Arduino syntax not recognised in Visual Studio (Read 3717 times)

	Hi, I'm using Arduino ide 1.7.11 and Visual Studio 2015 on Windows 10 OS. After installing Visual Micro plugin for Visual Studio I tried to open a new project but Arduino commands are not recognised (all commands are underlined as errors). So I tried to open an existing example. When doing this, Visual Studio asks to be restarted with higher privileges. After restart the sketch opens correctly in the editor, but all Arduino commands are underlined as errors (see attached figure). The sketch is not compiled and all included header files (.h) are not found. Can you provide any help for identifying the problem? I also tried to uninstall and reinstall the plug-in several times but always got the same result. Thank you.

	Hi, The name of the project in the solution explorer should be "Blink" not "Sketch". Please rename from Sketch to Blink We will investigate how you ended up with an incorrect project name. The project name, folder name and an .ino name must match otherwise visual micro goes to sleep

	note: The cause of the project name reverting to "sketch" is click cancel when prompted to save the project as it closes. In the next release of visual micro the project is auto saved immediately after creation so that this issue should not be possible to repeat. Ensuring the project name is the same as the .ino and containing folder is how visual micro knows it is working with an Arduino variety of a C++ project. Thanks for the report. There is a link to the next release at the top of this post if you want to try it.
