Sometimes, you don't want to know coverage data solution-wide. For example, you may not be interested in coverage statistics for code marked with ObsoleteAttribute or a specific legacy project. In this case you can set global or solution-specific coverage filters based on project, namespace, type, or type member names. Attribute filters are also available that restrict gathering coverage information to code marked (or not marked) with certain attributes. Alternatively, if you already have coverage data collected, you can choose to exclude a specific node from the coverage tree. As soon as you do this, dotCover will instantly recalculate coverage statistics.
