Now when I open webiste in Web Developer, and browse with Internet it wont open. And also in Web Developer getting on each website huge Warnings.
1. D:\Webisite\details.aspx: Asp.net runtime error: Could not load file or assembly ''Xheo.licensing Version= 2,0,3300,0.
2. This name contains uppercase characters, which is not allowed
3. Unrecognized tag prefix or device filter 'asp'.

The Uppercase warnings look like the site was first built using the older HTML standards which allow upper and lower case in the tag names and attributes. Since moving over the it looks as if you are using the XHTML 1.0 standard which does not allow upper case in the tags.

<!-- Valid HTML Code, Not valid for XHTML --->
<DIV CLASS="class1">Inside Div 1 </DIV>

<!-- Valid XHTML Code --->
<div class="class1">Inside Div 1 </div>

Now these are only warnigs so your page should still show. But it is best to fix them and to adhere to the XHTML standards if that is what you are using.

and thank you for reply.

I have install all IIS features.
I have also install all VS tools from installation, and almost all warnings has gone, except one has left

I'm suprised that on the web there is no solution for this issue. I have checked a lot posts.

Any idea?

Here is error when try to open my page:
