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
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>
其他回答
我在更新DotNetCompilerPlatform后也遇到了同样的问题。 通过重新启动Visual Studio >清理项目>构建项目解决。
我有webproject没有csproj文件和解决方案，这里提到的不适合我。
更改目标。net框架，重新安装包(Update-Package -重装)，然后构建项目对我来说很有效。你甚至可以在这个操作之后更改目标框架(确保你重新安装了nuget包)。
默认的VS2015模板的问题是编译器实际上没有复制到{outdir}_PublishedWebsites\tfr\bin\roslyn\目录中，而是复制到{outdir}\roslyn\目录中。这可能与您的本地环境不同，因为AppHarbor使用输出目录构建应用程序，而不是“就地”构建解决方案。
要修复它，在xml块<Target Name="EnsureNuGetPackageBuildImports" BeforeTargets="PrepareForBuild">
<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
打开项目文件，用Import project ="..\packages\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.1.0.0....删除所有引用
开放网络。配置并删除所有系统。代码dom编译器属性
