Could not load file or assembly ‘BasicFrame.WebControls.BasicDatePicker’ or one of its dependencies. An attempt was made to load a program with an incorrect format.

Cause:
For me this error came when i tried to install my ASP.net 2.0 website built on 32 bit on a server which was 64 bit.

Solution:
Open your IIS Manager (in my case it was 7.5) and then right click on application pool to have advance settings and make enable 32 bit application to TRUE.

Failed to access IIS metabase

You can get this kind of error while browsing a ASP.net website.This error usually occurs when one’s computer has .net framework installed before IIS is installed. So when you stage the website,this error seems to popup. I was debugging someelse’s work and came across this error. It was rectified by installing again the .net framework. This can be done by writing this command on the command prompt

%windir%\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis.exe -i

Then try to browse your website and probably/hopefully the error will be gone with wind
Happy Browsing
