你大概知道System.Drawing，它是一个执行图形相关任务的流行的API，同时它也不属于.NET Core的一部分。最初是把.NET Core作为云端框架设计的，它不包含非云端相关API。另一方面，.NET Core是跨平台框架，它不包含任何操作系统特定的API，例如Windows上的Active Directory活动目录 。再者，.NET Core也不包括类似，作为.NET framework一部分的，ConfigurationManager这样的诸多API。
在我之前的文章中，我已经描述了如何将这些API用于.NET Core和.NET标准应用程序。
为了实现这一点，有一个称为Windows Compatibility Pack的元包。但是，这个元包包含许多与Windows相关的API（作为包分发）。在这个元包里面有一个System.Drawing.Common包。
为了在.NET Core中使用绘图功能，请在Nuget包添加引用：
<PackageReference Include="System.Drawing.Common" Version="4.5.0-preview1-**" >
在这之后，你将可以运行例如以下的代码。
int x = 100;
Image image = new Bitmap(2000, 1024);
Graphics graph = Graphics.FromImage(image);
graph.Clear(Color.Azure);
Pen pen = new Pen(Brushes.Black);
graph.DrawLines(pen, new Point[] { new Point(10,10), new Point(800, 900) });
graph.DrawString("Hello drawing from .NET Core :)",
new Font(new FontFamily("DecoType Thuluth"), 20, FontStyle.Bold),
Brushes.Blue, new PointF(150, 90));
image.Save("graph.jpeg", System.Drawing.Imaging.ImageFormat.Png);
在你运行上述代码之后，你将看到如下图片：
