Hello everyone.

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.

What are the requirements to build apps on hololens successfully with IL2CPP as a scripting backend?

edited October 2018 in General

I switched from .NET to IL2CPP due to .NET being depricated and so on.
Sadly i can't deploy on device in Visual Studio. There is always a Pop Up with "These Projects are outdated." Why are my new Projects outdated?! And how can I resolve this issue? If i create them new due to the pop up asking for it, i always get an error about "standard collector bridge".

    I've done successful builds and deploys using the following settings:
    Device: HoloLens (Any Device also has worked for HoloLens)
    Build Type: D3D
    SDK: Latest(10.17763.0)
    Build and Run: USB Device (this appeared when I installed unity with UWP support)
    Scripting API: .NET 4.x equivalent
    Backend: IL2CPP

    After you build the solution will have a device option in the start debugger I believe it defaults to Remote Device but switch it to Device, connect the HoloLens with USB, select x86 as Architecture

    things to keep in mind make sure Win10 Holographic is updated to the same SDK you are using, and it may ask you to request a pin in 1st deploy you can get the pin in the HoloLens' Developer Settings
