“The TEXT rule is only used for descriptive field contents and values that are not intended to be interpreted by the message

Established leaders (in blue in the chart and including Java, C#, and JavaScript) which are "common in paying organisations and show a high demand globally". Followers (in green) such as PHP, Python, and Ruby were found to "pay on average the same salaries, although their is 50% less demand for them". Finally there are a group referred to as Niche (orange) which "show very low demand and salaries almost 60% lower". 

Improved the MSBuild selection logic. The standalone instance inside OmniSharp is now preferred over VS2017, with VS2019 given the highest priority. This ensures that .NET Core 3.0 works correctly. It is also possible manually provide an MSBuild path using OmniSharp configuration, which is then always selected. (omnisharp-roslyn#1541, PR: omnisharp-roslyn#1545)
