Unable to find the requested .Net Framework - Create a new p

Hi All,
I'm stuck on Sitefinity Project Manager.  I'm running on version 4.4.2117.0, Windows Server 2008 R2, SQL Server 2008 (10.50.1600.1) 64 bits. 

I defined a new project and when I click on "browse" button, the project initialization is launched, then I entered Database Information along with credentials, and when i click "Next" then I got an exception (showed below).

What .Net Version is sitefinity project waiting on server?  So far, I have a Sitefinity Project up and running on version 4..4.2117.0, so that's makes me feel .Net Framework is installed.

Any ideas?

Hello Carlos,

Is your other project on the same server as the one that you're trying to create. Also, is your database on the same SQL? Have you modified your server somehow or your server configurations. Have you registered a new data provider? The one that Sitefinity uses in System.Data.SqlClient. You get the error message, because Sitefinity expects .Net 4.0 Framework, but since you have another working project, that means  you have this version installed already. The problems must be in the configuration changes made after installation. Have you by change modified the machine.config? Try restarting and creating a new project and let us know what happens.

Hi Jen,
Thanks for your reply.  I double check our server and .net framework 4.0 is installed and as you mentioned it shouldn't be an issue since I've a sitefinity project up and running on same server.  I deleted and restarted a new project from scratch, and I get the startup page from where one can enter the SQL server name and credentials, but as soon as I click on next button the page end up with this .Net Provider issue, as you notice I'm not changing config files and machine.config file has never changed.

Please let me know what information do you want me to attach for revision.
-Carlos.

Hello,

The problem is caused by the general .NET configurations. Can you try creating the project on another server and see if the problem reproduces?

Hi Jen,
Same issue reproduced on a different server.  What .Net configuration do you want me to check?

Hello Carlos,

The problem seems really unusual. Since we can't reproduce it here for now, we will need some time to investigate what might be causing it.

Hello Carlos,

This seems to be a problem with Visual Studio and there has been a lot of people with the same issue on the internet. I have prepared a google search for your convenience. I would suggest to start with this one because it seems that this is the most common solution. I will try and elaborate on it.

Go to \Windows\Microsoft.net\Framework\vXXXX\Config and locate the machine.config file. Go through it and locate the following lines:

Same problem after upgrading to Telerik Data Access Q2 2014. This fixe works.
