 ### Previous versions
 
-Previous versions of Visual Studio, including Visual Studio 2015, included a command-line code metrics tool called *Metrics.exe*. This previous version of the tool did a binary analysis, that is, an assembly-based analysis. The new tool analyzes source code instead. Because the new command-line code metrics tool is source code-based, the results are different to what's generated by previous versions of *Metrics.exe* and within the Visual Studio 2017 IDE.

 The new command-line code metrics tool computes metrics even in the presence of source code errors, as long as the solution and project can be loaded.
 
 #### Metric value differences
 
-The `LinesOfCode` metric is more accurate and reliable in the new *Metrics.exe*. It is independent of any codegen differences and doesn’t change when the toolset or runtime changes. The new *Metrics.exe* counts actual lines of code, including blank lines and comments.

-Other metrics such as `CyclomaticComplexity` and `MaintainabilityIndex` use the same formulas as previous versions of *Metrics.exe*, but the new *Metrics.exe* counts the number of `IOperations` (logical source instructions) instead of intermediate language (IL) instructions. The numbers will be slightly different from previous versions of *Metrics.exe* and from the Visual Studio 2017 IDE code metrics results.
