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.

Acquisition method of CameraResolution in the research mode


I occurred a problem.
And It hasn't resolve yet :'(

I wrote the following code.

        cameraResolution = 
           .OrderByDescending((res) => res.width * res.height).First();

and in the research mode

InvalidOperationException: Sequence contains no elements
   at System.Linq.Enumerable.First[TSource](IEnumerable`1 source)

Will occur.
I can obtain cameraResolution correctly by releasing the research mode.

I think other acquisition method in the research mode.

Does anyone know the solution?


  • Hi @ShingoMORIO36 ,
    If you don't mind, could you answer a few question, so I could understand your scenario better please ?
    1. Is this App a Unity App or UWP ?
    2. Have you enabled Research Mode ?
    3. Is your end goal to access the PhotoVideo camera or Research Mode cameras ?
