Roslyn编译器在错误的bin文件夹中查找vbc.exe

Question

我真的很喜欢VS2015中VB14语言的新特性(比如?符号和字符串插值)。在我们的WinForms(。我使用codedom编译器动态地运行动态报告代码。遗憾的是，这并不自动支持新的语言特性。

Imports System.CodeDom.Compiler
Namespace MAF.DB.BusinessObject.ReportService
   Public Class VBReportCompiler
      Implements IReportCompiler
      Private ReadOnly ApplicationPath As String
      ''' <summary>
      ''' Create a report compiler with a reference to the location of the Wingman dlls. These need
      ''' to be referenced in the compilation, but the location differs between web and windows.
      ''' </summary>
      ''' <param name="ApplicationPath">Path to the binary folder</param>
      Public Sub New(ApplicationPath As String)
         Me.ApplicationPath = ApplicationPath
      End Sub
      Public Function Compile(convertedSourceCode As String, Optional ByRef reporter As IValidationReporter = Nothing,
                              Optional report As IBusinessObject = Nothing) As Object Implements IReportCompiler.Compile
         If reporter Is Nothing Then reporter = IOC.Dependency.Resolve(Of IValidationReporter)()
         Dim result As Object = Nothing
         Try
            If convertedSourceCode Is Nothing Then
               reporter.Add(report, "Report definition missing or blank")
            Else
               Dim params As New CompilerParameters With {
                  .GenerateExecutable = False,  ' Generate a DLL, not and EXE executable.
                  .GenerateInMemory = True,     ' Generate the assembly in memory, don't save to a file
                  .IncludeDebugInformation = True
               }
               params.TempFiles.KeepFiles = False ' don't keep temporary source files.
               ' Add a reference to necessary strong-named assemblies.
               With params.ReferencedAssemblies
                  .Add("Microsoft.VisualBasic.dll")
                  .Add("System.dll")
                  .Add("System.Core.dll")
                  .Add("System.Data.dll") 'Allows use in report of ADO data types
                  .Add("System.Data.DataSetExtensions.dll") 'Allows LINQ on DataTables
                  .Add("System.Drawing.dll") 'Allows access in report of GDI+ basic graphics functionality such as datatable
                  .Add("System.Xml.dll")
                  'Add References to required Wingman assemblies
                  .Add(IO.Path.Combine(ApplicationPath, "MAF.DB.dll")) 'Allows use in report of Data Access & Business Object functions and properties
                  .Add(IO.Path.Combine(ApplicationPath, "MAF.SharedClasses.dll"))
                  .Add(IO.Path.Combine(ApplicationPath, "DB.Foundation.dll"))
                  .Add(IO.Path.Combine(ApplicationPath, "MAF.Tracer.dll")) ' allows use in report of standard error messages
               End With
               ' Create the VB compiler.
               Dim provider = New VBCodeProvider() 'Use the current .Net Framework
               Dim compRes = provider.CompileAssemblyFromSource(params, convertedSourceCode)
               ' Check whether we have any compile errors.
               For Each compileError As CompilerError In compRes.Errors
                  reporter.Add(report, String.Format("Line {0}: {1}", compileError.Line, compileError.ErrorText))
               Next
               If reporter.Valid Then result = compRes.CompiledAssembly.CreateInstance("ReportCompiler")
            End If
         Catch ex As Exception
            reporter.Add(report, "Unknown Error: " & ex.Message)
         End Try
         If Not reporter.Valid Then Return Nothing
         Return result
      End Function
   End Class

为了让它工作，我已经尝试添加Roslyn codedom nuget包，但产生两个问题。

第一个问题是它在错误的地方寻找编译器bindebugbinroslynvbc.exe，而构建过程实际上在bindebugroslyn文件夹中创建它。谁能告诉我如何解决这个问题，因为它失败了我的构建服务器部署?

手动复制roslyn文件夹(解决方法)并将其放在codedom期望找到它的地方不是一个真正的解决方案，但这引发了第二个问题，它期望导入System.Web.HttpRequest和System.Web.HttpResponse。但我没有编译任何网络相关的代码(winforms)。那么它为什么会期待这个呢?

不承诺任何东西，但我有一个类似的问题，包括这些行(我正在升级-作为现有项目)在website.vbproj修复。
