 The trimmer is always enabled for all size sensitive .NET workloads like Blazor WebAssembly, Xamarin or .NET mobile and can be manually enabled for other project types. The default apps trimming setting can be further customized by using a number of [msbuild properties](https://learn.microsoft.com/dotnet/core/deploying/trimming-options).
 
-## Trimming Lens
-
-The [tlens](src/tlens/README.md) is another tool for developers which can be used to explore ways to reduce the size of trimmed apps or exploring libraries readiness for trimming. The tool produces a recommendation where the compiled source could be improved to produce even smaller outputs when trimmed using the trimmer.

 ## Source Code Analyzer
 
 Another tool available for developers is implemented as [Roslyn Analyzer](src/ILLink.RoslynAnalyzer) which runs on source code and warns developers about code patterns and APIs which are problematic when building code which could be used with trimmed apps.
