）; //所有模型字段为空
 VAR测试= user.User .Avatar [嗒嗒]？; 
  

但是，当我把我的项目回购和CI开始建造它，构建失败，因为不支持的？。

我已经安装了CI服务器上VS2015太多，但像looke它不使用它。
我能做些什么

CI - CruiseControl的.NET
与构建C：？\Windows\Microsoft。 NET\Framework\v4.0.30319\MSBuild.exe

解决方案

请确保你打电话

<预类=郎无prettyprint-覆盖> C：\Program文件（x86）\MSBuild\14.0\Bin \MsBuild.exe


这是的MSBuild的版本附带的Visual Studio 2015年和调用C＃编译器能够理解这一点。您可以通过安装Visual Studio 2015任何版本或安装独立的微软构建工具2015年。

添加到的following的NuGet包也将强制使用新的编译器的：

<预类=郎无prettyprint-覆盖> 安装封装Microsoft.Net.Compilers


I want to use C# 6 in my project (null propagation, other features).

I've installed VS 2015 on my PC and it works brilliantly and builds test code like

var user = new SingleUserModel(); //all model fields are null
var test = user.User?.Avatar?["blah"];

But when I push my project to the repo and CI starts to build it, build fails because of unsupported ?.

I've installed VS2015 on CI server too but looke like it doesn't use it. What can I do?

CI - CruiseControl .NET Builds with C:\Windows\Microsoft.NET\Framework\v4.0.30319\MSBuild.exe

解决方案

Make sure you call:

C:\Program Files (x86)\MSBuild\14.0\Bin\MsBuild.exe

That's the version of MsBuild that ships with Visual Studio 2015 and calls the C# compiler that understands this. You can get this version of MsBuild on your system by installing any edition of Visual Studio 2015 or by installing the stand-alone Microsoft Build Tools 2015.

Adding a reference to the following NuGet package will also force use of the new compiler:

Install-Package Microsoft.Net.Compilers
