I'm new to visual micro, but have been using visual studio for a while and have lots of PIC experience.  I've got an Adafruit Metro M0 (similar to Arduino Zero) that I'm using in my latest project.  On a new project I'm getting E1696 cannot open arm_compat.h, followed by a host of other errors because of the missing include file.  This #include is in cmsis_armclang.h.  I can compile and upload basic code using I/O and serial communications, but calling __disable_irq() causes a failure.

Can anyone offer some insight into where arm_compat.h should be (I've searched my computer and its nowhere to be found) or a workaround for the missing intrinsics which appear to be declared in it?

Here is the information requested.  I checked and you were right, it's an intellisense error.  I am able to compile and upload the code with __disable_irq() and it's functional.  I had a stupid typo in my code that I fixed.  intellisense still generates and error for "noInterrupts()" and "__disable_irq()" but it compiles and runs fine.  Thank you for your help.
