System.ComponentModel.DescriptionAttribute in portable class library

阅读更多关于 System.ComponentModel.DescriptionAttribute in portable class library

问题 I am using the Description attribute in my enums to provide a user friendly name to an enum field. e.g. public enum InstallationType { [Description("Forward of Bulk Head")] FORWARD = 0, [Description("Rear of Bulk Head")] REAR = 1, [Description("Roof Mounted")] ROOF = 2, } And accessing this is easy with a nice helper method: public static string GetDescriptionFromEnumValue(Enum value) { DescriptionAttribute attribute = value.GetType() .GetField(value.ToString()) .GetCustomAttributes(typeof

Modify request headers per request C# HttpClient PCL

阅读更多关于 Modify request headers per request C# HttpClient PCL

问题 I'm currently using the System.Net.Http.HttpClient for cross platform support. I read that it is not a good practice to instantiate a HttpClient object for each request and that you should reuse it whenever possible. Now I have a problem while writing a client library for a service. Some API calls need to have a specific header, some MUST not include this specific header. It seems that I can only manipulate the "DefaultRequestHeaders" which will be send with each request. Is there an option

MonoDevelop: is it possible to switch PCL's compiler?

阅读更多关于 MonoDevelop: is it possible to switch PCL's compiler?

We are starting a cross-platform project to be deployed to Android and iOS. Obviously, a lot of code is to be shared between the two, and some of the code relies heavily on the .NET framework items, like sqlite-net library does. The best way (afaik) to share the code between 2 projects is to use a PCL – this way it is possible to reference the project with shared code from both iOS and Android projects in a solution and have everything re-compiled and linked in a nice manner. However, a PCL created in MonoDevelop is compiled with gmcs compiler and some of external dependencies fail to be built

Is there an alternative to AppDomain.GetAssemblies on portable library?

阅读更多关于 Is there an alternative to AppDomain.GetAssemblies on portable library?

I'm looking for a way to get the current app's assemblies inside a portable library project. In classic library project, the code line below do the job: var assemblies = System.AppDomain.CurrentDomain.GetAssemblies(); But seems that System.AppDomain is not available to portable library. Does anyone know a way to get the current domain assemblies on portable library? You can use platform hooks: In your portable library: using System.Collections.Generic; namespace PCL { public interface IAppDomain { IList<IAssembly> GetAssemblies(); } public interface IAssembly { string GetName(); } public class

Update UI thread from portable class library

阅读更多关于 Update UI thread from portable class library

I have an MVVM Cross application running on Windows Phone 8 which I recently ported across to using Portable Class Libraries. The view models are within the portable class library and one of them exposes a property which enables and disables a PerformanceProgressBar from the Silverlight for WP toolkit through data binding. When the user presses a button a RelayCommand kicks off a background process which sets the property to true which should enable the progress bar and does the background processing. Before I ported it to a PCL I was able to invoke the change from the UI thread to ensure the

Windows Phone development and Unit Testing

问题 I'm looking to start a project targeting Windows Phone, but I'm slightly put off by the lack of unit testing support[1]. I'm used to using NUnit/ XUnit for most of my testing needs, with something like NSubstitute for mocking. Near as I can tell, you can't use these frameworks for Windows Phone projects... Given some investigation, I was wondering if the following scenario would work: Use Visual Studio 2012 Create a Portable Class Library project(s) for the View Models and other logic Create

问题 recently we started to work on a new project which includes clients for Windows 8 Metro, Windows Phone and Desktop application. it was decided to use MVVM pattern as main Architecture because sharing ViewModels between projects is much more acceptable solution for us. we decided to use portable class library for this purpose, but the problem is that after downloading and installing SQLite for windows runtime from Visualstudio 2012 extension gallery when we try to add reference to appropriate

Why doesn't String class implement IEnumerable<char> in portable library?

阅读更多关于 Why doesn't String class implement IEnumerable in portable library?

I've created a PCL project that targets .NET Framework 4 and Silverlight 5 (I use an extension for Visual Studio 2010, not portable project template from Visual Studio 2012, if that matters). I am trying to reverse a string using System.Linq.Enumerable.Reverse<TSource>() extension method, but it doesn't work because compiler thinks that System.String doesn't implement IEnumerable<char> . Hans Passant The Portable Class Libraries must restrict itself to the classes and methods that are available on all the target platforms it promises to support. The biggest trouble-maker here is WinRT, the CLR
