 Coverlet just uses the type name, so the attributes can be created under any namespace of your choosing.
 
+#### File Path  
+You can also ignore code coverage by specifing files using the `Exclude` property
+ - Use single or multiple paths (separate by comma)
+ - Use absolute or relative paths (relative to the project directory)
+ - Use file path or directory path with globbing (e.g `dir1/*.cs`)

+```bash
+dotnet test /p:CollectCoverage=true /p:Exclude=\"../dir1/class1.cs,../dir2/*.cs,../dir3/**/*.cs,\"
