-# This file includes OneCore powershell CoreCLR references. Do not import this file directly. It is automatically imported
-# when MANAGED_PROFILE=PowerShell is specified in sources file.
-#
-# This file is also depended on by the tool 'TypeCatalogGen.exe'. The tool tries to parse this file to get the list of reference 
-# assemblies used by OneCore powershell, and then use that list to generate the CSharp code for initializing the CoreCLR type
-# catalog cache. That CSharp code will be compiled into 'Microsoft.PowerShell.CoreCLR.AssemblyLoadContext.dll' during the build.
-# For more information about 'TypeCatalogGen.exe', see its source code under 'PSAssemblyLoadContext\TypeCatalogGen'.
-#
-# The parsing rule of this file in 'TypeCatalogGen.exe' is very simple:
-#   - Read each line of this file and trim it;
-#   - Skip comment lines;
-#   - Match the line with the regular expression pattern '^\$\(PS_PROFILE_REF_PATH\)\\(.+);\s*\\$'
-# So when adding new reference assembly entries, please make sure the new lines match the above pattern.
