所以，我必须使用C＃进行单一课程，就像我必须使用MSSQL Server一样，最大的问题是我正在运行Ubuntu。我跟着this指南，我的意思是它来自微软对吗？无法使用任何System.Windows.Form，无论是SqlDataAdapter还是其他更多（如99.65％的库）。 有没有人遇到过这个问题？或者您刚刚创建了一个虚拟机并等待一周时间进行Visual安装？
这是我运行dotnet run
Program.cs(4,22): error CS0234: The type or namespace name 'Forms' does not exist in the namespace 'System.Windows' (are you missing an assembly reference?) [/home/potra/Desktop/School/School/DBMS/Test/Test.csproj]
Program.cs(8,28): error CS0246: The type or namespace name 'Form' could not be found (are you missing a using directive or an assembly reference?) [/home/potra/Desktop/School/School/DBMS/Test/Test.csproj]
Program.cs(10,17): error CS0246: The type or namespace name 'DataGridView' could not be found (are you missing a using directive or an assembly reference?) [/home/potra/Desktop/School/School/DBMS/Test/Test.csproj]
Program.cs(11,17): error CS0246: The type or namespace name 'DataGridView' could not be found (are you missing a using directive or an assembly reference?) [/home/potra/Desktop/School/School/DBMS/Test/Test.csproj]
Program.cs(12,17): error CS0246: The type or namespace name 'SqlDataAdapter' could not be found (are you missing a using directive or an assembly reference?) [/home/potra/Desktop/School/School/DBMS/Test/Test.csproj]
The build failed. Please fix the build errors and run again.

最新的.NET Core，2.1 Preview 2，does not include System.Windows.Forms。
如果您想使用原生Ubuntu运行时，Mono supports WinForms和SqlClient。
