    We need to load content dynamically using AssetBundles.

    I'm doing this..

    Code (CSharp):
    1.  
    2. using UnityEditor;
    3.  
    4. public class CreateAssetBundles {
    5.  
    6.     [MenuItem("Assets/Build AssetBundles")]
    7.     static void BuildAllAssetBundles()
    8.     {
    9.         BuildPipeline.BuildAssetBundles("Assets/AssetBundles", BuildAssetBundleOptions.None, BuildTarget.WSAPlayer);
    10.     }
    11. }
    and getting: Error building Player because scripts have compile errors in the editor

    Is this script in your project's Assets\Editor folder? See https://docs.unity3d.com/Manual/SpecialFolders.html.

    If you still get any errors, information on the errors you get would be useful. "Error building Player because scripts have compiler errors" is a generic error when building if you had other errors, that error alone doesn't really tell us anything.

    I started over. Now I'm using the AssetBundleManager found here: https://www.assetstore.unity3d.com/en/#!/content/45836

    It works fine on a new project with PC platform .

    When I switch to Windows Store for HoloLens platform, I cannot build assets anymore and get the following error:

    ArgumentNullException: Argument cannot be null.
    Parameter name: path2
    System.IO.Path.Combine (System.String path1, System.String path2) (at /Users/builduser/buildslave/mono/build/mcs/class/corlib/System.IO/Path.cs:115)
    AssetBundles.BuildScript.BuildAssetBundles () (at Assets/AssetBundleManager/Editor/BuildScript.cs:19)
    AssetBundles.AssetBundlesMenuItems.BuildAssetBundles () (at Assets/AssetBundleManager/Editor/AssetbundlesMenuItems.cs:27)


    I think the new Windows Store Platform build does not yet support the AssetBundleManager. Can you confirm?

    Asset bundles work on Windows Store just fine. I don't know about that plugin, though. The error is pretty straightforward though: that script is passing null into System.IO.Path.Combine.

    It's missing the build platform. So I added the WSAPlayer for Windows Store. When I attempted to build it created the path but I'm still getting errors. It's a very vague error now :
    Error building Player because scripts have compile errors in the editor.

    It's definitely specific to Windows Store, if I switch to another platform it works fine.

    What would you recommend using to get going quickly with AssetBundle Loading and Building in my HoloLens project?

    I went real basic and now have BuildAllAssetBundles() working just fine in my HoloLens Unity 5.50f3 project!

    I also want to know how to get assetbundles working in build, it crashes anytime we include them...

    I seem to be getting the same error as @spinteractive and would like to find a fix:

    ArgumentNullException: Argument cannot be null.
    Parameter name: path2
    System.IO.Path.Combine (System.String path1, System.String path2) (at /Users/builduser/buildslave/mono/build/mcs/class/corlib/System.IO/Path.cs:115)
    AssetBundles.BuildScript.BuildAssetBundles () (at Assets/AssetBundleManager/Editor/BuildScript.cs:19)
    AssetBundles.AssetBundlesMenuItems.BuildAssetBundles () (at Assets/AssetBundleManager/Editor/AssetbundlesMenuItems.cs:27)

    Looks like an exception in your code?
