VSTHRD002: Analyzer unable to detect synchronous wait call in action parameter when the wrapping function return Task #632
Description
Bug description
Analyzer rule VSTHRD002 is unable to detect synchronous wait call in action parameter when the wrapping function return Task.
Repro steps
Use below code snippet:
using System;
using System.Linq;
using System.Threading.Tasks;
namespace vsthreadtest
{
class Program
{
static async Task Main(string[] args)
{
await FooAsync();
Foo1();
}
public static Task FooAsync()
{
Task.Delay(TimeSpan.FromSeconds(5)).Wait();
Enumerable.Range(1, 10).ToList().ForEach(i => { Task.Delay(TimeSpan.FromSeconds(5)).Wait(); });
return Task.CompletedTask;
}
public static void Foo1()
{
Enumerable.Range(1, 10).ToList().ForEach(i => { Task.Delay(TimeSpan.FromSeconds(5)).Wait(); });
}
}
}
Expected behavior
All Task.Delay(TimeSpan.FromSeconds(5)).Wait() calls should be detected by VSTHRD002
Actual behavior
Enumerable.Range(1, 10).ToList().ForEach(i => { Task.Delay(TimeSpan.FromSeconds(5)).Wait(); }) in FooAsync is not detected.
