Unhandled Exception: System.TypeLoadException after I put a plugin.

I'm developing a simple game running on Surface Pro 3, and need the gyro data from surface pro. I'm following this tutorial https://unity3d.com/learn/tutorials/modules/beginner/live-training-archive/writing-plugins and created a plugin to return the gyro data. Yet when I try to access its methods through the plugin, the compilation fails with following error message:

Unhandled Exception: System.TypeLoadException: Could not load type 'gyroTest.myGyro' from assembly 'gyroTest, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'.

I think it's because I use Windows.Devices.Sensors in the plugin, which Unity does not supports, but I'm not quite sure how to solve it. Thank you!

 

Thank you for your reply. However, I followed the step in first link and it still have the same error message

 

It happens when I click Play

 

I made the Editor plugin not access any WinRT APIs and the error doesn't happen anymore. Every other setting is according to the link you posted. However, since the editor plugin is not accessing WinRT APIs anymore, I removed the code that requires Win API and put it as the Editor Plugin, and the objects in Unity behaves according to the Editor version instead of Plugins/WSA/plugin's version. Can you point out where I did wrong?

 

Hi Thomas, I tried to build for WSA as VS project but it still fails with new error messages. The link is to the zip file of the project,

it simple try to read x accelerometer data from Surface Pro and print it on the screen.

Thank you.

 

I used Unity 5.1.0f3 and Windows SDK 8.1 These are the errors I got:


C:\TempFolder is where I build the project to.

 

I tried to build in Visual Studio, build doesn't have any errors, but once I clicked Play Local Machine, its output is:

Then I did according to: https://cyanbyfuchsia.wordpress.com...e-arm-but-this-computer-has-architecture-x64/

And get more errors:

 

It creates same problem as the second screen shot.

 

Here is the output after I clicked build:
