推荐答案

无法从程序集"Microsoft.Expression"中加载类型"Microsoft.Expression.DesignModel.Core.ISharedInstanceBuilder" .DesignModel，Version = 4.0.0.0
参考: VS 2010 XAML设计视图加载始终因类型加载而失败例外 [
2.在刚刚启动的命令提示符下，运行"gacutil/l Microsoft.Expression.DesignModel"以查看该程序集是否在GAC中.
3.如果是这样，请运行"gacutil/u Microsoft.Expression.DesignModel"以将其从GAC中删除-不应存在.

4.现在，再次尝试运行Visual Studio，然后尝试显示问题的操作-现在应该可以了.

Could not load type ''Microsoft.Expression.DesignModel.Core.ISharedInstanceBuilder'' from assembly ''Microsoft.Expression.DesignModel, Version=4.0.0.0
Refer: VS 2010 XAML Design View Load always fail with a Type Load Exception[^]

It says:
Looking at this error, we suspect a bad copy of this assembly somehow got into the GAC and is supplanting Visual Studio''s version of the Microsoft.Expression.DesignModel assembly (the Visual Studio designer uses portions of Blend). You can prove this by attaching a debugger or using file monitor to check the path this assembly is being loaded from. It should be loaded from %programfiles%\microsoft visual studio 10.0\common7\ide\privateassemblies.

The copy of the assembly in PrivateAssemblies has the required interface and is required to make the Visual Studio designer work.

To remedy:

1. Quit all copies of Visual Studio, then fire up an elevated Visual Studio command prompt (you should see "Visual Studio Command Prompt (2010)" under the Visual Studio folder on your start menu - right click and run it as administrator assuming you''re on a Windows 7 or Windows Vista PC.

2. In the command prompt you just started, run "gacutil /l Microsoft.Expression.DesignModel" to see if the assembly is in the GAC

3. If it is, then run "gacutil /u Microsoft.Expression.DesignModel" to remove it from the GAC - it should NOT be there.

4. Now try running Visual Studio again and try the action that showed the problem - it should be OK now.
