Installing SharePoint 2013 Developer Tools for Visual Studio 2012

However Visual Studio 2012 does not include the SharePoint 2013 Developer Tools Preview with it.
So, to install the preview tools, you need to grab the Microsoft Web Platform Installer
Download the web platform installer, search for SharePoint and you have it there:

Not enabled Share point solutions for SP 2013

Need to download and install in the following software’s until 9^th point and for 10^th  point need to install via Microsoft Web Platform Installer

you have to install properly on the office developer tools

 Microsoft Office Developer Tools for Visual Studio 2012

otherwise you will get in the below error



Then you have to unistall and install again

Now you can create Visual webpart and deploy into SharePoint 2013

Certificate Validation errors in SharePoint 2013

I got client investigating performance issues – the Portal pages were sometimes taking a very long time to load. Page load times were inconsistent, and the browser would spend a long time “Connecting…”, before content would load on the page. Checking the event logs, we saw a frequent error message:

Error:

A certificate validation operation took 30008.7312 milliseconds
and has exceeded the execution time threshold. 
If this continues to occur, it may represent a configuration issue. 
Please see http://go.microsoft.com/fwlink/?LinkId=246987 for more details.

 I did something similar before and had to generate a cert via powershell. So I done the following in the SharePoint Management Shell:
$rootCert = (Get-SPCertificateAuthority).RootCertificate
$rootCert.Export(“Cer”) | Set-Content C:\root.cer –Encoding Byte

The Certificate file will be saved on the C drive


 Once done I went back into the certificates snap in and imported the certificate into the trusted root certificate authorities. Once done the bulk of the errors disappeared 

Then I added Host entry of the web app port number in that host file entries
