CRR0041 - Use Task.Run instead of Task.Factory.StartNew

• Oct 11, 2021

This analyzer detects Task.Factory.StartNew thread execution statements that can be unsafe.

C#

Task.Factory.StartNew(() => { DemoMethodSync(); });

VB.NET

Task.Factory.StartNew(Sub() DemoMethodSync())

To fix the issue, use the Task.Run method instead of Task.Factory.StartNew.

C#

Task.Run(() => { DemoMethodSync(); });

VB.NET

Task.Run(Sub() DemoMethodSync())
