My current specific situation is that I want to use DataContractSerializer Class in a library supporting .NETStandard1.3. I am unable to reference it in the library. The document gives me an impression that it is a part of .Net Standard Library. Could you anyone offer a tip on how to determine if a class is supported by .Net Standard Library?
Your one-stop shop for all .NET-based APIs .NET API Browser
- select .Net Standard
- select version
- Enter your search: DataContractSerializer
You find DataContractSerializer in .Net Standard 2.0 only
The first version supporting that is .NET Standard 2.0.
You can search at apisof to find out what frameworks contain an API.
You are looking at the .NET Core docs.
In the .NET Support chart:
you can see that NetStandard1.3 does not support .NET Core. You'd have to move up to 2.0
