CS1061 'AllureLifecycle' does not contain a definition for 'AddAttachment' and no accessible extension method 'AddAttachment' accepting a first argument of type 'AllureLifecycle' could be found (are you missing a using directive or an assembly reference?) ATFramework (net6.0)

[Roman-Tretiakov]

I installed Allure.Net.Commons as alternative of Allure.Commons. And my old code doesn't work when I try to add screen shot attachment :
AllureLifecycle.Instance.Attachment("Screenshot", "image/png", screenshotPath);

I have got following error: CS1061 'AllureLifecycle' does not contain a definition for 'AddAttachment'
I try to use AttachmentAsync method instead, but result is the same. Please help me.

Please, use the AllureApi class instead:

AllureApi.AddAttachment("Screenshot", "image/png", screenshotPath)

It's in the Allure.Net.Commons namespace. You should add the following using statement at the top of the file:

using Allure.Net.Commons;

Thanks, I had the same issue.

I get this error when I use the above suggested code. How can I fix this

Make sure Allure.NUnit and Allure.Net.Commons packages both have the same version
