Chromium Edge driver on Ubuntu version of Edge

Question

So we got edge to work on Ubuntu and connect it to a selenium hub 4 (on the official hub 4 docker image) and everything's all fine there.

Now when it comes to the actual code of the C# tests, things are weird. First off, there are 2 packages for the Edge driver.

1. From OpenQA,
2. From Microsoft

If we try to use the one from Microsoft, selenium complains that the EdgeOptions do not have the method .ToCapabilities() (which it doesn't) and we cannot register a RemoteWebDriver

If we use the OpenQA version, we can hit the hub but we get this:

System.InvalidOperationException: 'Unable to create session for <CreateSessionRequest with Capabilities {browserName: MicrosoftEdge, ms:edgeChromium: true, ms:edgeOptions: {}, pageLoadStrategy: normal}>
Build info: version: '4.0.0-alpha-7', revision: 'bd15e4e88a'
System info: host: '9a1032dfe0c9', ip: 'x.x.x.x', os.name: 'Linux', os.arch: 'amd64', os.version: '4.19.76-linuxkit', java.version: '1.8.0_265'
Driver info: driver.version: unknown
Build info: version: '4.0.0-alpha-7', revision: 'bd15e4e88a'

Driver info: driver.version: unknown (SessionNotCreated)'

The setup is the following:

• The browser is in a docker container with Ubuntu running (the browser was tested with VNC and it works)
• The hub is on the official Selenium 4 docker container
• The tests or on a separate docker container running .Net Core 2.2

Does anyone have any examples of how to initialize the driver from C# to actually run tests?
