.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\

4/2019: found an alternative, with VS 2017 installer you can right click on the right hand side components and hand pick the various .NET components you want to install. what a mess!

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.

Update: 3/1/19:

Had same issue and found above solution didn't resolve the issue but copying the Packages directory one level down did resolve the issue. Thinking one of the projects got fixed and others did not....sigh.

Summary from extremetech re:Sebestian Duserwald's description:

[I]n ray tracing a ray is sent out from the virtual camera into the scene and traced until it intersects with a solid body. At this point a ray is cast to each of the light sources in the scene to calculate illumination and surface shading is calculated for the intersection point. If the surface is transparent the ray is sent out further into the scene, possibly at an angle to simulate refraction. If the surface is reflective a ray is sent out at an angle away from the object…
[A] path tracer is like a ray tracer on steroids. Instead of sending out one ray it sends out tens, hundreds or even thousands of rays for each pixel to be rendered. When it hits a surface it doesn’t trace a path to every light source, instead it bounces the ray off the surface and keeps bouncing it until it hits a light source or exhausts some bounce limit. It then calculates the amount of light transferred all the way to the pixel, including any colour information gathered from surfaces along the way. It then averages out the values calculated from all the paths that were traced into the scene to get the final pixel colour value.
Path tracing can be used for effects that ray tracing still has to fake, according to Dusterwald
