Error adding new project to solution in Visual Studio 2010 Path Length

Question

I am a bit baffled. I am creating a new solutions with some namespaces that are consistent with the framework I am working at the moment.

When adding a new project the total chars is 150 way below 255.

Why do I get this error when adding a project?

"The length of the full path for the solution ,project or item you are creating exceeds the maximum length allowed by the system.You must reduce the length of the name or the location"

What is the rule? How many chars I am really allowed?

thanks

EDIT

Just found a link which says that the path is calculated : see link http://social.msdn.microsoft.com/forums/en-US/csharpide/thread/d614d0ba-eea2-444b-9be8-7fe4fb85a226/

  Path length + 1 (separator) +    Solution name length + 1 (separator) +    Project name length + 1 (separator) +    Project name length +    80 (Reserved space) 

Answer 1

I found once my project is created, I can then change my project to a longer name. Project name change doesn't seems to have this number of characters limitation.

-- An update on 7/Mar/2018 -- In Windows 10, you can actually disable the Max Path Length limitation.

This is just a variation on @Kelvin's answer, but you can create a new project in a location with a short path, e.g., c:\temp. Then move the project folder tree into the framework you're working on.
