.Net Again…VS2008 touching an old project

Request for the permission of type ‘System.Web.AspNetHostingPermission, System, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089’ failed.

Don’t you just love it?

How I got here:

Fired up VS 2008 and opened up the project from a network location.


Ok, not a trusted location.  If you continue and try to run the project you will get a security issue.

Now this just seems wrong to me.  I’m on a VPN connection…

Yet I get…

[SecurityException: Request for the permission of type 'System.Web.AspNetHostingPermission, System, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.]
   System.Reflection.Assembly._GetType(String name, Boolean throwOnError, Boolean ignoreCase) +0
   System.Reflection.Assembly.GetType(String name, Boolean throwOnError, Boolean ignoreCase) +42
   System.Web.UI.Util.GetTypeFromAssemblies(ICollection assemblies, String typeName, Boolean ignoreCase) +145
   System.Web.UI.TemplateParser.GetType(String typeName, Boolean ignoreCase, Boolean throwOnError) +73
   System.Web.UI.TemplateParser.ProcessInheritsAttribute(String baseTypeName, String codeFileBaseTypeName, String src, Assembly assembly) +111
   System.Web.UI.TemplateParser.PostProcessMainDirectiveAttributes(IDictionary parseData) 



So, I copied the project to a local folder.  Tried VS again…

No change to the file but no warning message either…

No problem either.  The app fired up in VS just fine.

Now why didn’t it work?

One thing is Windows 7.  Windows 7 has trust issues!  Well, not really but the security is certainly increased.  Security state is persisted down so if you open a non-trusted location the files remain so.

Second thing… the credentials I used to access the network location through the VPN are different then the credentials I used to log on to the PC.  Again, there are certainly ways you can get around it but that’s another story.

So, will the copy fit the needs?

Well, hmmm.  …

A remote application NOT under source control can be copied down to a location where source control is used. 

The copy remains untouched until the changes are complete and tested.

A new copy can be put back up in the network location as the next rev.

Thanks to local source control, the changes are persisted.

We’re done here…

Ok, this is a quick and dirty way around a security challenge.  While perhaps not the most elegant solution it fit the bill.  Call it guerilla coding or what not, when you’re in the trenches, a simple copy paste keeps the hourly rate down.

Originally, this was a pretty darn boring post. Kinda like... Well I won't go there. Perhaps its still on the robotic side but... I could say I like music. Safe, generic and non-comittal. Or, I could say that I've been having a blast tuning up my old guitars, getting blisters on my fingers and turning the amp up past 2. Amazaing what a little overdrive and a half pressed wahwah pedal can do for a sound. Get that cool "Money for Nothin" vibe happening. I get a real kick out of reading old Sci Fi. Reading Asimov's vision about the future is really entertaining now. When he wrote much of the material, the items that were futuristic were day to day tools I used in the early part of my career. Microfiche and the like. I also remember that upstart Microsoft and MS DOS...and can you say Lotus 123? So maybe this is a little better than "I like to read and play music". My career is focused on Team Leadership and Technology. Both share the attributes of continual growth and education. Currently, I manage a team of 4 programmers as direct reports. I've been in this role since 08/2007. Prior to that, I was the team lead (on site) for integration with the customer. Customers ranged from local government to manufacturing and medical. Teams ranged in size from one to six additional team members. On the other side is technology. I've been keeping current with .net technologies focusing on C# and Sharepoint (2007/2010). Specialties Team Building and Management Technical Staff Recruiting Microsoft Visual Studio 7 through 2010 (VB.NET and C#.NET) Microsoft SQL Server 6.5-2008R2 (DTS, TSQL, SSIS, SSAS, and SSRS ) SharePoint 2010 (Office Integration, InfoPath, Site Management and planning) Windows Server 2008 R2 AD DS PowerShell Techology analysis Puchasng and working with vendors Microsoft licensing management and compliance Business Systems Analysis Traning plans Mentoring Training coordination.
