+Ignored assemblies.

+There are some assemblies we need to ignore because they include an implementation that doesn't work under mono.
+Mono provides its own implementation of those assemblies so it's safe to do so.
+
+The ignored_assemblies list is generated using tools/nuget-hash-extractor and feeding the problematic nugets to it.
+
+Right now the list of nugets are the ones that provide the assemblies in $ignored_assemblies_file_names.
+
+This is to be removed once a proper fix is shipped through nuget.
+
+Please keep this in sync with mcs/tools/xbuild/data/deniedAssembliesList.txt
+If any assemblies are added/removed, then this should be regenerated with:
