I have a concurrent program to request crm, and then I found that the DisableCrossThreadSafeties property setting of CrmServiceClient supports concurrency, and found that setting it to true increases the concurrency efficiency by 50%. Is there any risk to crm or thread safety issues?

CrmServiceClient svc = new CrmServiceClient(ConfigurationManager.AppSettings["ConnStr"]);
svc.DisableCrossThreadSafeties = true;

Set to false: the total time-consuming program runs to completion, time-consuming: 164930 list count: 320 average each millisecond: 515

Set to true Total time-consuming program to run to completion, time-consuming: 79941 list count: 320 average each millisecond: 249

Hi,

CrmServiceClient itself is thread safe, but if you use DisableCrossThreadSafeties, it will cause thread safety issues.

You can refer to the official API documentation, here is a very clear statement:

CrmServiceClient.DisableCrossThreadSafeties Property (Microsoft.Xrm.Tooling.Connector) | Microsoft Docs

If this helped you, I'd appreciate it if you'd mark this as a Verified Answer, which may in turn help others as well.

Best Regards,
