System.Windows.Extensions doesn't reference System.Drawing.Common

  • บทความ

The System.Windows.Extensions package no longer references the System.Drawing.Common package.

Version introduced

.NET 8 Preview 7

Previous behavior

Previously, the System.Windows.Extensions package referenced the System.Drawing.Common package.

New behavior

Starting in .NET 8, the System.Windows.Extensions package no longer references the System.Drawing.Common package. If you depended on the System.Windows.Extensions package bringing in System.Drawing.Common, you might see a compilation error similar to this (but not necessarily for FontConverter):

error CS1069: The type name 'FontConverter' could not be found in the namespace 'System.Drawing'. 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.

Change category

This change can affect source compatibility.

Reason for change

This change avoids a dependency on System.Drawing.Common when System.Windows.Extensions is referenced.

This change helps more components remove a dependency on System.Drawing.Common unless they actually need it. For more information, see dotnet/msbuild issue 8962.

If you still need to use System.Drawing.Common, add a direct reference.
