问题 I have a PCL that targets the following platforms: .NET Framework 4.5 Windows 8 Windows Phone 8.1 I need to add a reference to System.Runtime because I want to use another package that depends on it. From what I can see, version 4.0.0 appears to include the target platforms mentioned above. However, when I try installing it via NuGet, I get this stack trace: PM> Install-Package System.Runtime -Version 4.0.0 # ... Install failed. Rolling back... Package 'System.Runtime 4.0.0' does not exist in

问题 I wrote a PCL with custom objects in there, and then I create a GUI that handles the objects from the PCL... and I try to use PropertyGrid to edit the properties... I've already read that in order for the grid to know what to do with the object, I need to specify the EditorAttribute as well as providing a TypeConverter... but I don't think I could add those 2 in the PCL... Is there a way to handle this at the GUI level, like telling the PropertyGrid to use a specific type of Editor

问题 I have a Xamarin.Forms application, with this code in my App class (yes, this is just a sample to demonstrate the issue): public App() { BlobCache.ApplicationName = "MyApp"; BlobCache.EnsureInitialized(); // The root page of your application MainPage = GetMainPage(); } public object BlockingGetExternalUser() { return GetExternalUser().Result; } private async Task<object> GetExternalUser() { try { return await BlobCache.LocalMachine.GetObject<object>("user"); } catch (KeyNotFoundException) {

问题 I am using VS 2015 Pro. If I create a new project Class Library (portable) Targeting: NET Framework 4.0 Windows 8 all works fine. BUT when I add to the targeting: Windows Phone 8.1 the following two errors appear: There was a mismatch between the processor architecture of the project being built "MSIL" and the processor architecture of the reference "C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\mscorlib.dll", "x86". This mismatch may cause runtime failures. And the Linq not found: The type

问题 Background Hi all SO viewers. I am normally an Android developer, but now I'm developing a cross platform application targeting WPF and Android. That being said, there's practically no info on how to directly do what I want. So, I ended up finding a 3-part blog series that goes in depth on how to develop a Windows-based cross platform MVVM project. As long as I set the PCL to be compatible with Xamarin.Android, any code that doesn't throw an error SHOULD work once I get to the Android side of

问题 I have a NuGet package for a library that is currently implemented only for .NET 4. But I have ported library code to support various platforms (WinRT, SL5, WP8) so ideally I would like to package it as a portable class library (PCL) to simplify the maintenance. But the library is using LINQ to XML (XELements etc.) that requires targeting .NET 4.0.3 and installting .NET 4.0.3 on a client machine. So I have a dilemma regarding how to target plain .NET 4. If it was not about NuGet packages and
