如何在 Visual Studio 中使用类库的输出类型调试项目？

Question

我遇到了需要在类库项目的方法中调试的问题？但是我收到一个项目错误说“无法直接启动具有类库输出类型的项目”？ 有没有办法解决这个问题？我的项目是一个用户控件。

Answer 1

通常我会创建一个单独的单元测试类库项目，然后在您最喜欢的单元测试运行器中启动，并以这种方式进行调试。

或者，开始调试实际使用您的类库的任何应用程序，练习将遇到您想要设置的任何断点的功能，然后从那里继续。

Answer 2

设置第二个小项目来使用该库。

Answer 3

将 Visual Studio 调试器附加到运行二进制文件的进程。

Answer 4

我同意 Jon Skeet 的观点。 TDD（测试驱动开发）是面向服务或业务逻辑类的最佳方式。

它允许您启动 GUI 的一小部分并对其进行测试，而无需加载整个应用程序。
