	Using println(F(" No Data")) is reporting that it Cannot resolve symbol '__progmem__' The program compile, uploads, and executes. How can I eliminate this error?

	Does the name of the project show in the solution explorer suffixed by the text "(Arduino)"? If not then click the vMicro>Convert button to use the newer intellisense engine. Otherwise, please post the information that we have requested.

	What is the full line of code? It is possible the __progmem__ source is not available to intellisense. In that case we can explain how to add an intellisense definition.

	Thanks for the detail. Can you try closing the solution and deleting the ".vs" folder from the solution, then reopening it again? If this still shows the error could you attach or email us your VCXPROJ file, or if possible the entire project for us to investigate further?

	Thanks for the project. Can you try running Build > Clean Solution and then building the project again? Also, do you get the same error when using the Flash String Helper in a Serial.println(F("Something")); statement?

	It appears to be a ReSharper problem. When I suspend ReSharper the red squiggles go away.

	Thanks for the update. Out of interest, does the below .editorconfig help to avoid these issues showing when using both Re-sharper and Visual Micro? https://stackoverflow.com/a/70869752
