Can't view project using Visual Studio 20082/4/2008 6:28:51 PM

Hi,

I've recently installed Visual Studio 2008 and using VS I've opened a "website" folder on my computer so I can make some amends.

The location of the folder on my computer is P:\Castle Point Business Forum\Website\cpbusinessforum.co.uk\

But I've noticed that there is a problem viewing files in a browser using VS (e.g. it's own variation of localhost), where by all my fully functioning websites display the below error message. Can anyone please advise what might be causing this problem and how to resolve it. There is nothing special happening in my application, it doesn't use a database and is a straight forward simple ASP.NET 3.5 project?

Many thanks.

Try to set the trust level

<trust level="Full" originUrl="" />

It looks like P: is a network drive. Network locations are not considered trusted in .NET. Did the project work before? Generally you can adjust security policy using caspol.exe utility.

Thanks

Hi Hosam,

This didn't work I'm afraid.

I tried what you suggested but the same error message appeared.

The below is the part of my web.config which has been updated (maybe I added the trust level to wrong section - maybe it should sit within a <location><system.web> tag rather than within the main <system.web>...

....<connectionStrings/>

<system.web>
      <trust level="Full" originUrl="" />

      <compilation debug="false">

      <assemblies>....

Hi Mikhail,

Thanks for the reply, I'll see if I can download caspol.exe and change the trust settings.

You are correct that this is a network drive, as the hundreds of projects I have wouldn't all fit on my PC's hard drive so I have to resort to storing my projects once completed on a network drive at my office and it's only now that I've had to go back to update a project that I thought I would just run VS and point to the relevant folder (saves me creating a new virtual directory in IIS and copying the folder/files over to my PC etc etc).

.NET:
I'll see if I can download caspol.exe
 

CASPPOL.EXE comes with the .NET install. It is in %WinDir%\Microsoft.NET\Framework\v2.0.50727\

For development purposes you should be using a command prompt with the frame folder included in its PATH. The VS Command Prompt shortcut on the start menu will be correctly set up.
