Hi Aaron. I tried rebuilding Pulse with the new ECMO simulation features using Visual Studio, but I’m running into problems that may be due to my version of Visual Studio (2026).
The following error message has come up from trying to make the InnerBuild. A screenshot is below.
Googling and AI are telling me that this is due to the VS compatibility issue. Any suggestions on how to fix? Thank you!

Yes, the latest updated visual studio complier removed support for their C++ stdext extension
I have this fixed (via upgrading our build to use C++20), and have just merged it into the ECMO\_Updates branch. So pull the latest and start with a clean build directory… you need to do a full rebuild.
