.NET WinForms：无法加载 System.Runtime

Question

我正在为一个想要简单地使用摩尔斯电码的朋友编写一个应用程序。

我试图使用我在摩尔斯电码支持下编写的外部库，当我尝试调用它时，我在外部“ Control.cs ”文件中收到此错误。 我发现在 Visual Studio 和 JB Rider 中都发生了这种情况，尽管 Visual Studio 给出了不同的错误，因为它无法调试外部源。

我的用途是：

using CainsSharpTools; // <= This is my Library
using System.Diagnostics;
using System.Windows.Forms;

我的 function 调用如下所示：

private void buttonEncode_Click(object sender, System.EventArgs e)
            => textBoxMorse.Text = MorseCode.Parse(textBoxPlain.Text).Value;

错误是

System.IO.FileLoadException: Could not load file or assembly 'System.Runtime, Version=4.2.2.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

我需要在我的 Lib 中使用 .NET Standard
