Xamarin.Forms便携式类库项目与Sharp.XMPP库 [英] Xamarin.Forms Portable Class Library Project with Sharp.XMPP library

问题描述

针对具体问题已发生在我的项目。我已经找到了C＃支持的Andr​​oid（在Xamarin）仅一个库： Sharp.XMPP ，< A HREF =htt​​ps://www.nuget.org/packages/Sharp.Xmpp/相对=nofollow>的NuGet ，但我有它的烦恼。当我写在分开的便携式类库的一些示例code，我得到这些错误：

an specific issue has occured in my project. I've found only one library for C# supporting Android (in Xamarin): Sharp.XMPP, NuGet, but I have troubles with it. When I write some sample code in separated portable class library, I get these errors:

Error 1: '.ctor' is not supported by the language

而行

using (XmppClient client = new XmppClient(hostname, username, password))
            {
              ...
            }

下一页：

Error 2: Metadata file '...\Project.Jabber.dll' could not be found  
Warnings 2-6: Reference to type 'System.Net.Security.RemoteCertificateValidationCallback' claims it is defined in 'c:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETPortable\v4.5\Profile\Profile78\System.dll', but it could not be found   c:\Users\Kliford\Downloads\S22.Xmpp\S22.Xmpp.dll 

我无言以对。
谢谢你在前进。

I am clueless. Thank you in advance.

推荐答案

Sharp.Xmpp 是不是与 PCL兼容，因为它使用的的XmlElement 类，它目前还不可用 PCL 。

Sharp.Xmpp is not compatible with PCL since it uses the XmlElement class, which is not currently available in PCL.

重写这部分是可行的，但需要显著努力。

Rewriting this part is doable, but requires a significant effort.

这是我使用的解决方法，是制定 .NET 4.5 类库，它引用 Sharp.XMPP 。 的Windows之间的可移植性和净通过 Xamarin 实现。

The workaround that I use, is to develop .Net 4.5 Class libraries, which reference Sharp.XMPP. Portability among Windows and .Net is achieved through Xamarin.
