Compiler Error CS8410

'type': type used in an asynchronous using statement must be implicitly convertible to 'System.IAsyncDisposable' or implement a suitable 'DisposeAsync' method.

The expression inside an await using statement must have a DisposeAsync method.

To correct this error

Remove the await using keywords, or implement a suitable DisposeAsync method.

Example

using System.Threading.Tasks;

class Program
{
    static async Task Main()
    {
        // error CS8410: 'Example': type used in an asynchronous using statement
        // must be implicitly convertible to 'System.IAsyncDisposable' or implement
        // a suitable 'DisposeAsync' method.
        await using var example = new Example();
    }
}

class Example
{
}
