调试报The source file is different from when the module was built error解决办法！

之前有个项目,一个Solution里面有几个consoleapp,一个website,调试没发现有任何错误,但是今天建立一个新的项目，类似之前的，发现每次改完代码，DLL引用的地址并非我references的地址，Google一下，老外给了各种建议：

I got this issue running a console app where the source that was different was the source that had the entry-point (static void Main). Deleting the bin and obj directories and doing a full rebuild seemed to correct this, but every time I made a code change, it would go out-of-date again.

The reason I found for this was:

I had checked "Only build startup projects and dependencies on Run" (Tools -> Options -> Projects and Solutions -> Build and Run)
In Configuration Manager, my start-up project didn't have "Build" checked

然而我按照他的步骤，却还是报module was built error！

当然准备crazy的时候，发现在每个项目右键中有个“build dependencies”里面有“project dependencies”引用需要的consoleapp就解决问题了。
