Minidumper: cli to generate minidump

This cli tool is able to generate minidump of living app in three mode: full, minimal and heap. heap is really interesting because:

“dumps generated by the heap mode can be 5x or 10x smaller than full memory dumps, but will still allow complete investigation of many .NET issues by tools like Visual Studio and WinDbg (SOS)”

goldshtn/minidumper: Write minidumps of .NET processes with full memory, only CLR heaps, or no memory at all

Moreover, mini dump generation is located into an external library: DumpWriter. This library can be integrated into any program to add mini dump generation capability.

Generating a minidump is technically easy. You call MiniDumpWriteDump with a MINIDUMP_TYPE parameter to choose wich memory ranges to gather  or use a CallbackParam to manually filter memory ranges. But choosing the right one is a complicated process. Other posts are related on how memory ranges are choosen to be saved in heap mode :

How to export a C# enum:

public enum AssetStatusEnum

        var values = Enum.GetValues(typeof(T)).Cast<int>();
        var enumDictionary = values.ToDictionary(value => Enum.GetName(typeof(T), value));
        return new MvcHtmlString(JsonConvert.SerializeObject(enumDictionary));

and using it like this:

    var assetStatusEnum = @(Html.EnumToString())
