    I created a test project to troubleshoot a build error. Using Unity 5.5.1f. I set up the project to build for Hololens and add Playmaker 1.8.3 which I have used on all of my Hololens projects without issue. Project builds and runs on Hololens.

    Add a simple ugui canvas with a button and slider. Add Playmakers ugui proxy add on and there was an issue compiling. There was a line of code with an issue and the Playmaker Forum Admin helped troubleshoot. The line of code and it's replacement are to follow;

    Code (CSharp):
    1.  }else if(valueType.BaseType == typeof(System.Enum) ){
    2.  
    3. Replaced with
    4.  
    5. }else if(value is System.Enum){
    After this edit the scene ran fine in the Unity editor and was able to build a solution vor VS.

    When building the solution in Visual Studio I get the following errors.

    Severity Code Description Project File Line Suppression State
    Error CS0006 Metadata file 'D:\Test\GeneratedProjects\UWP\Assembly-CSharp\bin\x86\Release\Assembly-CSharp.dll' could not be found


    Severity Code Description Project File Line Suppression State
    Error The command ""D:\Test\Unity\Tools\SerializationWeaver\SerializationWeaver.exe" "D:\Test\GeneratedProjects\UWP\Assembly-CSharp\bin\x86\Release\Unprocessed\Assembly-CSharp.dll" -pdb -verbose -unity-engine="D:\Test\uguitest\Unprocessed\UnityEngine.dll" -unity-networking="D:\Test\uguitest\Unprocessed\UnityEngine.Networking.dll" -additionalAssemblyPath="D:\Test\GeneratedProjects\UWP\Assembly-CSharp-firstpass\bin\x86\Release" "D:\Test\GeneratedProjects\UWP\Assembly-CSharp\obj\x86\Release\x86\Release"" exited with code 1.

    I have seen many threads with similar errors. Is there a set way to resolve this issue?

    Here is a link to the Playmaker Forums about this issue.

    Thanks,

    When this happens,in my experience deleting my sln files and re build from unity fixes it

    Can you paste the contents of the "output" window in Visual Studio when this happens?

    Here it is.

    Code (CSharp):
    1. Restoring NuGet packages...
    2. To prevent NuGet from restoring packages during build, open the Visual Studio Options dialog, click on the Package Manager node and uncheck 'Allow NuGet to download missing packages during build.'

    I have been in touch with the Playmaker Forum Admin, Jean, and he is trying to understand what is going on to fix if the issue is on that end. Any help would be greatly appreciated.

    If you build from Unity without "C# projects" option checked, does it work and not print this error? This is very likely to have nothing to do with playmaker and instead is an issue within Unity. Could we get a bug report on this?

    My Playmaker ugui test for Hololens without C# Projects selected builds in Visual Studio, installs and runs on the Hololens without issue. I thought having C# Project selected was a requirement for Hololens. Is it only necessary if further development in Visual Studio is needed?

    I'll submit a bug report shortly.

    Thank you for your assistance.

    It's not a requirement at all - it's just there for your convenience. Once you submit the bug report, could you tell me the 6 digit case number? Don't post the link, just the case number.

    Here is the case number.

    (Case 885997) Building Project for Hololens with C# Project selected will cause Visual Studio build to fail

    I will be doing a lot of testing of Playmaker with the uGui Proxy and Hololens over the next few days. I will report back on how it goes.

    Thank you very much for your assistance. :)

    Thanks. I received the bug report and looked into it. It's indeed a bug in our C# project generation - we generate the command line invocation for Serialization Weaver incorrectly. I fixed it and I'll be backporting the fix to oncoming patch releases.

    It should land in the first patch release of 5.6. I fixed a bit too late to put it into 5.6.

    What version of 5.6? I'm using 5.6.1f1 on my laptop and don't get the error at all, it all works perfectly.

    I had this issue in 5.6.1f1. It was fixed by removing using NUnit.Framework from one of my MonoBehavior scripts.

    Not the same error as the original poster, but I landed here where I googled this error.

    I did a search and found an Assembly-CSharp-firstpass.dll , its not where VStudio is looking for it, its in a "unprocessed" directory under where its looking for...
    So this error....
    Error CS0006 Metadata file 'C:\Users\user\Desktop\HoloMine\Keylogic_VirtualMine\app\GeneratedProjects\UWP\Assembly-CSharp-firstpass\bin\x86\Release\Assembly-CSharp-firstpass.dll' could not be found

    The dll is in
    'C:\Users\user\Desktop\HoloMine\Keylogic_VirtualMine\app\GeneratedProjects\UWP\Assembly-CSharp-firstpass\bin\x86\Release\Unprocessed\

    One other odd thing I've noticed is I have the same version of unity on another desktop, it builds and deploys fine on that machine. I note the one which fails has 'holotoolkit' menu, and one which works does not

    AHHH! I see, so we have to do a
    for /r %F in (*.lock.json) do @(type "%F"|repl "v10.0.10240" "v10.0" >"%F.new"&move /y "%F.new" "%F" L >nul)
    batch script on the dir just above the build directory to replace all v10.0.10240's with v10.0's

    Same here, updated VS 2017 to version 15.3.2. Updated (reinstall) Unity to 2017.1.0f3. Now I get the following errors:

    I have both mentioned issues with 5.6.3f1. I've tried with both VS2015 and VS2017. VS2017 stops at the SerializationWeaver exception. VS2017 cannot find Assembly-CSharp.dll. Are both these issues fixed in upcoming release?

    What error are you seeing with VS2015? AFAIK that should be working correctly.

    The problem "Metadata file 'E:\UnityProjects\You\Temp\UnityVS_bin\Debug\Assembly-CSharp.dll' could not be found You Win.CSharp.Editor" happens to me too. But the reason was that Unity create a CSharp script with the same name. When I delete the twin file the error dissapers.
    I hope it helps!

    I have the same troubles . And I could not fix it for several days. So I reinstall win10,and reinstall VS and Unity. Then the sln files runs on VS without errors . HoloLens Emulator works well.
    The sln file of my project could not run on VS because I deleted some folders in C drive 【C:\Program Files (x86)\Windows Kits】, as follow picture.
    20171010211120.jpg
    BEFOR I delete the folder 【NETFXSDK】 sln file runs well on VS , but when I deleted it the errors occurred in Error list of VS, and the sln file failed to run.
    Hope that these are helpful to you.;)

    In VS (2015), go to the project dependencies (right click on the Solution -> Project Dependencies), and check Assembly-CSharp and Assembly-CSharp-firstpass.

    Worked for me.

    I hope this will help you :)

    Hi
    I also encountered similar issue recently after upgrading Unity from 5.6.1f1 to 2017.3.1. My Visual Studio 2017 version is 15.6.2.
    Supposedly my unity and Visual Studio should be immune to this issue since both versions are later than the original post.
    I also try the workaround on this link, but my NuGet package Manager setting has been checked correctly.
    http://www.imaginativeuniversal.com/blog/2017/06/24/hololens-fix-visual-studio-2017-build-error/
    May I know what I should do to solve it? Will it work if I downgrade to VS 2015?

    Hi,

    I'm still having this problem with Unity 2018.2.7f1 and VS Pro 201715.8.3

    The following is what shows on my error list.

    Severity Code Description Project File Line Suppression State Error CS0006
    Metadata file 'C:\Users\yizhong\Documents\HolographicAcademy-Holograms-230-SpatialMapping\HolographicAcademy-Holograms-230-SpatialMapping\Starting\230Test\App\230Test\GeneratedProjects\UWP\Assembly-CSharp\bin\x86\Debug\Assembly-CSharp.dll' could not be found 230Test C:\Users\yizhong\Documents\HolographicAcademy-Holograms-230-SpatialMapping\HolographicAcademy-Holograms-230-SpatialMapping\Starting\230Test\App\230Test\230Test\CSC 1 Active

    I've tried a few workarounds (except downgrading) but still having the problem. Any ideas?

    Thanks.

    Did you try building to a shorter path? The error is quite obvious:

    Code (csharp):
    1. The specified path, file name, or both are too long. The fully qualified file name must be less than 260 characters, and the directory name must be less than 248 characters.

    Hi, I run into the same problem when I deployed to my HoloLens. I'm using unity 2018.4.8f1. In the beginning I didn't applied any C# script to any components and it worked fine. Then I had this error when I applied the script to my cursor. I'm using the code from Microsoft tutorial.

    using UnityEngine;
    public class WorldCursor : MonoBehaviour
    {
    private MeshRenderer meshRenderer;
    // Use this for initialization
    void Start()
    {
    // Grab the mesh renderer that's on the same object as this script.
    meshRenderer = this.gameObject.GetComponentInChildren<MeshRenderer>();
    }
    // Update is called once per frame
    void Update()
    {
    // Do a raycast into the world based on the user's
    // head position and orientation.
    var headPosition = Camera.main.transform.position;
    var gazeDirection = Camera.main.transform.forward;
    RaycastHit hitInfo;
    if (Physics.Raycast(headPosition, gazeDirection, out hitInfo))
    {
    // If the raycast hit a hologram...
    // Display the cursor mesh.
    meshRenderer.enabled = true;
    // Move the cursor to the point where the raycast hit.
    this.transform.position = hitInfo.point;
    // Rotate the cursor to hug the surface of the hologram.
    this.transform.rotation = Quaternion.FromToRotation(Vector3.up, hitInfo.normal);
    }
    else
    {
    // If the raycast did not hit a hologram, hide the cursor mesh.
    meshRenderer.enabled = false;
    }
    }
    }

    Can you paste the contents of Visual Studio output window?
