我正在尝试运行ASP。NET MVC(模型-视图-控制器)项目从TFS (Team Foundation Server)源代码控制检索。我已经添加了所有程序集引用，我能够成功地构建和编译，没有任何错误或警告。
但是我在浏览器中得到以下错误:
找不到路径的一部分 “C: \ B8akWorkspace \ B8akProject \ B8akSolution \ B8AK.Portal \ bin \ roslyn \ csc.exe”。
以下是错误页面的完整截图。
经过几天的研究，我了解到Roslyn是一个提供高级编译特性的. net编译器平台。但是，我不明白为什么我的构建试图找到\bin\roslyn\csc.exe，因为我没有配置任何与roslyn相关的东西。我也没打算让罗斯林参与我的项目。
当前回答
对于那些在编译服务器(TFS或Bamboo)上编译时遇到这个问题的人来说，我能够通过从“/t:”msbuild选项中删除“clean”选项来解决这个问题。
其他回答
要做到这一点，可以采用以下简单的方法:
在系统的任何地方创建一个类似类型的新项目。构建它并将roslyn文件夹复制到bin目录。
这是Microsoft.CodeDom.Providers.DotNetCompilerPlatform 1.0.6的一个已知问题。降级到1.0.5为我解决了这个问题。

将PropertyGroup添加到.csproj文件中
<PropertyGroup>
<PostBuildEvent>
if not exist "$(WebProjectOutputDir)\bin\Roslyn" md "$(WebProjectOutputDir)\bin\Roslyn"
start /MIN xcopy /s /y /R "$(OutDir)roslyn\*.*" "$(WebProjectOutputDir)\bin\Roslyn"
</PostBuildEvent>
</PropertyGroup>
The answer for this is different for Website project and Web application Project. The underlying issue is same that NuGet package is behaving differently on different machine. It may be rights issue or some execution policy which stops it from copying to Bin folder As you know Roslyn is new compiler. you should have it in Bin folder for these Projects Go to your website NuGet Packages check this Folder Microsoft.CodeDom.Providers.DotNetCompilerPlatform.2.0.0 \code\packages\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.2.0.0 Do you see it ? Can you see code\packages\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.2.0.0\tools\RoslynLatest in it Now as part of compiling this Folder should get copied to your website under bin like this. \code\WebSite1\Bin\Roslyn some how that is not happening for you . Try running Visual studio as Admin . Copy Roslyn folder manually. Try uninstall and install of NuGet Package. Remember this package compile your folder and if its not there you cannot compile anything and so you cannot add anything too. Try copying this package to offline version tools -> options-> nuget package Manager->Package source-> Microsoft Visual Studio Offline Packages C:\Program Files (x86)\Microsoft SDKs\NuGetPackages
