.Net Standard 2.0中的43个API是什么，但在.Net Framework 4.6.1中却没有？

题为.NET Standard API Reference的SO问题引用了https://github.com/dotnet/standard/issues/133中的讨论，提到了将包含在.Net Standard 2.0中但不受.Net Framework 4.6.1支持的43个API。但是，我无法在Internet上的任何地方找到这43个API的列表。我搜索到的最接近的是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，它列出了.Net Standard 1.5和1.6中引入的API。起初我以为我的搜索结束了，但后来我才意识到：

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

    3. 互联网上是否有任何地方，包含在.Net Standard 2.0中但未包含在.Net Framework 4.6.1中的43个特定 API的列表？

答案 0 :(得分：9)

使用https://apisof.net并针对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中列出的每个API进行检查，我设法将.Net Standard 1.6中存在的API列表放在一起，但遗漏了在.Net Framework 4.6.1中：

  • 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.Diagnostics.Tracing.EventSource：
    • public event EventHandler<EventCommandEventArgs> EventCommandExecuted（在.Net Framework 4.6.2中，但不是4.6.1）
  • System.IO.BufferedStream：
    • public int BufferSize { get; }（不在.Net Framework中）
    • public Stream UnderlyingStream { get; }（不在.Net Framework中）

  • System.Reflection.TypeInfo：以下所有API，其中没有一个在.Net Framework

    中 
    public virtual bool IsCOMObject { get; }
public override MemberTypes MemberType { get; }
public virtual StructLayoutAttribute StructLayoutAttribute { get; }
public ConstructorInfo TypeInitializer { get; }

  • System.Security.Cryptography.ECCurve：整个ECCurve结构，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中的新增功能，并且无法在.Net Framework 4.6.1（或4.6.2）中找到：

    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 brainpoolP512r1 { 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 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：不在.Net Framework
  • System.Security.Cryptography.ECPoint struct：不在.Net Framework
  • 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）

这比43个API要多得多。我还没有通过.Net Standard 2.0 API列表（它是巨大的）;一旦我这样做，我就会编辑这个答案，以反映我的发现。

答案 1 :(得分：3)

我在similar question

您可以在ApiCompatBaseline.net461.txt

中找到遗失的api

我检查了文件并找到了52个条目（超过43个！）。

我检查了大部分这些API，发现它们在net461中不可用，但在netstandard2中可用

缺少的API预计将在.Net Framework 7.1 .NET Framework 4.7.1 provides built-in support for .NET Standard 2.0

中实现

the .NET Framework 4.7.1 Early Access

2017年11月更新：

随着.NET Framework 4.7.1的最终版本的发布，4.6.1中所有缺失的API都已实现。

List of implemented API

现在.Net Standard 2.0内置于.NET Framework 4.7.1本身，无需安装.Net Standard 2.0支持的二进制文件。
