dlls not found for builds


I've come up with an issue when building the tutorial Holograms 100 project. As instructed, I imported the project from Unity to VS, modified the appxmanifest file, changed the target, and then run it with Start without Debugging, which gives me errors in attached image.

As you see the issue is that somehow the dll files is not generated at the right place. For example as I look into the path for the first error, the dll file is actually in a Unprocessed file under Debug. And every time I rebuild it the dll will just automatically reappear in that file. I am guessing VS created this Unprocessed thing and put everything not recognized into it. but why? Is it because VS is not configured correctly? Interesting thing is that for the third error (in Assembly-CSharp), there is no such Unprocessed file under Debug, and still no dll file found. I am totally unsure why this is happening.

I tried searching online and unchecking+rechecking boxes under build option in configuration does not work for me. I believe the last two errors are also relevant to this issue. Any ideas? Thanks for any suggestions.

  • It looks like you're trying to build for ARM. HoloLens is an x86 device. Change the dropdowns on the top to "Release" and "x86".
  • In addition to changing the build type to x86, you might try right clicking on the solution and choosing "rebuild all". I had that same issue you showed and it helped to rebuild the entire solution prior to trying to deploy to the hololens. YMMV.

    Your build path length has exceeded a known bug length .Total length is about 40 characters for example c:\unity\holo210\
    The shorter the better or serialweaver.exe will fail
  • @Jimbohalo10 I created another new project directly under C:\ and now the path is C:\holo100. But it seems that serialweaver is still crashing, and error msgs are similar. I am not is this the right way to shorten the path length you mentioned since it doesn't work.

    I've attached new error msgs and the info in output window. Pretty sure there is length issue based on the index out of range exception, but unsure how to handle it. Do you see other way out of this?

    @johnp I cannot see why this is happening, but similar problems in other thread here

    Could you try building the code given in my Tutorial: Debugging with Holograms 211 with update code library

    This is very detailed and would avoid my of the pitfalls that earlier code has given HoloLens developers. This would test your development environment and make troubleshooting easier.
