Running Playwright dotnet tests on Azure DevOps

I'm trying to execute Playwright dotnet tests with Nunit framework on Azure DevOps. I'm unable to execute testcases as and when I try to install playwright as a part of pipeline, there is an error thrown and build gets failed with the following message

Couldn't find project using Playwright. Ensure a project or a solution exists in D:\a\1\s, or provide another path using -p. Below is my azure pipeline steps, Can someone please help me where exactly the issue is and I have tried both Windows and latest Ubuntu agents

With Visual Studio projects you can add post-build-events, which will run on you dev machine and in the Azure Pipeline during a build (tested with VSBuild@1)

Example using the VS UI: (you will need to adjust paths for ubuntu)

echo $(TargetDir).playwright\node\win32_x64\playwright.cmd install
$(TargetDir).playwright\node\win32_x64\playwright.cmd install
echo Done

or adding directly to a.csproj

  <Target Name="PostBuild" AfterTargets="PostBuildEvent">
    <Exec Command="echo $(TargetDir).playwright\node\win32_x64\playwright.cmd install;$(TargetDir).playwright\node\win32_x64\playwright.cmd install;echo Done" />
  </Target>
