Use the amazing text-to-HTML tool Markdown to create HTML in Visual Studio.
You can create a markdown file directly in Visual Studio and this tool will output the generated HTML as a file within the project.
I am currently using it to output a partial view for ASP.NET MVC3 for a help/FAQ page.
It allows me to write the page using Markdown and have the generated file used as a partial view without me having to copy and paste from a markdown converter to Visual Studio.
So the tool can infer what file extension you would like to create you should use the following filename pattern:
filename.[required_extension].md or filename.[required_extension].markdown
examples:
test1.html.md
test1.cshtml.md
produces:
test1.html
test1.cshtml
Set the "CustomTool" property on each of your markdown files to "Markdown".
The HTML output will now be automatically created every time you save the markdown source file.
