I lost a intelisence and code highlighting vs 2015

[deltics (Jolyon Direnko-Smith)]

This can be a general problem with Visual Studio, not specific to Elements.

I had a similar problem and found a solution which I describe in this thread:

Syntax Highlighting and other Editor function (Code/Class Completion, Auto Indent etc) completely broken in VS2015 [Community Ed] (Elements 8.1.85.1801)

As per subject. I have absolutely no syntax highlighting, code completion (suggestions), class completion, auto formatting (indentation/alignment) in any Elements file types (Oxygene, C# or Silver). “Built in” Visual Studio languages (C#) are fine, as are the XAML files even in Elements projects. Same Elements version in VS2013 seems 100% AOK in these respects. Is this a known problem ? Will there be a fix soon ? Obviously I can continue using VS2013 for a while but would prefer to move up…

Failing that, there are other potential solutions described in this article:
