Thanks! Could you send a pull request please?
> Using THttpTransport using interleaved asynchronous calls may throw exception
> -----------------------------------------------------------------------------

> Key: THRIFT-5830
> URL: https://issues.apache.org/jira/browse/THRIFT-5830
> Project: Thrift
> Issue Type: Bug
> Components: netstd - Library
> Affects Versions: 0.21.0
> Environment: See this PR to remove interleaved asynchronous calls to
> work-around the issue.
> [fix(csharp/src/Drivers/Apache): remove interleaved async look-ahead code by
> birschick-bq · Pull Request #2273 ·
> apache/arrow-adbc|https://github.com/apache/arrow-adbc/pull/2273]
> Reporter: Bruce Irschick
> Priority: Major
>
> When using the THttpTransport, interleaved asynchronous calls can cause the
> following exception:
> {code:java}
> System.AggregateException : One or more errors occurred. (Couldn't connect to
> server: System.Net.Http.HttpRequestException: Error while copying content to
> a stream.
> ---> System.ObjectDisposedException: Cannot access a closed Stream.{code}
>
> Essentially, the *THttpTransport._outputStream* can get disposed while
> another asynchronous call is running.
> This is due to allocating the _outputStream at the class level. The stream
> should be allocated on a call-by-call basis.
