在本地计算机上（通过Visual Studio 2017或MSBuild）构建新的WebApi2项目时，我可以通过IISExpress或IIS运行应用程序。
但是，当我从团队的构建服务器（通过MSBuild）进行构建时，roslyn的输出目录中缺少以下特定文件：
Name
----
csc.exe.config
csc.rsp
csi.exe.config
csi.rsp
vbc.exe.config
vbc.rsp
VBCSCompiler.exe.config
我已验证在我的计算机和构建服务器上使用相同的参数调用了MSBuild。我还验证了它们都具有相同版本的MSBuild，并且都已安装.NET 4.7（我定位的版本）。
在roslyn目录中不存在上述config / rsp文件的情况下，我从IIS（截断的重复项）中收到以下错误：

我在这里做什么错了？
