HTML source validation in Visual web developer 2005

To set these validations



Go to tools menu-> Options menu item in VS or Visual Web Developer.
Select the Text Editor->Html->Validation tree option in the left-hand side of the options window,

Note: HTML validation errors will not block a web application from compiling / running.
