OleViewDotNet.Main fails to build with Visual Studio 2015

[u0m3]

I came across some errors when compiling OleViewDotNet.Main from main branch commit e454c15bcb27204942f5c8b79f6f282e18c9e825.

Apparently my C# version does not like

int.TryParse(parts[0], out int address)

or the likes. Nor does it like

            if (dict is SortedDictionary<S, T> sorted_dict)
            {
                return sorted_dict.Comparer;
            }

complaining _sorteddict does not exist in this context. I'm using Visual Studio 2015 Version 14.0.25431.01 Update 3. Any ideas on what went wrong?

i don't know this problem, but if you just want to use this not learn it's source code, you can download the release version, just in the main page 3 releases

Basically I'm slowly moving new code to using C# 7 language features which are not supported on VS2015 and will require VS2017. As binlmmhc points out you should be able to download the source code for v1.4 from https://github.com/tyranid/oleviewdotnet/releases/tag/v1.4 (or checkout the tag from the repo) and that should still build in VS2015.
