I need to visualize complex business logic on a single ASP.NET page that has over thousands of lines code so I decided to give Visual Studio's own "Code Map" feature a shot, which is described here: http://msdn.microsoft.com/en-us/library/jj739835.aspx
The tool looks like this:
I tried with VB.NET and C# (including MVC) projects and it was working very well... or that's what I thought, until I tried to use code map tool on an ASP.NET project.
Instead I got this helpful window:
I couldn't find any documentation that says "it's not supported" so I guess I'm doing something wrong? Is there any way to get this tool work, manually trying to add did not help either. I'm open to suggestions.
It appears you're using a File System Web Site Project. These have nebulous support in Visual Studio 2012 and later. I say "nebulous" because I haven't found anything that explicitly states they're deprecated, but the documentation for them is only provided for Visual Studio 2005, 2008 and 2010.
If you need Code Map support for your project, consider converting it to a Web Application.
