vb.net - .NET Core doesn't know about Windows 1252, how to fix?

Question

This program works just fine when compiled for .NET 4 but does not when compiled for .NET Core. I understand the error about encoding not supported but not how to fix it.

Public Class Program
    Public Shared Function Main(ByVal args As String()) As Integer
        System.Text.Encoding.GetEncoding(1252)
    End Function
End Class

Answer 1

To do this, you need to register the CodePagesEncodingProvider instance from the System.Text.Encoding.CodePages package.

To do that, install the System.Text.Encoding.CodePages package:

dotnet add package System.Text.Encoding.CodePages

Then (after implicitly or explicitly running dotnet restore) you can call:

Encoding.RegisterProvider(CodePagesEncodingProvider.Instance);
var enc1252 = Encoding.GetEncoding(1252);

Alternatively, if you only need that one code page, you can get it directly, without registration:

var enc1252 = CodePagesEncodingProvider.Instance.GetEncoding(1252);
