Cake.Bakery logging output does not get displayed in VS Code

[nikola-nignite]

Cake.Bakery logging is not turned on when it gets launched by OmniSharp.

Cake.Scripting.Transport.Tcp.Client.ScriptGenerationProcess will never pass --verbose argument to Cake.Bakery.exe.

Reason:

1. Cake.Scripting.Transport uses LoggerFactory which is passed to it by OmniSharp.
2. Bakery ScriptGenerationProcess expects following condition to be met in order to enable verbose logging:

if (_logger.IsEnabled(LogLevel.Debug))
{
    arguments += " --verbose";
}

3. OmniSharp has logging filter which will never enable any logging from non OmniSharp namespaces as follows (CompositionHostBuilder.cs):

services.AddLogging(builder =>
{
    var workspaceInformationServiceName = typeof(WorkspaceInformationService).FullName;
    var projectEventForwarder = typeof(ProjectEventForwarder).FullName;

    builder.AddFilter(
        (category, logLevel) =>
            environment.LogLevel <= logLevel &&
// NOTICE BELOW LINE. Condition from point #1 of this bug report will always return false. Category is Cake.Scripting.Transport.Tcp.Client.ScriptGenerationProcess
            category.StartsWith("OmniSharp", StringComparison.OrdinalIgnoreCase) &&
            !category.Equals(workspaceInformationServiceName, StringComparison.OrdinalIgnoreCase) &&
            !category.Equals(projectEventForwarder, StringComparison.OrdinalIgnoreCase));

    configureLogging?.Invoke(builder);
});

This could be considered a bug either in OmniSharp (due to log filter) or Cake.Bakery ScriptGenerationProcess.

Some options are:

• Allow external configuration of logging, beside command line
• For assembles which are hosted in OmniSharp process, rename namespaces to start with OmniSharp
