Definition

Namespace:

Microsoft.EntityFrameworkCore

Assembly:

Microsoft.EntityFrameworkCore.dll

Package:

Microsoft.EntityFrameworkCore v8.0.0

Sets the ILoggerFactory that will be used to create ILogger instances for logging done by this context.

public virtual Microsoft.EntityFrameworkCore.DbContextOptionsBuilder UseLoggerFactory (Microsoft.Extensions.Logging.ILoggerFactory? loggerFactory);

abstract member UseLoggerFactory : Microsoft.Extensions.Logging.ILoggerFactory -> Microsoft.EntityFrameworkCore.DbContextOptionsBuilder
override this.UseLoggerFactory : Microsoft.Extensions.Logging.ILoggerFactory -> Microsoft.EntityFrameworkCore.DbContextOptionsBuilder

Public Overridable Function UseLoggerFactory (loggerFactory As ILoggerFactory) As DbContextOptionsBuilder

Parameters

loggerFactory

ILoggerFactory

The logger factory to be used.

Returns

DbContextOptionsBuilder

The same builder instance so that multiple calls can be chained.

Remarks

There is no need to call this method when using one of the 'AddDbContext' methods, including 'AddDbContextPool'. These methods ensure that the ILoggerFactory used by EF is obtained from the application service provider.

This method cannot be used if the application is setting the internal service provider through a call to UseInternalServiceProvider(IServiceProvider). In this case, the ILoggerFactory should be configured directly in that service provider.

See Using DbContextOptions and Logging for more information and examples.
