问题描述
我是在创造一些标记扩展工作，并开始得到VS行为很怪异。我已提取并在分开溶液精确定位的问题。问题是，VS不能创建XAML中的CLR对象。
I was working on creating some markup extensions and started to get very weird VS behaviours. I have extracted and pinpointed the issue in the separate solution. Problem is that VS can't create a CLR object in XAML.
下面是：
查看：
<Window x:Class="WpfApplication4.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:wpfApplication4="clr-namespace:WpfApplication4">
<Window.Resources>
<wpfApplication4:Dog x:Key="doggy" />
</Window.Resources>
<Grid />
</Window>
后面的 code：
using System.Windows;
namespace WpfApplication4
{
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}
}
}
狗类：
namespace WpfApplication4
{
public class Dog
{
}
}
的App.xaml（在App.Xaml.cs没有code）：
<Application x:Class="WpfApplication4.App"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
StartupUri="MainWindow.xaml">
<Application.Resources>
</Application.Resources>
</Application>
例外我得到：
Error 1 The name "Dog" does not exist in the namespace "clr-namespace:WpfApplication4". \\hopr1\folders$\vxk\Documents\Visual Studio 2012\Projects\WpfApplication4\MainWindow.xaml 6 9 WpfApplication4
我能够运行的解决方案，但设计师失败，无效的标记错误
任何想法？
I am able to run solution, but designer fails with "Invalid Markup" errorAny ideas?
修改
我运行VS 2012更新2
在VS 2012 Update 1中相同的解决方案的工作
I am running VS 2012 Update 2The same solution work in VS 2012 Update 1
推荐答案
您解决方案是在网络共享上运行。 .NET（和Visual Studio）的应用程序可以在网络共享上运行时，碰上许可/准入问题。
Your solution is running on a network share. .Net (and Visual Studio) applications can run into permission / access issues when running on a network share.
复制解决方案到本地驱动器（完全信任），你应该罚款。
Copy your solution to a local drive (with full trust) and you should be fine.
有可能得到一个网络驱动器以完全信任的工作 - 你可以找到计算器等地为这个答案 - 但我的经验我一直运行到障碍物当我这样做，所以要尽量避免它，除非它是绝对手边的问题是至关重要的。
It is possible to get a network drive working with full trust - you can find answers for this on StackOverflow and other places - but in my experience I keep running into obstacles when I do this, so try to avoid it unless it's absolutely critical to the problem at hand.
例如。这个问题给出了有关如何执行此操作的说明：
E.g. this question gives instructions about how to do this:
Give将FullTrust到UNC共享为Visual Studio 2012和.NET 4.0
我只曾与VS2010使（如链接所示）则可能有更好的喜悦2012试过这个。
I've only ever tried this with VS2010 so (as indicated in the link) you might have better joy with 2012.
