[map 3d开发实战系列] map resource explorer 背景介绍--kick off

[map 3d开发实战系列] map resource explorer 之二-- 运行和调试

[map 3d开发实战系列] map resource explorer 之三-- 添加autocad风格的palette界面

如果你已经随着我们前面的文章开始创建基于wpf技术的map 3d自定义界面的话，你可能会遇到一个比较棘手的问题，就是在visual studio 2008中的wpf编辑器中，可视化界面总是显示错误，从而不能想winform界面设计一样拖控件进去。更麻烦的是两xaml编辑器的智能提示都没有了，这对我这样的wpf菜鸟来说真是要命啊！

每次在visual studio 2008中打开xaml文件，总是显示下面的错误信息：

an unhandled exception has occured.

a badimageformatexception has been thrown while parsing the signature. this is likely due to lack of a generic context. ensure generictypearguments and genericmethodarguments are provided and contain enough context.

这其实是map 3d 2011的一个bug。前面的文章中介绍了，我们要开发map 3d 应用程序，需要添加下列的map 3d相关引用：

map 3d相关程序集：

autodesk.map.platform.dll

autodesk.map.platform.core.dll

autodesk.map.platform.utils.dll;

autodesk.gis.map.shared.dll;

osgeo.mapguide.foundation.dll

osgeo.maoguide.platformbase.dll

但引用的上面的map 3d相关程序集，就会造成visual studio 的wpf编辑器工作不正常。当然你可以使用blend，xamlpad等其他工具来编辑xaml界面，但对于我们简单的界面设计来说，blend有点大材小用，而且学习这个软件也得花不少时间。

解决的办法就是在设计界面是，暂时把上面的map 3d相关程序集的引用移除，这样wpf界面编辑器就可以正常工作了。编辑好了界面，需要编译运行时，再重新把这些程序集的引用加进来就行了。visual studio引用对话框的recent选项卡可以快速的帮我找到最近用过的程序集，还是很方便的。

好了，先到这里，现在你可以开始设计你的基于map 3d应用程序wpf界面了。
