Breaking changes
New parameter ExcludeAssembliesWithoutSources to control automatic
assembly exclusion
[coverlet-coverage/coverlet#1164.
The parameter InstrumentModulesWithoutLocalSources has been removed.
since it can be handled by setting ExcludeAssembliesWithoutSources to
None.
The default heuristics for determining whether to instrument an assembly
has been changed. In previous versions any missing source file was taken
as a signal that it was a third-party project that shouldn't be
instrumented, with exceptions for some common file name patterns for
source generators. Now only assemblies where no source files at all can
be found are excluded from instrumentation, and the code for detecting
source generator files have been removed. To get back to the behaviour
that at least one missing file is sufficient to exclude an assembly, set
ExcludeAssembliesWithoutSources to MissingAny, or use assembly exclusion
filters for more fine-grained control.
