No Selenium.WebDriver.MSEdgeDriver for Edge browser version 137 and 138

[michasanyi]

Dear Owners,

The driver versions for Edge browser version 137 and 138 are not existing yet, however these versions are already on the market.
Our company policy automatically updates the browsers on our test machine to the latest version, and that's why all tests fail until the driver of proper version is existing.

Could you launch the drivers of new versions, please?

Thanks in advance,

Hi @michasanyi , you may find the latest version of msedgedriver in this link: https://developer.microsoft.com/en-us/microsoft-edge/tools/webdriver/?form=MA13LH

Hi guangyuexu, Thanks for your quick answer. In our continuous integration the web drivers are downloaded with NuGet restore step. I'm afraid of that the location you adviced is not eligible for that purpose. Guangyue Xu ***@***.***> ezt írta (időpont: 2025. jún. 27., P 20:14):

Hi @michasanyi , Selenium.WebDriver.MSEdgeDriver is not maintained by Microsoft. You may reach out to the owner of the package to update the binaries.

I am getting a similar error.

I had a similar issue where my Selenium.WebDriver only supported Edge 134. I was able to work around it by downloading the edge driver from Microsoft. I placed the exe in a local directory to test. The Selenium.WebDriver is able to load Chrome 138 now.

You can specify the folder to load the edge driver:

var options = new EdgeOptions();
var service = EdgeDriverService.CreateDefaultService(@"C:\EdgeDriver");
using(var driver = new EdgeDriver(service, options))

Yes, this is a good workaround, but I think Selenium.WebDriver should support the latest version of Edge.
