MBP stability with 3 external displays

Not totally root caused, but making this note to myself: When attaching a 3rd external 4k display I was able to get it to work but came home from dinner after entire rebuild and hours (not days) of stability to a BSOD. Rebooting and it seems that 3rd external display seems to wreak havoc. Went back to 2 external and using the laptop display for still 3 total. Recall the reason for my entire rebuild was when pulling out the same 4k display adapter that cause me to lose audio and Skype abilities....just deciding to stay away from a 3rd external display for now. Not worth the issues ATM.

Maybe total video bandwidth issues? Working past thermal limits where there wasn't adequate testing of drivers?  Cheap external 4k display? Cheap external adapters from USB-C to DP and/or HDMI (both seemed to create problems).

no time to root cause, solved the problem short term and moved on.

update: 2/11/19, stable after one week by going to the 2 external+laptop display vs. the 3 external.

.NET 'the reference assemblies for framework ".NETFramework, Version=4.5" were not found

Windows thoroughly confused about this issue. 

Fix was to go to a machine with the assemblies and just copy the 100MB over.

c:\program files(x86)\reference assemblie\microsoft framework\.NETFramework\v4.5\

remote debugging reminders

When i try to get remote debug working on a new system, I usually try with a completely empty very simple Hello World to make sure all the shares are mounted, permissions are correct, etc.

Recently had a simple sample not work right and had to iron out some things i had forgotten:

Reminder if you've only installed 64bit remote debug tools you need to build 64bit binary for remote deployment.

Also, to get remote access to mount a shared drive you have to enable sharing and do a trial run with Remote Desktop both directions just to make sure the systems can see each other.

Randomly had a 'hello world' build from one of the Visual Studio wizards refuse to let me set a breakpoint. Creating an empty project (no files, no .pch, etc.) I got things to work.

building miniengine issue

Modify Nuget.Config in the MiniEngine directory from:
    add key="repositoryPath" value="..\Packages"
    add key="repositoryPath" value=".\Packages"

This matches previously functional versions of MiniEngine.  Might just be related to some internal changes that are not yet completely checked in.
