DbContextOptionsBuilder.EnableThreadSafetyChecks(Boolean) Method
Definition

Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.
Disables concurrency detection, which detects many cases of erroneous concurrent usage of a DbContext instance and causes an informative exception to be thrown. This provides a minor performance improvement, but if a DbContext instance is used concurrently, the behavior will be undefined and the program may fail in unpredictable ways.
public virtual Microsoft.EntityFrameworkCore.DbContextOptionsBuilder EnableThreadSafetyChecks (bool enableChecks = true);abstract member EnableThreadSafetyChecks : bool -> Microsoft.EntityFrameworkCore.DbContextOptionsBuilder
override this.EnableThreadSafetyChecks : bool -> Microsoft.EntityFrameworkCore.DbContextOptionsBuilderPublic Overridable Function EnableThreadSafetyChecks (Optional enableChecks As Boolean = true) As DbContextOptionsBuilderParameters
- enableChecks
- Boolean
Returns
The same builder instance so that multiple calls can be chained.
Remarks
Only disable concurrency detection after confirming that the performance gains are considerable, and the application has been thoroughly tested against concurrency bugs.
Note that if the application is setting the internal service provider through a call to UseInternalServiceProvider(IServiceProvider), then this option must configured the same way for all uses of that service provider. Consider instead not calling UseInternalServiceProvider(IServiceProvider) so that EF will manage the service providers and can create new instances as required.
