Question

I am a manual tester, but started my journey to learn Playwright with C#.net, I installed Visual Studio community edition and .NET 8.0 SDK and set the Environment variable as mentioned in the few articles here, but when I try to open this project to the visual studio, then get the error: The selected file cannot be opened as a solution or project. Please select a solution file or a project file.

Answer 1

Follow the steps as mentioned in this page on official playwright site

Step 1 to 4 will help you running the first program even without opening any IDE and building your code.

Once that works open the solution file/folder from the IDE rather than opening the file by clicking on it.
