Options

Enabled                 Specifies whether or not coverage output is enabled
Exclude                 Filter expressions to exclude specific modules and types (multiple values)
Include                 Filter expressions to include specific modules and types (multiple values)
ExcludeByFile           Glob patterns specifying source files to exclude e.g. **/Migrations/* (multiple values)
ExcludeByAttribute      Attributes to exclude from code coverage (multiple values)
IncludeTestAssembly     Specifies whether to report code coverage of the test assembly

Both 'Exclude' and 'Include' options can be used together but 'Exclude' takes precedence.

You can ignore a method or an entire class from code coverage by creating and applying the [ExcludeFromCodeCoverage] attribute present in the System.Diagnostics.CodeAnalysis namespace.
You can also ignore additional attributes by adding to the 'ExcludeByAttributes' list (short name or full name supported) e.g. :
[GeneratedCode] => Present in System.CodeDom.Compiler namespace
[MyCustomExcludeFromCodeCoverage] => Any custom attribute that you may define

Filter Expressions

Wildcards
* => matches zero or more characters
		
Examples
[*]* => All types in all assemblies (nothing is instrumented)
[coverlet.*]Coverlet.Core.Coverage => The Coverage class in the Coverlet.Core namespace belonging to any assembly that matches coverlet.* (e.g coverlet.core)
[*]Coverlet.Core.Instrumentation.* => All types belonging to Coverlet.Core.Instrumentation namespace in any assembly
[coverlet.*.tests]* => All types in any assembly starting with coverlet. and ending with .tests

Both 'Exclude' and 'Include' options can be used together but 'Exclude' takes precedence.
