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.

Hololens or WSA(UWP) use standalone DLL


I am developing the Hololens app.

There are several DLLs that work in the editor, and I have made the platform available to editors and WSA.

However, Hololens builds DLLNotFoundException as shown below.

       Loading IndyRP_DLL.dll
     Failed to load 'IndyRP_DLL.dll', expected x86 architecture, but was Unknown architecture. You must recompile your plugin for x86 architecture.

     (Filename: C:\buildslave\unity\build\Runtime/Misc/Plugins.cpp Line: 140)    


 DllNotFoundException: Unable to load DLL 'IndyRP_DLL': The specified module could not be found. (Exception from HRESULT: 0x8007007E)
    at IndyRP_DLL_UWP.Foo.Dll_JointCount()
    at DllManager.Init()
    at DllManager.$Invoke11(Int64 instance, Int64* args)
    at UnityEngine.Internal.$MethodUtility.InvokeMethod(Int64 instance, Int64* args, IntPtr method) 
 (Filename: <Unknown> Line: 0)
IndyRP_DLL_UWP is a wrapper dll for WSA (C ++ >> C #). IndyRP_DLL_UWP (C #) uses IndyRP_DLL (C ++) as the DLLImport function.

Both IndyRP and the other DLLs used the x86 architecture.

Is it impossible to use Standalone DLL in WSA?

What can I do?

    I made a mistake specifying the source code view

    IndyRP_DLL_UWP is a wrapper dll for WSA (C ++ >> C #). IndyRP_DLL_UWP (C #) uses IndyRP_DLL (C ++) as the DLLImport function.

  • Hey Sic,

    I'm having a very similar problem. Have you found a solution for this?
