Introduction

As a developer working with Visual Studio Code (VSCode) and the Devkit extension, you may encounter issues where certain features are not available in the editor. In this article, we will explore a specific problem where the Devkit features are not visible in the UnitTests editor, despite being available in other projects. We will delve into the possible causes and provide suggestions for resolving this issue.

Problem Description

The problem arises when working with a C# .Net 8 solution that contains multiple UnitTest projects (XUnit) inside. The solution file is not located at the root of the workspace, and when opening VSCode directly in that folder, the Devkit features are not visible in the UnitTests editor. The issue is not present in another project where the solution file resides at the root of the repository and contains only one UnitTest project.

Symptoms

No "play" button is available in the UnitTests editor.
CodeLens is not showing any information about the tests.
The tests are visible in the "Testing" view of VSCode, but double-clicking on them does not take you to the actual files.
When using the "Prefer C# extension" in the settings, CodeLens for Run/Debug is visible on the UnitTests, but the C#-Tests disappear from the "Testing"-View in VSCode entirely.

Possible Causes

Solution File Location: The solution file is not located at the root of the workspace, which may cause issues with the Devkit extension.
Multiple UnitTest Projects: The presence of multiple UnitTest projects within the solution may be causing the Devkit features to malfunction.
CSProj Files: The CSProj files may have differences that are not immediately apparent, which could be affecting the Devkit features.
Devkit Extension Configuration: The Devkit extension may not be properly configured, leading to the missing features.

Troubleshooting Steps

Verify Solution File Location: Ensure that the solution file is located at the root of the workspace. If not, try moving it to the root and see if the issue persists.
Check CSProj Files: Compare the CSProj files of the affected project with the one that is working as expected. Look for any differences in the project configuration.
Run "Try-Convert" Tool: Run the "try-convert" tool of the Devkit extension to see if it can resolve any issues.
Disable and Re-enable Devkit Extension: Try disabling and re-enabling the Devkit extension to see if it resolves the issue.
Check VSCode Settings: Verify that the "Prefer C# extension" setting is not enabled, as this may be causing the issue.
Reset VSCode Settings: Reset the VSCode settings to their default values to see if it resolves the issue.

Conclusion

The issue of missing Devkit features in the UnitTests editor can be frustrating, but by following the troubleshooting steps outlined above, you should be able to identify and resolve the problem. Remember to verify the solution file location, check the CSProj files, run the "try-convert" tool, disable and re-enable the Devkit extension, check the VSCode settings, and reset the VSCode settings to their default values. By taking these steps, you should be able to get the Devkit features working as expected in your UnitTests editor.

Additional Tips

Make sure to update the Devkit extension to the latest version to ensure you have the latest features and bug fixes.
If you are still experiencing issues, try reaching out to the Devkit community or the VSCode community for further assistance.
Consider creating a new project with a single UnitTest project to see if the issue is specific to your current project or a general issue with the Devkit extension.
