Question:
How to address 'This async method lacks 'await' operators’?

The warning "This async method lacks 'await' operators" typically occurs when you declare a function with the async keyword but don't actually use await inside the function. The purpose of async functions is to allow the use of await to handle promises in a synchronous-looking way.


To address this warning, you have to remove async from your derived classes and return a value using Task.FromResult()


Base:

public virtual async Task<TagBuilder> RenderAsync(int columnWidth)

{

    // ...

}


Derived:

public override Task<TagBuilder> RenderAsync(int columnWidth)

{

    TagBuilder tag = GetTag();

    return Task.FromResult(tag);

}
