NUnit constraints broke my R#
After writing some NUnit tests with the Assert.That constriant syntax my code file was looking a bit messy so I ran R# 'cleanup' and it threw "JetBrains.Util.LoggerException: Cannot create IReferenceExpresion for 'Is' ". After that right click was kept throwing this error and to get around it I had to unload and reload the R# plugin. Not sure if it's VB and the need the escape Is as a reserved keyword but R# was struggling.
