VS2015 Breakpoint bind successful but after some rows failed to bind

In one file I can bind breakpoint up to certain position but not after some specific row.

For example I can bind within function first x rows, but trying to set breakpoint further I get "The breakpoint failed to bind". If i step through rows, I can do it only up to the point I can successfully bind.

This is after I merged assembly with ILMerge. Before merge it was working OK. The symbols are loaded successfully (but after I manually right click on module and click Load Symbols). Symbols get loaded that ilmerge has provided.

Using reflection I could verify the class I ILMerged is available (Newtonsoft JSON)

For full picture: Assembly is used within Dynamics CRM and DLL is published to database, if that makes any difference. I am using Remote Debugger if that makes difference.

Where should I dig further? What could cause it to behave like that?

A picture may be worth thousand words

Solution

  • Looks like it has something to do with the 3rd party ILMerged assembly.

    For debugging to work, I deployed 3rd party assembly to GAC and didn't merge until I want to build a release version for deployment for which debugging isn't necessary.
