Expression Blend为什么不呈现我的用户控件?它只显示XAML [英] Why isn't Expression Blend rendering my User Control? It's only showing XAML

问题描述

我在Expression Blend 3的VS2008解决方案中打开有效的XAML，并且仅在尝试打开单个XAML文件时显示XAML.我的解决方案/项目全部正确构建并运行.

I'm opening valid XAML within my VS2008 solution in Expression Blend 3 and it is only showing XAML when I try to open individual XAML files. My solution/projects all build and run correctly.

当我进入视图-> 活动文档视图时， 设计视图 ， 和 XAML View 选项都显示为灰色...这没什么意义.

When I go to View -> Active Document View the Design View, Split View and XAML View options are all grayed out... which doesn't make much sense.

我不是一个Blend用户，但以前从未发生过这种情况，而我在解决该问题方面空无一物.有什么想法吗?

I'm not much of a Blend user, but this has never happened before, and I'm coming up blank for how to fix it. Any ideas?

推荐答案

您是如何创建项目的?您是否在Visual Studio中使用了类库"模板?

How did you create your project ? Did you use the "Class library" templates in Visual Studio ?

我记得我有一个类似的问题.您可以创建一个新的WPF项目，并将CSPROJ与在Blend中不起作用的项目进行比较.您应该能够看到差异并在CSPROJ中添加缺少的行.

I remember I had a similar problem. You can create a new WPF project and compare the CSPROJ with the one not working in Blend. You should be able to see the differences and add the missing lines in your CSPROJ.
