Access denied by caller on call of Cally

I got this issue while i was trying to access parent pages tags into child.

scenario : Both pages exist in different folder. Folder may be readonly.

so if we will try to get properties of parent page that exists in differnt folder then we might need to check readonly access of file , some its on page level or folder level.
JUST by removing the readonly access of file/folder we will be able to remove the error.

Exception from HRESULT: 0x80070057 (E_INVALIDARG))

This is very comman issue while we try to run asp.net application we get following error

Could not load file or assembly 'ProjectName' or one of its dependencies. The parameter is incorrect. (Exception from HRESULT: 0x80070057 (E_INVALIDARG))

So basic reason of this issue is that we havent cleaned the project or temprory files

Do 2 things to remove this issue
1. Clean your project and rebuild the project.
2. After following step 1 if you are still having same issue. check target framework of project and go to following location and delete all files

C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files

In My case, project was in .net framework 4.0 so i deleted temporary asp.net files from its child folder. If your project is targeting to some other project delete  Temporary ASP.NET Files from its child folders.
