and Visual Studio 2013 Express for Windows Update 3 here.

The latter is the tool to develop Windows Store Universal Apps. In addition to the above if you install Web App Template of correct version as described here:

you should be able to create Web Apps (convert your web site to an app) as described here:

Problem
-------
In this post the following problem occured when Update 3 was applied to an existing Visual Studio 2103 Express for Windows Update 2 with Web App Template extensions installed.

1. When a new project was created there were no Web App Template
However by going to Tools | Extensions and Updates.. did show two installers available, Web_App_Template_installer versiosn 1.1 and 2.0 but they could not installed because there were only two options disable/uninstall

Solution
--------
Solution was found after interacting with the ASP.NET Forums. The suggested cure was to delete several files below in the following folder:

C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE\PrivateAssemblies

• Microsoft.VisualStudio.Web.WindowsAzure.Contracts.dll
• Microsoft.VisualStudio.Web.WindowsAzure.Explorer.dll
• Microsoft.VisualStudio.Web.Internal.Contracts.dll
• Microsoft.VisualStudio.Web.WindowsAzure.Impl.dll  (should not present, just in case
• Microsoft.VisualStudio.Web.WindowsAzure.pkgdef  (should not present, just in case)

In the present computer only two files were present:

Microsoft.VisualStudio.Web.WindowsAzure.Contracts.dll
Microsoft.VisualStudio.Web.Internal.Contracts.dll

These were moved over to a different location (just in case!) and the VS2013 was restarted, the templates appeared in the New Project window as shown:

These are the template files presently available in Visual Studio 2013 Express for Windows Update 3:
Web App Template for Universal Apps -Ver 1.2
Web-App-Template -ver 1.1

In the Tools | Extensions and Updates..., the two files mentioned previously remains with the same options disable/uninstall
