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
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>

这里有一个更MSBuild的方法。
<Target Name="CopyRoslynFiles" AfterTargets="AfterBuild" Condition="!$(Disable_CopyWebApplication) And '$(OutDir)' != '$(OutputPath)'">
<ItemGroup>
<RoslynFiles Include="$(CscToolPath)\*" />
</ItemGroup>
<MakeDir Directories="$(WebProjectOutputDir)\bin\roslyn" />
<Copy SourceFiles="@(RoslynFiles)" DestinationFolder="$(WebProjectOutputDir)\bin\roslyn" SkipUnchangedFiles="true" Retries="$(CopyRetryCount)" RetryDelayMilliseconds="$(CopyRetryDelayMilliseconds)" />
</Target>
但是我注意到roslyn文件也在我的bin目录中(而不是在文件夹中)。不过，这款应用似乎还能用。
仅供参考……
截至2017年8月31日，升级到Microsoft.CodeDom.Providers.DotNetCompilerPlatform 1.0.7是有效的。
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
下面为我解决了这个问题:
更新到Visual Studio 2017的最新版本(使用安装程序应用程序) 清理并重新构建解决方案
默认的VS2015模板的问题是编译器实际上没有复制到tfr\bin\roslyn\目录中，而是复制到{outdir}\roslyn\目录中
在.csproj文件中添加以下代码:
<Target Name="CopyRoslynFiles" AfterTargets="AfterBuild" Condition="!$(Disable_CopyWebApplication) And '$(OutDir)' != '$(OutputPath)'">
<ItemGroup>
<RoslynFiles Include="$(CscToolPath)\*" />
</ItemGroup>
<MakeDir Directories="$(WebProjectOutputDir)\bin\roslyn" />
<Copy SourceFiles="@(RoslynFiles)" DestinationFolder="$(WebProjectOutputDir)\bin\roslyn" SkipUnchangedFiles="true" Retries="$(CopyRetryCount)" RetryDelayMilliseconds="$(CopyRetryDelayMilliseconds)" />
</Target>
