How to use PuppeteerSharp inside an UWP App?

Question

I'm trying to use PuppeteerSharp inside an UWP app. All the dependencies seem fine but I got a permission problem with the location of chromium.

Access to the path "{AppRoot}\bin\x86\Debug\AppX\.local-chromium" is denied.

File permission is very restricted in UWP but my app has broadFileAccess anyways. The only thing is that I can only open a file with some kind of user interaction like a picker.

Is there a way to work around this?

How to use PuppeteerSharp inside an UWP App?

PuppeteerSharp does not support in UWP, You could check PuppeteerSharp source code to verify this. This is DownloadsFolder = Path.Combine(Directory.GetCurrentDirectory(), ".local-chromium") and matched path is "{AppRoot}\bin\x86\Debug\AppX.local-chromium". In the following code we call Create method in it, but above path is read-only in UWP.

    public async Task<RevisionInfo> DownloadAsync(int revision)
    {
        var url = GetDownloadURL(Platform, DownloadHost, revision);
        var zipPath = Path.Combine(DownloadsFolder, $"download-{Platform.ToString()}-{revision}.zip");
        var folderPath = GetFolderPath(revision);

        if (new DirectoryInfo(folderPath).Exists)
        {
            return RevisionInfo(revision);
        }

        var downloadFolder = new DirectoryInfo(DownloadsFolder);
        if (!downloadFolder.Exists)
        {
            downloadFolder.Create();
        }

        if (DownloadProgressChanged != null)
        {
            _webClient.DownloadProgressChanged += DownloadProgressChanged;
        }
        await _webClient.DownloadFileTaskAsync(new Uri(url), zipPath).ConfigureAwait(false);

        if (Platform == Platform.MacOS)
        {
            //ZipFile and many others unzip libraries have issues extracting .app files
            //Until we have a clear solution we'll call the native unzip tool
            //https://github.com/dotnet/corefx/issues/15516
            NativeExtractToDirectory(zipPath, folderPath);
        }
        else
        {
            ZipFile.ExtractToDirectory(zipPath, folderPath);
        }

        new FileInfo(zipPath).Delete();

        var revisionInfo = RevisionInfo(revision);

        if (revisionInfo != null && GetCurrentPlatform() == Platform.Linux)
        {
            LinuxSysCall.Chmod(revisionInfo.ExecutablePath, LinuxSysCall.ExecutableFilePermissions);
        }
        return revisionInfo;
    }
