wix c# app doesn't launch after installing

Question

I have already successfully generated and successfully installed my C # WPF application with Wix. The application includes Crystal report dll and some other dll like Zen Barecode. After an nth attempt to modify the main project, the MSI is able to install itself but by launching the application either from the shortcuts or the executable directly, it does not start.

Here is my wix product.wxs

Answer 1

After closely following Stein's guidelines on binary debugging (which took a little time to complete since it's my first time), I attached a box message to the execution sequence of my application (precisely in the constructor of the App class of my application WPF), then a break point directly on the instruction that follows the message box. I then generated the application, recreated the msi and then installed the msi. After launching the executable from the desktop shortcut, the message box appeared. I entered my source code before clicking on the OK button of the message box, I attached the process of my application (Debug -> Attach to process). The validation of the message box returned to me on Visual Studio, I was able to follow step by step the portion of the code until falling back on the small flat.
