工作流,这一周都在练习,WF的出现的确让工作流程显示得更加方便和明朗,

　　今天的日志,也没有特别要写方法和实例,这一周都在看实例,其中有个非常不解的地方,就是为什么老是提示 "启动失败(正在重启中)",和例子一模一样的样,问题出在哪里,我一行一行的对照都没有写错,就是DEBUG不到问题,查看日志提示:

　　这个问题就出现WSPBuilderProject1csproj 这个文件里面

　　最近两行改成这样就OK了

　　 <Import Project="$(MSBuildBinPath)\Microsoft.CSharp.targets" />
 　　<Import Project="$(MSBuildExtensionsPath)\Microsoft\Windows Workflow Foundation\v3.5\Workflow.Targets" />
