我有一个使用Lightswitch开发的简单应用程序。 所有文件都是在Lightswitch中创建的。 所有工作正常，直到今天下午，尝试构建时会弹出此错误。 该计划没有变更
。 我只是想做一个新的构建（重新构建）而且我得到了这个。

I have a simple application under development with Lightswitch.  All of the files were being created from within Lightswitch.  All was working fine until this afternoon, and this error popped up when attempting a build.  There were no changes made to the program.  I just wanted to do a fresh build ( re-build ) and I got this.

这在几周之前发生过一次，我从来没有找到答案。 我刚刚开始这个项目。

This happened once before several weeks ago and I never did find an answer.  I just started the project all over.

我在这台电脑上使用SQL Express 2008.

I am using SQL Express 2008 on this computer.
