Due to a bug in RestSharp since Version 111.3, every version of Influxdb-client-csharp after the change from July 23, 2024, can no longer be used in a project that has to include a C++/CLI part as well.
restsharp/RestSharp#2233
Maybe it is finally an issue large enough to move away from RestSharp.

Steps to reproduce:
List the minimal actions needed to reproduce the behavior.

1. Have an older project with C++/CLI, using InfluxDb-Client-CSharp 4.16.0 or older
2. Upgrade to current InfluxDb-Client-CSharp and try to compile

Expected behavior:
Compile without error

Actual behavior:
Compiling results in unresolvable error:
error C2870: 'RestSharp': a namespace definition must appear either at file scope or immediately within another namespace definition (compiling source file 'Stdafx.cpp')

Specifications:

• Client Version: 4.18.0
• InfluxDB Version: Irrelevant
• Platform: Windows 10@64, Windows11@64
