问题 I am trying to upgrade my pcl library to target the netstandard in Xamarin Studio on my Mac. But I don't see the option. All the information I have found only talk about using Visual Studio. Xamarin Blog Oren's blog When I look for the option they talk about in Xamarin Studio, I can't find it. 回答1: As of Xamarin Studio 6.0.2 you can consume .Net Standard libs, but NOT create them.

问题 I have existing .Net libraries which work already for .Net 4.5 and Windows Phone 8. Now I would like to convert this in a portable class library and suddenly I can't use System.Net.Sockets anymore. I only cheched .Net 4.5 and windows phone 8. Xbox/store app/silverlight is not selected. Xamarin is automaticly selected because it has the same requirements. I can avoid sockets by using interfaces and stuff, but why can't I use it if they both support it? There are other questions on

It has a property in it called ViewModels , which is of type Dictionay<K, V> Then I have a Windows Phone 8 project that references the portable class library.

问题 I have following problem. I use Portable library in my UWP application (Portable library is shared with Xamarin app). This portable library references SQLite. In this Portable library I also use Prism and Unity. For that reason I still can't upgrade them to .NET Standard. SQLite library I use is SQLite-net-pcl version 1.4.18. In my UWP app I add same nugget package. The problem is that this nugget package also support .net standard, as result, when I build my UWP library, I got different

问题 What are the steps required to make the two items available in the Add Portable Class Library dialog? 回答1: Please see my answer in Creating a PCL that targets Monodroid In the meantime, there are quite a few blog posts around on how to get PCLs working unofficially - eg.: http://blogs.endjin.com/2013/05/xamarin-platform-setup-gotchas/ http://slodge.blogspot.co.uk/2013/04/my-current-pcl-setup-in-visual-studio.html 来源： https://stackoverflow.com/questions/16678066/xamarin-support-in-add-portable

问题 I was looking to see if the Async CTP with a portable class library? 回答1: No. The Async CTP has different dlls for Desktop, Phone, Silverlight 4, and Silverlight 5. Hopefully in the near future, all these platforms will support Task (and async) natively, and then portable class libraries would be able to use async. Update: Microsoft.Bcl.Async can be installed for portable libraries targeting .NET 4.0/4.5, Windows Store apps, Silverlight 4/5, and Windows Phone 7.5/8.0 回答2: As a heads up, we've

问题 I am wondering why there is no .ToShortDateString in the .NET Portable Class Library. I have 2 projects (Silverlight, and regular .NET Class Library) that use the same code, and the code involves calling .ToShortDateString() on a DateTime object. In order to reuse the same code instead of copying it in 2 places, I created a portable class library so it can be imported by both Silverlight and .NET Class Library. Unfortunately, it doesn't seem like .ToShortDateString() is available when using

问题 I am writing a ConfigManager class using Portable Class Libraries.
