warnings from visual studio code analysis
visual studio now integrates clang-tidy, here's the output of a run on the calc-native project. Some of these might be worth cleaning up. I didn't see any that I though were dormant bugs though.

2>Done building project "CalcNative.vcxproj".
vcpkg
Is there vcpkg for this library ?
Failed to send request: broken promise
Just testing with the included CalcNative example.
Running it normally works but trying to simulate a request that would take longer to process on the server side (In this case adding a sleep of 10 seconds) causes the client to fail with "Failed to send request: broken promise".
Is there some sort of timeout setting or is this an issue?
[native, managed] Add native to/from managed communication test
Test for native to/from managed communication is missing.
Change to code that doesn't use boost
I don't know if this is an unreasonable demand.
While reviewing the use of this IPC library, I was asked if boost was absolutely necessary.
At this point, most of them can be replaced by standards such as c++17.
The internal code is well written, but the usability is not the best.
How do you think?
[managed] Add reverse connection support
Currently the ClientAcceptor, ServerConnector, AcceptClient and ConnectServer functionality is missing in managed wrapper.
[managed] Expose ChannelSettings
Currently ChannelSettings is not available in managed wrapper.
[native] Make the native part cross-platform
There are several components that have Windows-specific implementation (e.g. thread pool, named events) which can be expanded with corresponding cross-platform versions.

Solution is not working in VS 2022
Can anybody confirm that the solution is working in VS2022.
I get errors like:
Error C2440 "return": "initializer list" can not be converted into "IPC::SharedMemory::Allocator" CalcNative ...\IPC-master\IPC-master\Inc\IPC\SharedMemory.h 82
[native] Rename NullTimeoutFactory to InfiniteTimeoutFactory
[managed] Add other containers
Currently only IVector is available. Would be good to add other containers such as list, set, map etc.
[native, managed] Add test with separate process
Currently all the tests are running within the same process. Would be good to have some that use separate ones.
[native, managed] Add permissions support
Currently default security settings are used. It would be good to support permissions.
[general] Documentation is missing
There should be at least some explanation of key concepts and workflow before lookinng into unit tests makes sense.
[general] Add support for streaming
[native] Explicitly use duration::zero() instead of {}
Using std::chrono::duration{} may not produce the same value as std::chrono::duration::zero() if duration_values is specialized.
could this send message from x86 program to x64 program
I build IPC run as server in x64 and run as client in x86. It seems do not work. And just get
Press Ctrl+C to exit. Connecting to ipc://calc
Can you provide examples of C++ and C#?
Can you provide examples of C++ and C#?The test is too simpler，i don't know how to use it
Does this project support x86 platform on windows?
Does this project support x86 platform on windows?
IPC.Bond - managed version - broken in VC2019
Typo in Product Description?
Should "...is available which allows interaction with C++ as well." be instead "is available which allows interaction with C# as well."?
