C++/CLI Compile Error When NGraph is used in 2020.2

[at93]

Hi Everyone,

I've created  an inference wrapper class for .net. This has worked well in the past versions until 2020.2 released today. Some of the APIs have been moved to nGraph. I've modified my code to reflect the API change. When I compiled I encountered the errors below:  My question is. is std::mutex (within ngraph) not compatible with /clr ?  If so, is there a work around?

I will keep you updated on the status of this bug.

Hi Sahira,

I faced the same problem with OpenVino 2022.2.

Is there any fixing planned?

Thank you

I'm running into the same issue with upgrading a .NET wrapper to use the 2021.3 release.  Has there been any movement or a workaround on this?
