Do you see anything like this in the C/C++ extension logs? You might need to increase the logging level (C_Cpp.loggingLevel):
cpptools/queryTranslationUnitSource: C:\Projects\Project\main.c (id: 3)
Custom configurations received:
uri: ...
config: { ...
If so, does the uri and configuration look correct? The configuration you get for main.c is the default intellisense config, which means that the C/C++ extension either isn't receiving the custom configuration, or is ignoring it.

For the file which is not part of the project i do receive a custom configuration.

Just to clarify some things:
Do you get the incorrect configuration for all files in the project, if there are multiple?
Does this occur for all projects you open or just this one?
There is an unlikely case where an error could occur but not be logged, and that seems to be the only possible explanation here. To confirm it, I would need to add some more logging in the next extension update, and then you can check the logs again after the update is released. I'm not sure exactly when that will be, but it should be fairly soon.

Yes, i get the incorrect configuration for all files in the project and this also occurs for all projects.

Okay, so i dug a bit more into this. Seems like the C++ extension has a 2 second timeout on providing it the configuration and this extension needs more than this (~2-4s) on my machine / for my project. Any idea how to speed this up?

Thanks, that explains a lot. In order to generate the configuration for a file, we run the compiler with some special flags that output include paths and defines. This parses the entire file, so if the file is large or the cpu is busy, it's not impossible for this to take a few seconds.
I'll see if we can speed it up in any way, but I also want to ask the C/C++ extension developers if they could increase the timeout window; 2 seconds seems like a really short timeout.

Increasing the timeout has apparently been asked about before:
microsoft/vscode-cpptools#2229
I've fixed the problem by checking if we time out, and asking the C++ extension to resend the reqeust in that case.
