.NET4.0中奇怪的StructureMap行为

我有一段代码可以用四种方式运行

1. 调试内置-在调试器-工作正常

2. 调试生成-外部调试器-失败

4. 发布生成-在调试器外部-失败。

错误代码在所有情况下都是202—与无参数构造函数有关,调用堆栈位于底部。

我无法使用debug构建源代码,因为我使用的是.NET4.0,而且似乎没有安装.NET2.0SDK来构建它。

我开始没有主意了。。。。

例外情况:

Test method DataLoaders.Integration.ContactMappingTests.EntityContactMappingTest threw exception: 
StructureMap.StructureMapException: StructureMap Exception Code:  202
No Default Instance defined for PluginFamily System.Uri, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089

调用堆栈:
