更新后的问题为单声道4.0.1在Ubuntu [英] Issue after updating to mono 4.0.1 on Ubuntu

问题描述

我刚刚升级到的刚刚发布的单声道版本的 4.0.1 在我的Ubuntu的机器。单的previous安装的版本是3.2.7（如果我没记错的话）。

I just upgraded to the just released Mono version 4.0.1 on my ubuntu machines. The previous installed version of mono was 3.2.7 (if I remember correctly).

现在问题：

我的第一个问题是关于SignalR和自我托管。我有我的自我主机NancyFx，网页API和SignalR使用OWIN一个.NET 4.5.1控制台应用程序。当单3.2.7运行有就我所知，没有任何问题，但是当我尝试启动单声道4.0.1应用我得到以下堆栈跟踪：

My first issue is regarding SignalR and self-hosting. I have a .NET 4.5.1 console application in which I self host NancyFx, Web Api and SignalR using OWIN. When running on mono 3.2.7 there was no issues to my knowledge but when I try to start the application on mono 4.0.1 I get the following stack trace:

Unhandled Exception:
System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.InvalidProgramException: Invalid IL code in (wrapper delegate-invoke) <Module>:invoke_callvirt_CancellationTokenRegistration_CancellationToken&_Action`1<object>_object (System.Threading.CancellationToken&,System.Action`1<object>,object): IL_0057: castclass 0x00000007

我不知道什么这个错误可能意味着，我感激所有帮助。我使用微软ASP.NET SignalR自主机包2.2.0版本。

I have no clue to what this error could mean and I'm greatful for all assistance. I'm using Microsoft ASP.NET SignalR Self Host package version 2.2.0.

而作为一个侧面说明，我已经编制了新的单版本我所有的组件。

And as a side note, I've compiled all my assemblies on the new mono version.

亲切的问候，
西蒙

Kind regards, Simon
