.net - .Net Standard 2.0 中包含但 .Net Framework 4.6.1 中没有的 43 个 API 是什么？

Question

题为 .NET Standard API Reference 的问题，引用https://github.com/dotnet/standard/issues/133中的讨论，提到 43 个 API 将包含在 .Net Standard 2.0 中，但不受 .Net Framework 4.6.1 支持。但是，我无法在 Internet 上的任何地方找到这 43 个 API 的列表。我在搜索中最接近的是 https://github.com/dotnet/standard/blob/master/docs/versions/netstandard1.5_diff.md和 https://github.com/dotnet/standard/blob/master/docs/versions/netstandard1.6_diff.md ，其中列出了 .Net Standard 1.5 和 1.6 中引入的 API。起初我以为我的搜索结束了，但后来我意识到:

1. 这两个列表中有超过 43 个 API，并且
2. 其中许多已受 .Net Framework 4.6.1 支持。

互联网上任何地方是否存在 .Net Standard 2.0 中包含但 .Net Framework 4.6.1 中未包含的 43 个特定 API 的列表？

Answer 1

通过使用https://apisof.net并根据https://github.com/dotnet/standard/blob/master/docs/versions/netstandard1.5_diff.md中列出的每个API进行检查和 https://github.com/dotnet/standard/blob/master/docs/versions/netstandard1.6_diff.md ，我设法整理了 .Net Standard 1.6 中存在但 .Net Framework 4.6.1 中缺失的 API 列表:

• System.Diagnostics.Tracing.EventCounter :
  • public EventCounter(string name, EventSource eventSource) (不在 .Net Framework 中)
  • public void WriteMetric(float value) (不在 .Net Framework 中)

• System.IO.BufferedStream :
  • public int BufferSize { get; } (不在 .Net Framework 中)
  • public Stream UnderlyingStream { get; } (不在 .Net Framework 中)

• System.AppContext :
  • public static string TargetFrameworkName { get; } (不在 .Net Framework 中)
  • public static object GetData(string name) (不在 .Net Framework 中)
• System.Linq.Enumerable :
  • public static IEnumerable<TSource> Append<TSource>(this IEnumerable<TSource> source, TSource element) (不在 .Net Framework 中)
  • public static IEnumerable<TSource> Prepend<TSource>(this IEnumerable<TSource> source, TSource element) (不在 .Net Framework 中)

• System.Security.Cryptography.ECCurve :整个ECCurve struct 及其中的所有内容(包括 System.Security.Cryptography.ECCurve.NamedCurves 静态类)都不在 .Net Framework 中。换句话说，以下列表中的所有 API 都是 .Net Core 中新增的，在 .Net Framework 4.6.1(或 4.6.2)中找不到:

  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 brainpoolP160t1 { get; }

          public static ECCurve brainpoolP512t1 { get; }
          public static ECCurve nistP256 { get; }
          public static ECCurve nistP384 { get; }
          public static ECCurve nistP521 { get; }
      }
      public byte[] A;
      public byte[] B;

      public byte[] Seed;
      public bool IsCharacteristic2 { get; }
      public bool IsExplicit { get; }
      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 结构:不在 .Net Framework 中
• System.Security.Cryptography.ECPoint 结构:不在 .Net Framework 中
• System.Security.Cryptography.ECDsa :
  • public static ECDsa Create(ECCurve curve) (不在 .Net Framework 中)
  • public static ECDsa Create(ECParameters parameters) (不在 .Net Framework 中)
  • public virtual ECParameters ExportExplicitParameters(bool includePrivateParameters) (不在 .Net Framework 中)
  • public virtual ECParameters ExportParameters(bool includePrivateParameters) (不在 .Net Framework 中)
  • public virtual void GenerateKey(ECCurve curve) (不在 .Net Framework 中)
  • public virtual void ImportParameters(ECParameters parameters) (不在 .Net Framework 中)
• System.Text.RegularExpressions.Regex :
  • protected IDictionary CapNames { get; set; } (不在 .Net Framework 中)
  • protected IDictionary Caps { get; set; } (不在 .Net Framework 中)

这远远超过 43 个 API。我还没有浏览过 .Net Standard 2.0 API 列表(它巨大)；一旦完成，我将编辑此答案以反射(reflect)我的发现。
