Helix Solution not working.

Hi,

I hadn't updated my Helix for while, so I started fresh with TortoiseHg - I followed the instructions here :

https://helixtoolkit.codeplex.com/wikipage?title=Obtain%20and%20build%20the%20code&referringTitle=Documentation

But when I try to open HelixToolkit.Wpf.sln it throws this error :

Unsupported
This version of Visual Studio is unable to open the following projects. The project types may not be installed or this version of Visual Studio may not support them.
For more information on enabling these project types or otherwise migrating your assets, please see the details in the "Migration Report" displayed after clicking OK
HelixToolkit, "C:\Users\Roger\Documents\Visual Studio 2013\Projects\HELIX\Source\HelixToolkit\HelixToolkit.csproj"

In the following migration report I get this :

HelixToolkit\HelixToolkit.csproj: The application which this project type is based on was not found. Please try this link for further information: http://go.microsoft.com/fwlink/?LinkID=299083&projecttype=786C830F-07A1-408B-BD7F-6EE04809D6DB

The rest of the files appear to be migrated okay as they all have ticks.

Now I cannot work on my project sadly. Could someone please help ?

Many thanks,

Rog.

P.S. I am using Visual Studio 2013 Express.

Any thoughts ?

The HelixToolkit.csproj project is a portable class library.
I think you have two options:

1. You can change this to a class library to compile with VS Express.
2. You can also remove the project and references in the solution, the project is not yet in use. This option will not work when code is added to that project
