or i think your talking about this:
Create SharePoint Project
1.Open Visual Studio 2010
2.Click File -> New -> Project
3.Select “Empty SharePoint Project” under SharePoint -> 2010 category.
4.Enter Name for the project e.g. SampleWebTemplate.
5.Click OK.
6.Select “Deploy as a sandboxed solution” in next window.
7.Ensure local site is your targeted site.
8.Click “Finish“
Create Element with Feature
1.Right click on project (i.e. SampleWebTemplate) points to “Add” and click “New Item“
2.Select “Empty Element” under SharePoint -> 2010 category and name it to SWTSite (Sample Web Template Site)
3.Above step will create a SharePoint element (Elements.xml) with a feature associated with it.
4.Newly created feature name is “Feature1”, we must rename it and name it same as Element name (i.e. SWTSite) otherwise we must change
DeploymentLocation in onet.xml.
5.To rename feature, Click on feature1 and Press F2.
6.Change feature name from Feature1 to “SWTSite”
7.Open “Elements.xml” Now we need to add few tags in it as shown below.
8.Add element “WebTemplate”. WebTemplate element has four mandatory attributes, Name (Internal name of site template), BaseTemplateID,
BaseTemplateName and BaseConfigurationID are used to define base
template on which new template is based on.
9.Title and DisplayCategory are used for ease. DisplayCategory is tab name under which template will be visible.
10.Now “Elements.xml” will look like this.
<?xml version=“1.0“ encoding=“utf-8“?>
<Elements xmlns=“http://schemas.microsoft.com/sharepoint/“>
<WebTemplate Name=“SWTSite“
Title=“Sample Web Template Site“
BaseTemplateID=“1“
BaseTemplateName=“STS“
BaseConfigurationID=“0“
DisplayCategory=“SWT sites“ />
</Elements>
11.New Web Template is based on an existing web template (which is STS template).
12.Now we need to copy template’s files and modify them to change whatever in the template. In this example we will not change anything
but just re-use the template as is.
13.Open “C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\TEMPLATE\SiteTemplates\sts” folder
14.Copy both “default.aspx” and “defaultdws.aspx” into your project folder.
15.Copy “ONET.xml” from “sts\xml” folder to your project folder also.
16.Right click on Element(i.e. SWTSite) points to “Add” and click “Existing Item“
17.Select all three files that you copied before (default.aspx, defaultdws.aspx and onet.xml) and press “Add”
18.Make some changes in feature we must set feature Scope to Farm to be able to do this.
19.Right-click on SWTSite feature and click “View Designer”
20.Change Scope to “Farm”
21.Change Title/Add description of the feature if you would like to, this will appear under farm features.
22.As an example change title to “SWTSite Feature” and add description “This feature will add new web template based on STS
template.”
23.Important! Make sure three files (default.aspx, defaultdws.aspx and onet.xml) that we added before are also included in deployment.
24.To ensure this, Click on the file one by one and select Development Type as “ElementFile” whereas Elements.xml will be of type
“ElementManifest”
25.Make sure you mark Sandboxed Solution to FALSE in project properties because sandboxed solution cannot be deployed at Farm
level.
26.Deploy your solution. If successfully deployed go ahead otherwise, look through all steps above if you missed something. If you
encountered with something un-addressed, please write it in comments
so I can update the post and make it more useful for others.
27.Create new site collection and apply new template.
