ASP.NET MVC Publish to sub directory in ASP.NET WebForms gives Error 404

Question

I have ASP.NET WebForms project in root directory working perfectly.

But now I have created my new project ASP.NET MVC and uploaded to mysite.com/subdirectory but I don't have access, it gives 404 - File or directory not found.

Here is my WebForms web.config in root directory:

Answer 1

Although I haven't tried, I presume that the same Umbraco instance cannot handle both WebForms and MVC websites.

Here is an answer to the similar question with mixing MVC and WebForms in the same website. Hope this gives you a better insight in the problem.
