问题描述

我刚刚在我的 ubuntu 机器上升级到 刚刚发布的 Mono 版本 4.0.1.之前安装的 mono 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).

现在的问题:

我的第一个问题是关于 SignalR 和自托管.我有一个 .NET 4.5.1 控制台应用程序，我在其中使用 OWIN 自托管 NancyFx、Web Api 和 SignalR.在 mono 3.2.7 上运行时，据我所知没有问题，但是当我尝试在 mono 4.0.1 上启动应用程序时，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:

我不知道这个错误可能意味着什么，我非常感谢所有帮助.我正在使用 Microsoft ASP.NET SignalR Self Host 包版本 2.2.0.

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.

顺便说一句，我已经在新的单声道版本上编译了我的所有程序集.

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

亲切的问候，西蒙
