我正在尝试将我的网站从dotnet核心rc1迁移到dotnet核心rc2，但我遇到了一个错误，然后我尝试运行一个小测试，它也不适用于我。 这是我的箴言：https://github.com/ricardoalcantara/WebApplicationBasic
我的环境是：
我需要在“框架”：“net451”之上运行它，因为我的主项目需要很少的库仍然只能在该平台上运行，所以我使用这个命令行运行：
dotnet run --framework .NETFramework,Version=v4.5.1
它实际上运行，但是当我尝试访问localhost：5000时，它会主要使用该消息抛出一个长堆栈错误：
z2cw6v06.4ja(43,10): error CS0518: Predefined type 'System.Object' is not defined or imported

有人可以帮我解决这个问题吗？

如果仔细观察，错误似乎是MVC无法编译视图：
Microsoft.AspNetCore.Mvc.Razor.Compilation.CompilationFailedException: One or more compilation failures occurred:
pufduf6v.a1v(17,88): error CS1980: Cannot define a class or member that utilizes 'dynamic' because the compiler required type 'System.Runtime.CompilerServices.DynamicAttribute' cannot be found. Are you missing a reference?
pufduf6v.a1v(17,88): error CS0518: Predefined type 'System.Boolean' is not defined or imported
pufduf6v.a1v(17,47): error CS0012: The type 'Object' is defined in an assembly that is not referenced. You must add a reference to assembly 'mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.

但是运行dotnet publish然后使用mono直接执行结果对我有用，例如（在Ubuntu上）：
mono bin/Debug/net451/ubuntu.14.04-x64/publish/WebApplicationBasic.exe
As was already explained to you on Github, this seems to be a known issue.
