Debugging C# application - Visual Studio

Question

I am trying to learn C# and have followed the instructions in this tutorial

I have created a project, added the controls to the design surface and added code to the button click event. When I get to the part which asks me to test the application, I click "start debugging" and I get an error message saying

There were build errors, would you like to continue and run the last successful build?

If I click no, nothing happens. If I click yes I get another error saying:

Visual Studio cannot start debugging because the debug target 'C:\\Users\\hp\\source\\repos\\HelloWPFApp\\HelloWPFApp\\bin\\Debug\\HelloWPFApp.exe' is missing.

As a complete beginner I have no idea why this exe file is missing or how to fix it. Could someone point me in the right direction at all?

Answer 1

It's possible that your code has never compiled. Press Ctrl-Shift-B and try again (or look in the Build menu).

Answer 2

我现在没有VS，为什么不重建（或全部重建）您的项目，如果重建成功，则检查该文件夹中是否存在可执行文件，还检查发布文件夹（如果存在），然后更改重建据我记得，您会在工具栏上看到一个下拉菜单，

Answer 3

First: You should clean the project than Build project again.

Second: Run project by pressing F5

Executable file you can find in bin/Debug folder in your root of project.
