Masking IWebHostEnvironment in .NET Core 2.x for operation like 3.x

IWebHostingEnvironment is not available in .NET Core 2.x, but in 3.x it's the recommended way to access the host environment with threat of IHostingEnvironment being removed in the future. This can be a problem in libraries that need to run both on 2.x and 3.x.

The following tries to mask the differences in a multi-targeted .NET Core project by creating a custom IWebHostEnvironment implementations that picks up values from IHostingEnvironment in 2.x.

using Microsoft.Extensions.FileProviders;

namespace Microsoft.AspNetCore.Hosting

UrlEncoding on local Urls producing double encoded Uri.AbsoluteUri values
View AbsoluteUriUrlEncoding.cs
void Main()
var part1 = new Uri("C:\\temp\\"); // double encodes when combining parts
var part2 = "assets/Image%20File.jpg";
var uri = new Uri(part1, part2);
uri.ToString().Dump(); // still encoded and shouldn't be

You can do simple date formatting with a library by using the Intl.DateTimeFormat JavaScript class.

MDN for DateTimeFormat

alert( formatDate(new Date()));
// Apr 11, 2019, 1:10:40 PM

function formatDate(date, locale) {

Markdown Monster Mermaid Sample


Mermaid is a JavaScript based parsing engine that allows you to embed blocks of graph markup into a page. Markdown Monster supports two different approaches using either code block or HTML tag syntax to embed the mermaid blocks.

@icon-warning Internal Preview Limitations

Note the MM internal preview can't properly display or refresh all chart types, but you can preview in your system browser via Shift-F12 to see proper representation.

Sequence Diagram

You can use a mermaid code block:

View XmlElementsAndAttributes.cs
void Main()
var doc = new XmlDocument();
doc.LoadXml("<d><t>This is &amp; a \"test\" and a 'tested' test</t></d>");
var node = doc.CreateElement("d2");
node.InnerText = "this & that <doc> and \"test\" and 'tested'";
var attr = doc.CreateAttribute("note","this & that <doc> and \"test\" and 'tested'");
View TestDynamic.prg
DO wwDynamic
DO wwJsonSerializer
loCust = CREATEOBJECT("TestClass")
loItem = CREATEOBJECT("wwDynamic",loCust)
*loItem = CREATEOBJECT("wwDynamic")
