entre - ¿Cuáles son las 43 API que están en.Net Standard 2.0 pero no en.Net Framework 4.6.1?

net standard target framework

Question

La pregunta de SO titulada .NET Standard API Reference , citando la discusión en https://github.com/dotnet/standard/issues/133 , menciona 43 API que se incluirán en .Net Standard 2.0 pero no son compatibles con .Net Marco 4.6.1. Sin embargo, no he podido encontrar una lista de esas 43 API en ningún lugar de Internet. Lo más cercano que he encontrado en mi búsqueda es https://github.com/dotnet/standard/blob/master/docs/versions/netstandard1.5_diff.md y https://github.com/dotnet/standard/blob/master/docs/versions/netstandard1.6_diff.md , que enumera las API introducidas en .Net Standard 1.5 y 1.6. Al principio pensé que mi búsqueda había terminado, pero luego me di cuenta:

1. Hay más de 43 API en esas dos listas, y
2. Muchos de ellos ya son compatibles con .Net Framework 4.6.1.

¿Hay, en algún lugar de Internet, una lista de las 43 API específicas incluidas en .Net Standard 2.0 pero no incluidas en .Net Framework 4.6.1?

Answer 1

Publiqué una pregunta similar en el proyecto .Net Standard.

Puede encontrar las apis que faltan en: ApiCompatBaseline.net461.txt

Revisé el archivo y encontré 52 entradas (más de 43!).

Las 52 API que faltan son:

Revisé la mayoría de estas API y encontré que no están disponibles en net461, pero están disponibles en netstandard2

Se espera que las API faltantes se implementen en .Net Framework 7.1 .NET Framework 4.7.1 proporciona soporte integrado para .NET Standard 2.0

El .NET Framework 4.7.1 Acceso temprano

Actualización noviembre, 2017:

Con la versión final de .NET Framework 4.7.1 , se implementan todas las API que faltan en 4.6.1.

Lista de API implementadas

Ahora .Net Standard 2.0 está integrado directamente en .NET Framework 4.7.1 sin la necesidad de instalar .Net Standard 2.0 binarios compatibles.

Answer 2

Usando https://apisof.net y comparándolo con todas las API enumeradas en https://github.com/dotnet/standard/blob/master/docs/versions/netstandard1.5_diff.md y https://github.com/dotnet/standard/blob/master/docs/versions/netstandard1.6_diff.md , me las arreglé para armar una lista de las API presentes en .Net Standard 1.6 pero que faltan en .Net Framework 4.6.1:

• System.AppContext :
  • public static string TargetFrameworkName { get; } public static string TargetFrameworkName { get; } (no en .Net Framework)
  • public static object GetData(string name) (no en .Net Framework)

• System.Security.Cryptography.ECCurve : estructura ECCurve completa, y todo lo que contiene (incluida la clase estática System.Security.Cryptography.ECCurve.NamedCurves ), no están en .Net Framework. En otras palabras, todas las API en la siguiente lista son nuevas en .Net Core y no se pueden encontrar en .Net Framework 4.6.1 (o 4.6.2):

  public struct ECCurve {
      public enum ECCurveType {
          Characteristic2 = 4,
          Implicit = 0,
          Named = 5,
          PrimeMontgomery = 3,
          PrimeShortWeierstrass = 1,
          PrimeTwistedEdwards = 2,
      }
      public static class NamedCurves {
          public static ECCurve brainpoolP160r1 { get; }

          public static ECCurve nistP384 { get; }
          public static ECCurve nistP521 { get; }
      }
      public byte[] A;
      public byte[] B;
      public byte[] Cofactor;

      public bool IsNamed { get; }
      public bool IsPrime { get; }
      public Oid Oid { get; }
      public static ECCurve CreateFromFriendlyName(string oidFriendlyName);
      public static ECCurve CreateFromOid(Oid curveOid);
      public static ECCurve CreateFromValue(string oidValue);
      public void Validate();
  }

• System.Security.Cryptography.ECParameters struct: no en .Net Framework
• Estructura System.Security.Cryptography.ECPoint : no en .Net Framework
• System.Security.Cryptography.ECDsa :
  • public static ECDsa Create(ECCurve curve) (no en .Net Framework)
  • public static ECDsa Create(ECParameters parameters) (no en .Net Framework)
  • public virtual ECParameters ExportExplicitParameters(bool includePrivateParameters) (no en .Net Framework)
  • public virtual ECParameters ExportParameters(bool includePrivateParameters) (no en .Net Framework)
  • public virtual void GenerateKey(ECCurve curve) (no en .Net Framework)
  • public virtual void ImportParameters(ECParameters parameters) (no en .Net Framework)
• System.Text.RegularExpressions.Regex :
  • protected IDictionary CapNames { get; set; } protected IDictionary CapNames { get; set; } (no en .Net Framework)
  • protected IDictionary Caps { get; set; } protected IDictionary Caps { get; set; } (no en .Net Framework)

Eso es mucho más que 43 APIs. Todavía no he revisado la lista de API de .Net Standard 2.0 (es enorme ); Una vez que lo haga, editaré esta respuesta para reflejar lo que encuentro.
