Suggestion: Visual Studio OpenTAP SDK includes Editor CE

Just choose OpenTAP UI. Once your project is created, select your project. Add next in the project file:

<AdditionalOpenTapPackage Include="Deverloper's System CE" />

Maybe your file already includes “Deverloper’s System”. In that case update it to CE version.

Community version should not be used.
