问题 I'm trying to make a range slider for metro style app, because it's not available. I'm trying to leverage an existing silverlight range slider, but it's not going to well. I changed the code a bit, but now it just shows the slider and I can't move the thumbs. Here is the xaml code: <UserControl x:Class="Mecoms_Mobile_App.RangeSlider" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" > <Grid x:Name="LayoutRoot" Background=

问题 I have a MVC 3 application that targets .net 4.0 It has a dozen or so projects also targeting .net 4.0 I have created a new project for the solution targeting .net 4.5 that uses reflection (there are a couple of nice bits of functionality in 4.5 that I want to use).

问题 I've trying to write a extendable metro app using MEF. I got it working with a local extension (inside of the current assembly). Now I want to load a external dll. The DirectoryCatalog seems to be not present in .net 4.5. So I tried to use ApplicationCatalog but I got the following error while calling SatisfyImportsOnce : Assembly.LoadFrom is not supported in AppX. . Here's me code: var catalog = new AssemblyCatalog(GetType().GetTypeInfo().Assembly); ApplicationCatalog catApp = new

问题 I have a WebAPI, and I need to secure an Angular 4.x app so I though I could use JWT. I'm trying to figure out what's the bare minimum (no OAuth?) to achieve it using Microsoft's OWIN Katana 3.x packages. How can it be done? 回答1: The following doesn't work (Microsoft's/System parts entangled in a breaking way). But it's the closest I could get to something looking almost simple. using System.IdentityModel.Tokens.Jwt; using System.Security.Claims; using System.Security.Cryptography; using

问题 At first, I thought if I added an implementation of IDispatchMessageInspector, that perhaps this would intercept the message size before any checking on the limit is done.

Now I am curious if there is a way in which I can capture such an exception on the server level and return a response to the client. Would the an implementation of IErrorHandler as a ServiceBehavior do the
