Module not found error when trying to install browsers (v1.42.0)

Have you tried deleting the bin/ folder? Might be similar to #2069.

[johnboygit]

just tried but it hasn't made any difference

[mxschmitt]

The issue you are observing is that there is an v1.41 (old) assembly trying to interact with a recent v1.42 Playwright driver.

Could you try deleting the obj folder as well? Do you maybe depend on multiple Playwright versions in your suite?

unfortunately that hasn't helped either.

I have a solution with two projects in it.

one project is a common one that has the playwright.net NuGet package. I build and publish a NuGet package from this to be consumed by any other test project in our organisation.

the other project in my solution is a simple test project that references the common project directly just to verify things are happy before I push and build the common one. this test project does not consume the playwright.net NuGet directly.

maybe this problem is only evident when a test project consumes playwright in this manner.

Update:

even if I run the browser install command from the output folder of the common project I get the same error so I don't think it has anything to do with one project referencing another

Would it be possible to share a reproduction with us which we can run locally? Otherwise we are unfortunately not able to act on it, thanks for your understanding.

Please try with the attached solution

I unfortunately was not able to reproduce, deleted obj/bin directory in both of the directories.

thanks. It seems to be working for me if I run powershell as admin so I'll close this issue.

I don't know why I didn't think of that before. I don't recall having to do it on previous upgrades.
