I just installed Visual studio 2008 on my computer.

I created a new website. In that website, I added a master page.
But an error is displayed as given below.

The module was expected to contain an assembly manifest. (Exception from HRESULT: 0x80131018)

I could not add new items in the website even if the master page is not created.
I mean I could not add new button or label anything.

Please help me...

Thanks in advance.

Sounds like a broken installation. Maybe reinstall .NET and/or VS 2008 and remove any plug-ins.

Also see here[^].

You provided too little information to solve the problem completely, but I explained the background in my recent answer:
