HAA0502 Explicit new reference type allocation

问题

I have ASP.Net Core 2.1, C# application. I am using Clr Heap Allocation Analyzer

https://marketplace.visualstudio.com/items?itemName=MukulSabharwal.ClrHeapAllocationAnalyzer

One of the methods looks as below

Ex#1

public void ConfigureServices(IServiceCollection services) {

services.AddSingleton<IPocoDynamo>(serviceProvider => {
    var pocoDynamo = new PocoDynamo(serviceProvider.GetRequieredService<IAmazonDynamoDB>());
    pocoDynamo.SomeMethod();
    return pocoDynamo;
});

}

Ex.#2

public async Task<EventTO> AddEvent(EventTO eventObj)
{
  try
    {       
      throw new Exception("Error!");
    }
 catch (Exception ex)
 {
   Logger.Log(ex, eventObj);
   return null;
  }
}

I am using DI throughout the app. But wherever the analyzer is finding new keyword thing, it is warning as

HAA0502 Explicit new reference type allocation

Also wherever Lambda expression is used, it is warning as (like in ex#1)

Warning HAA0301 Heap allocation of closure Captures:

What is causing this & how to address this?

Thanks!
