Some dlls are missing in windows 2019 server

Occasional Visitor


We are using web application (.aspx) which built on dotnet framework 4.7.2.

The following .dlls were not found/missing in windows 2019 server.

1. system.text.encoding.codepages.dll

2. system.runtime.compilerservices.unsafe.dll

Do you know why above 2 dlls were missing?


Are these dlls part of dotnet framework 4.7.2 runtime?


Kindly provide your inputs.
