Hello,ASP.NET World

Code enclosed by <% ... %> is just executed, while expressions that include an equal sign, <%= ... %>, are evaluated and the result is emitted as content. Therefore <%="Hello World" %> renders the same thing as the C# code <% Response.Write("Hello World"); %> .

Note: For languages that use marks to end or separate statements (for example, the semicolon (;) in C#), it is important to place those marks correctly depending on how your code should be rendered.

C# code
<% Response.Write("Hello World"); %>	A semicolon is necessary to end the statement.
<%="Hello World"; %>	Wrong: Would result in "Response.Write("Hello World";);".
<%="Hello World" %>	A semicolon is not necessary.
