win32 exceptions when running on mac/linux

[HaoK]

Hi, we are trying to use playwright sharp to do some of our E2E testing for Blazor on Asp.Net.Core, its working pretty great for Windows (see https://github.com/dotnet/aspnetcore/pull/30113), but we are running into some issues getting this to work on mac/linux. (https://github.com/dotnet/aspnetcore/pull/30404)

The overview of how our testing works right now is, our ci jobs build a single test payload via dotnet publish on windows, which we send to different test machines that run our tests, so windows, ubuntu, osx. I've tried a few different options to try and get playwright sharp working on mac/nix but so far none of these have worked:

• Run Playwright.InstallAsync on the test machine before running the test payload)
• Install playwright-sharp-tool and install browsers

Looking for some guidance for the best way to make this work.

Example Win32 exception error on ubuntu (is this because we ran the output of something published from windows?)

Hey @HaoK, First, the Win32Exception is an exception thrown by the Process class, no matter the platform :) Could you try v0.191.0? We changed the way we are deploying the driver. Maybe that might help.

[HaoK]

Cool I'm trying 191.1 now, I've verified that the drivers are getting delivered in the payload to the helix machines in the .playwright directory, and I'm hardcoding the paths to the root directory (that contains the .playwright),

I'm still seeing some errors, am I passing in the correct path for the driver path that you expect? C:\h\w\B70A09E6\w\9E8B096E\e\.playwright contains the drivers, previously it would throw a cannot find drivers exception, so this is progress!

Install code

                Console.WriteLine($"Installing Playwright to Browsers: {EnvironmentVariables["PLAYWRIGHT_BROWSERS_PATH"]} Drivers: {EnvironmentVariables["PLAYWRIGHT_DRIVER_PATH"]}");
                await Playwright.InstallAsync(EnvironmentVariables["PLAYWRIGHT_BROWSERS_PATH"]);                    await Playwright.InstallAsync(EnvironmentVariables["PLAYWRIGHT_BROWSERS_PATH"], EnvironmentVariables["PLAYWRIGHT_DRIVER_PATH"]);

On linux/mac there's an error about FileName property

I believe this has been resolved in https://www.nuget.org/packages/Microsoft.Playwright/1.11.1-alpha-2. Please file a new issue if this still happens.
