How to use ?
If we set MetaDescription and MetaKeywords either from Code behind or using Page Directive in aspx page, both will be render as “meta” tag in html code.
Let have a look, how we can set these two properties from code behind,

Now, If I run the application and check the HTML rendered content we will found the following code,
<
head>
<meta content="ASP.NET 4.0 Information" name="description" /><meta content="ASP.NET 4.0, .NET 4.0" name="keywords" /></
head>
Similarly we can also add MetaKeywords and MetaDescription Properties in Page Directive Itself.
But the HTML output will be same for both the case.
