UWP JS Target version 15063 and 16299 Visual Studio Debugging doesnt work

Question

I'm working on UWP + JS project and the current target version is Windows 10 14393. If I change the the target version to higher like 15063 or 16299, The debugger is never hit on the managed code. The Managed code part is done as Windows runtime library project which is references from the JS UI project.

The app code is actully working out the logic and inserting the entries to DB and also runs the Background jobs such that the Web services called from there are actually hit.

I used to get the debugger hit with target version being 14393. I created the project with VS2015 and now using VS2017. Is there something I'm missing.

I got an error in event viewer too.
