The member 'Utility.ConnectAsync()' does not hide an accessible member. The new keyword is not required.

This async method lacks 'await' operators and will run synchronously. Consider using the 'await' operator to await non-blocking API calls, or 'await Task.Run(...)' to do CPU-bound work on a background thread.

Possible null reference return.

Because this call is not awaited, execution of the current method continues before the call is completed. Consider applying the 'await' operator to the result of the call.

Converting null literal or possible null value to non-nullable type.

Because this call is not awaited, execution of the current method continues before the call is completed. Consider applying the 'await' operator to the result of the call.

Non-nullable field '_receiveMessageTask' must contain a non-null value when exiting constructor. Consider declaring the field as nullable.

Non-nullable field '_connectionTask' must contain a non-null value when exiting constructor. Consider declaring the field as nullable.

Using member 'System.Text.Json.JsonSerializer.Deserialize<TValue>(String, JsonSerializerOptions)' which has 'RequiresDynamicCodeAttribute' can break functionality when AOT compiling. JSON serialization and deserialization might require types that cannot be statically analyzed and might need runtime code generation. Use System.Text.Json source generation for native AOT applications.

Using member 'System.Text.Json.JsonSerializer.Deserialize<TValue>(String, JsonSerializerOptions)' which has 'RequiresUnreferencedCodeAttribute' can break functionality when trimming application code. JSON serialization and deserialization might require types that cannot be statically analyzed. Use the overload that takes a JsonTypeInfo or JsonSerializerContext, or make sure all of the required types are preserved.
