I have been struggling with getting vmicro to work. I have to admit, I am a relatively new to Visual Studio user also, so the issues im experiencing may also have to do with my Visual Studio setup.

The issue I have is that whenever I start a new project, without adding a single line of code, i immediately get the below list of errors:

invalid second parameter type ("unsigned int") for literal operator; must be size_t in file mbed_retarget.h
more than one instance of overloaded function "fstat" has 'C' linkage in file mbed_retarget.h
more than one instance of overloaded function "stat" has 'C' linkage in file basic_string.h
invalid second parameter type ("unsigned int") for literal operator; must be size_t  in file basic_string.h (same message 3x)
first parameter of allocation function must be of type 'size_t' in file new (same message 6x)

Googling this has yielded no results.

Can anyone point me in the right direction, please?

Attached the full build report.

Thank you

Thank you, Simon!

That did indeed reduce the errors, by a lot, all except Error E0338 "more than one instance of overloaded function "fstat" has 'C' linkage" in File mbed_retarget.h on line 746 and 750. 

Only changed ARM64 to ARM as per your suggestion above.

Any suggestions to remove this error also?

Thanks for your help!

Currently it is simplest to just suppress this error code from appearing in Intellisense.

If you download the attached file, and place it in YourProjectFolder\_vm\vs-intellisense-fix-pre.h, and then reopen your project it should prevent the error from appearing.

Glad to help, we have updated the documentation about Extending Intellisense below with this example:
