WinRTError: Unknown runtime error when referencing a c# component from javascript
I'm attempting to access a C# component in UWP, but I get an unhelpful error when doing so: WinRTError: Unknown runtime error. Why does this error occur, and how can I stop it?
I'm using Windows 10, VS 2017, and building my project to meet the minimum version of 10.0.16299.0
Here's a MVCE showing the behavior: https://github.com/re-jim/UWPComponentSample
The C# component is set as a reference in my Javascript component.
Javascript:
The below function triggers the C# component, which should zip a directory
async zip(content)
try
console.log('ZipComponent is ', ZipComponent)
console.log('function is ', ZipComponent.ZipWorker.zipDirectory)
ZipComponent.ZipWorker.zipDirectory(content.dirPath, content.dirPath + '\file.ezdrm')
catch (err)
console.log('err is ',err)
I've console.logged the component and the method I intend to use to show that exists:
C#
using System;
using System.Diagnostics;
using System.IO.Compression;
namespace ZipComponent
public sealed class ZipWorker
public static void ZipDirectory(string folderPath, string outputFile)
try
Debug.WriteLine("zippping " + folderPath + " output " + outputFile);
ZipFile.CreateFromDirectory(folderPath, outputFile);
catch (Exception e)
Debug.Write(e);
public static void UnzipDirectory(string zipFile, string outputPath)
try
Debug.WriteLine("unzippping " + zipFile + " output " + outputPath);
ZipFile.ExtractToDirectory(zipFile, outputPath);
catch (Exception e)
Debug.Write(e);
I don't see the output from Debug.WriteLine in my output
The code inside of ZipDirectory() doesn't seem to be causing the error. I replaced the function with:
public static string ZipDirectory()
return "hello world"
after also editing the javascript function call to match, And that gives me the same error as below.
