What to do now, this time??
I hate VS and this symbolic gibberish that never seem to have same solution (if it once was logic) twice. The screendump below says what it says.
As soon as I F5/Start the web project, the breakpoint going yellow. This ONLY affect the aspx.cs file that being changed. The other aspx.cs files can have breakpoints.
When I do rebuild/build all DLL and PDB files are created just fine. They have same compile time and are in same directory. Module-Windows i VS says the symbols are loaded perfectly. Well, yeah, try bite me!
I can tell, all symbolic is working just fine, until I was about doing changes inside those aspx.cs files (which was some time ago since last time). If I reset back the file, the breakpoint are working. If I try to make changes in another file, the problem appears there.
It simply appears like that the symbolic file generator don’t understand changes maded in aspx.cs files..

I’ve found a good hint (see my comment higher in this thread).
The WEBAPP have, as seen above, an _dll path.
This _dll path are there because this project has dll files shared with other projects. This means save space and don’t have copies of same files for several projects.
Though,
This raise problems beause the webapp still are output/copy files to it’s own sub bin/ directory. And even worse, not ALL needed dlls, which make error when the running web project (due to missing xxWeb.dll, which copies to _dll bin).
Accepting the fact to use standard bin/ fixed the problem this time. Why? The answer on that will not be in this thread, sorry. Someone with an idea would course make a comment here. In general, this isn’t a drawback because the webb project binaries should be at the end of reference tree..
