We have decided to phase out the Mixed Reality Forums over the next few months in favor of other ways to connect with us.
The first way we want to connect with you is our mixed reality developer program, which you can sign up for at https://aka.ms/IWantMR.
The plan between now and the beginning of May is to clean up old, unanswered questions that are no longer relevant. The forums will remain open and usable.
On May 1st we will be locking the forums to new posts and replies. They will remain available for another three months for the purposes of searching them, and then they will be closed altogether on August 1st.
So, where does that leave our awesome community to ask questions? Well, there are a few places we want to engage with you. For technical questions, please use Stack Overflow, and tag your questions using either hololens or windows-mixed-reality. If you want to join in discussions, please do so in the HoloDevelopers Slack, which you can join by going to https://aka.ms/holodevelopers. And always feel free to hit us up on Twitter @MxdRealityDev.
Holographic Emulator hangs before Unity splash screen
I am running Visual Studio 2015 update 3, Unity 5.6.3f1, Holographic Emulator 10.0.14393.1358 and Windows 10 SDK 10.0.14393.798. I am just working through a Pluralsight course for HoloLens Development Fundamentals and I keep running into this issue when I deploy my app to the HoloLens emulator.
Whether I run without debugging or run with debugging and do not set any breakpoints, I see the start menu bloom just fine and then it clears and at the point where the Unity splash screen is supposed to display, I just get the small white cursor in the middle of the screen and nothing else ever happens.
However, If I set a breakpoint in the app.cs constructor and then step through the code, I can then see the splash screen appear and the app runs once I step through the Main method and the CoreApplication.Run(App) method call.
When looking at the ouotput log, when the program hangs, it stops at the point shown below.

however, when the program runs correctly as a result of me setting a breakpoint and stepping through the code, the following lines appear after in the output window

I found a post on redditt r/HoloLens that talked about "Go into player settings -> other settings -> Color Space and swap it to Gamma rather than Linear", but my setting is already on Gamma so that doesn't seem to apply.
