The ProviderAliasAttribute attribute has been moved from the Microsoft.Extensions.Logging assembly to the Microsoft.Extensions.Logging.Abstractions assembly.
Version introduced
.NET 10 Preview 4
Previous behavior
In previous versions of .NET, ProviderAliasAttribute was defined in the Microsoft.Extensions.Logging assembly.
New behavior
Starting in .NET 10, ProviderAliasAttribute is defined in Microsoft.Extensions.Logging.Abstractions and, to maintain compatibility, is type-forwarded from Microsoft.Extensions.Logging.
Type of breaking change
This change can affect source compatibility.
Reason for change
This change allows applications that depend on Microsoft.Extensions.Logging.Abstractions and that use ProviderAliasAttribute to avoid taking a dependency on the full Microsoft.Extensions.Logging package.
Recommended action
In most scenarios, no action is required. The type is type-forwarded from Microsoft.Extensions.Logging to Microsoft.Extensions.Logging.Abstractions, which allows existing code to continue to work without modification.
The only potential breaking scenario occurs when your project references an older version of Microsoft.Extensions.Logging alongside the .NET 10 version of Microsoft.Extensions.Logging.Abstractions. In this situation, a compilation error might occur due to ProviderAliasAttribute being defined in both assemblies. To resolve the error, upgrade to the .NET 10 version of Microsoft.Extensions.Logging.
