portable-class-library

问题 I'm building some code with these portable class libraries at present. I'm looking to target full .Net, WinRT Metro, Windows Phone, ... and then MonoTouch and MonoDroid. My experiments today show this can work - http://slodge.blogspot.co.uk/2012/04/experiments-with-portable-class.html However, I have hit a fairly significant problem - MonoTouch and MonoDroid currently support these libraries in that you can consume PCLs as binary assemblies, but they don't allow linking between project files

问题 So I'm writing a portable class library that targets .NET 4.5, Windows 8 and Windows Phone 8. I'm trying to read from a text file that is part of the project as build content. I see that StreamReader is available in PCL's but I can't seem to find out how to get the stream from a file, given a file path. If anyone could point me to the right structures I'd appreciate it. Also if you could give direction for XML files, too. I'm only reading text files right now, but I'm going to be working in

问题 I'm developing a Xamarin Forms mobile app, which has a page containing a SearchBar, a ListView, and Map control. The list view contains a list of addresses, which are reflected as pins on the map.

Does anyone know how I can do this in the XAML? <Entry Text="{Binding Code}" Placeholder="Code" /> 回答1: Forms supports a KeyboardFlags.Suggestion enum which I assume is intended to control this behavior, but it doesn't appear to be very well documented. 回答2: Custom Keyboard instances can be created in XAML using the x:FactoryMethod attribute

问题 I am working on extending number of supported platforms for my app, it used to support .NET4/Windows Store/Windows Phone, but I hope to also cover Mono for Android and iOS. I've put all business logic, models and view models to portable class libraries (PCL) but it's a big dilemma what subset of platforms I should target. Each combination causes something to fail. Here are the results for 4 platforms that I might use: Profile 78 (NET45+WP8+Store): no problem with TPL,await/async and support

问题 In Xamarin client app, I want to access Azure Files using SAS token with Portable Class Library . It seems I can not do it using latest WindowAzure.Storage nuget package as it may only works with Blob, Table,... and it requires lots of dependencies. Is there anyway to accomplish this? 回答1: I ended up with using Azure File Storage REST API.
