Security error in ASP NET shared account

Question

These lines cause a security exception in a godaddy account. Any suggestions how to rewrite to get this to work?

File.Delete(PropsFileName);     // Clean up

TextWriter tw = new StreamWriter(PropsFileName);    // Create & open the file
tw.WriteLine(DateTime.Now);     // Write the date for reference
tw.WriteLine(TokenLine);        // Write the BinarySecurityToken
tw.WriteLine(ConvIdLine);       // Write the ConversationId
tw.WriteLine(ipccLine);     // Write the IPCC
tw.Close();

Thanks!

The information is being written to session.properties variable in the temp directory.

GoDaddy is set up to run under Medium trust, to simulate this on localhost add the following to your web.config:

<system.web>
    <trust level="Medium" />
</system.web>

Something you can try to fix the issues is to add the following to your AssemblyInfo.cs under Project > Properties in solution explorer

[assembly: AllowPartiallyTrustedCallers]

Also here is an article that may or may not help you out and/or give you insight regarding a similar situation with NHibernate: NHibernate in a Medium Trust Environment

You should give NTFS permissions to the user running your ASP.NET app. Your hosting control panel probably supports assigning NTFS permissions to the folder.
