Going by the image, it would appear you are not actually having this issue. Intellisense will often leave previous compilation errors hanging around until you attempt another compilation - this is most notable in your image because the blue line indicating en error is off and does not cover the entire line. Always build or rebuild your code before assuming an error is still occurring.
