+These implicit namespaces may cause type conflicts. For example, if you're authoring an MSBuild task, and thus deriving from the abstract class, you'll see a conflict with the class. This conflict occurs because the namespace is implicitly included. The error looks similar to:
+
+```txt
+... error CS0104: 'Task' is an ambiguous reference between 'Microsoft.Build.Utilities.Task' and 'System.Threading.Tasks.Task'
+... error CS0115: 'SomeTask.Execute()': no suitable method found to override
+```
