DbContextOptionsBuilder.UseLoggerFactory(ILoggerFactory) DbContextOptionsBuilder.UseLoggerFactory(ILoggerFactory) DbContextOptionsBuilder.UseLoggerFactory(ILoggerFactory) Method


Sets the ILoggerFactory that will be used to create ILogger instances for logging done by this context. It is never necessary to call this method since EF can obtain or create a logger factory automatically.

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

Note that changing the logger factory can cause EF to build a new internal service provider, which may cause issues with performance. Generally it is expected that no more than one or two different instances will be used for a given application.

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.
