未找到 PrivateFontCollection c# (linux) 中的错误

Question

I'm using command dotnet build in order to build a game in the MonoGame framework in Ubuntu 20.04 using .NET 5.0 . It was fine in Windows, but now that I'm using it here, it gives me this error:

error CS1069: The type name 'PrivateFontCollection' could not be found in the namespace 'System.Drawing.Text'. This type has been forwarded to assembly 'System.Drawing.Common, Version=0.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51' Consider adding a reference to that assembly. [/home/mrwoto/Ali/Programming/csharp/SAO/SAO/SAO.csproj]

So, is there anyway to resolve it? How can I add a reference to it in .csproj file?

Answer 1

One option is to add it from the terminal with

dotnet add package System.Drawing.Common

After this, you should be able to see something like the following in the .csproj file.

<PackageReference Include="System.Drawing.Common" Version="5.0.2" />

Please note that dotnet add is more than just adding some text to csproj.

From dotnet add package :

The dotnet add package command provides a convenient option to add a package reference to a project file. After running the command, there's a compatibility check to ensure the package is compatible with the frameworks in the project. If the check passes, a <PackageReference> element is added to the project file and dotnet restore is run.
