These projects are either not supported or need project behavior impacting to open this version of Visual Studio

Question

Hi All, 

I am exploring a projects that are developed in Visual Studio 2010 Professional to Visual Studio 2013 Express edition. 
I am getting below errors: 

I have tried different blogs:

1.  Cannot be opened because its project type is not supported by this version of the visual studio, 
   Blog 1 and Blog 2. 
   devenv.exe /resetskippkgs did not work for me. 
   
2. Create a blank solution and then add existing VS 2010 projects.  
   Did not work.

Any suggestions would be highly appreciated!

Thanks in advance.

Answer 1

What kind of project cannot be opened? Show a project name including extension.

.NET projects in .csproj extensions are giving error as mentioned in screenshot.

Answer 3

Are you using the appropriate version “Visual Studio Express 2013 for Desktop” or “Visual Studio Express 2013 for Web” and did you consider Visual Studio Community 2015” too?

Also note that Express is simpler than Professional and such conversion is not always possible.

Answer 4

Hi Viorel

All the projects are web related so I downloaded the Visual Studio Community 2015 (around 9 GB) but it gave the same error as above. 

Then I downloaded Visual Studio Community 2013 with Update 5 as shown below but again get same results. 

Q: How could I upgrade/migrate VS 2010 professional .NET projects (.csproj files) to Visual Studio 2013 Express for web?  Please advice.

Answer 5

Hi Sandy,

Please try the following ways at first:

1. Right click on the solution file in Solution explorer window and select reload ploject this will convert the application to vs 2013

2. Create a new empty solution in VS2013, then open separate project files which created in VS2010 then try it again.

In addition, please take a look at the following document about VS2013 Compatibility.

VS2013 update5 generally support to open the projects which create in VS2010 SP1. But not for all type projects.

I suggest you could create a same type project in your VS2013 to check whether support this kind of project.

May be the project type you created in VS2010 is not support to be opened in VS2013 by default.

Also since your project was created in VS2010 Pro. And if you want to open in VS2013. May be you need to use a VS2013 Pro version of VS to test it.

Or if possible. You could share a simple to us and we will help to troubleshoot it in our sides using VS2013 Pro.
