*Description:

It seems that there's a maximum package length that plays nicely with attaching the debugger. However if you exceed that maximum, the debugger has problems attaching. For example:

A) Aaaaaa.Bbbbbbbb.Cccccccc.Dddddddd.Aaaaaa.Bbbbbbbb.Cccccccc (58 characters)

B) Aaaaaa.Bbbbbbbb.Cccccccc.Dddddddd.Aaaaaa.Bbbbbbbb.Cccccccccccccccccccccccccccccccccc (84 characters)

In the first scenario A) the debugger attaches and all is well.

In the second scenario B) the debugger fails to attach and actually crashes the application.

I tested this on both a physical device and emulator:

Physical Device - Nexus 5 - 6.0.1

VS Emulator - 6.0

*Reproduction:

[Ensure you are on a Windows PC with the latest stable as defined in *Version below]

1) File -> New Blank Android Application

2) Change the Package Name inside Android Manifest options to A) and B) to see the differences

*Expected Behavior:

The debugger should attach and be able to resolve a simple breakpoint with a long package name. Or it should be validated on the Windows side to enforce any Windows policies.

*Version Information:

Microsoft Visual Studio Professional 2015
Version 14.0.25421.03 Update 3
Microsoft .NET Framework
Version 4.6.01038
