How to use GetFileFromApplicationUriAsync

Adam

Hello all,

I am trying to load a .cmo file located in my Assets folder and for the life of me I cannot get it to work.

Here is a code snippet

    auto loadModelDataTask = task<void>( [this, meshDataVector]()
    {
      auto storageTask = create_task( StorageFile::GetFileFromApplicationUriAsync( ref new Windows::Foundation::Uri( "ms-appx:///Assets/model.cmo" ) ) );
      auto storageFile = storageTask.get();
      ...
     }

The exception I get is "WinRT information: The system cannot find the file specified."

What am I doing wrong?

So, after some pure-unadulterated-luck, I noticed in the build output that the .cmo file was not listed in the:

GetPackagingOutputs: ... 2> NewProject: NewProject.ContentFilesProjectOutputGroup : C:\d\AR\HoloLens\NewProject\NewProject\Assets\model.cmo -> Assets\model.cmo ...

The above line was not in the list of all the other assets!

This led me to believe that the file was not flagged as "Should be deployed as an asset." I brought up the item properties and changed the entry's General property Item Type from Does not participate in build to Media.

Edit: You do not need to assign it a type. You can just set the Content field to Yes

Once that was set, the file is included in the deployment, and the call to load the file from uri works as expected.
