LZ4EncoderStream Dispose Issue

[rajeshgaddam17]

Description
Trying to use LZ4EncoderStream to compress and decompress but when using it we are getting below exception
System.Net.Http.HttpRequestException : Error while copying content to a stream.
----> System.IO.IOException : No message provided
----> System.InvalidOperationException : Synchronous operations are disallowed. Call WriteAsync or set AllowSynchronousIO to true.

To reproduce
Calling this method context.HttpContext.Response.Body.WriteAsync(byteArray, 0, byteArray.Length);

and it is using LZ4Stream.Encode(stream, null, leaveOpen: true); method to do the job but it is failing with above exception.

I have analysed the LZ4EncoderStream.cs class and it is trying to use DisposeAsync() method and inside that it is using _writer.Dispose() insteady of _writer.DisposeAsync() hence it is complaining that Synchronous operations are disallowed.

Pleas see below code

public override ValueTask DisposeAsync()
{
	_writer.Dispose();
	return base.DisposeAsync();
}

Line no 59 in LZ4EncoderStream.cs class

Expected behavior
Expected compression to work when using WriteAsync() method

Actual behavior
Throw below exception

System.Net.Http.HttpRequestException : Error while copying content to a stream.
----> System.IO.IOException : No message provided
----> System.InvalidOperationException : Synchronous operations are disallowed. Call WriteAsync or set AllowSynchronousIO to true.

Environment

• CPU: _ [Intel 64 bit]
• OS: _ [Windows]
• .NET: _ [6]
• LZ4: _ [1.3.5]

Additional context

Thanks for reporting. Will take a look next week.

I hope it has been addressed in 1.3.6, let me know.
