VS2012 Development Server Settings

[Lotok]

I have a couple of issues with the VS2012 development server. It seems to show as .NET 2, when the application I am writing is .NET 3.5. Now i know 3.5 is an addon to 2 however pretty sure it should show as 3.5.
The other problem is application permissions. I am building an intranet tool for our helpdesk which queries AD. To do so I need to use the HostingEnvironment.Impersonate method. On IIS this works no problem, but on the development environment i get the below error which seems like it is ignoring the security level in web.config.

It just makes debugging a pain in the behind as when I step into pages with the custom control I get these errors. To test I need to load onto IIS. Any ideas on how to resolve this one?


Cheers

I don't know whether it will in this case but I would suggest installing IIS Express and using that for development as it overcomes some of the limitations of the inbuilt development server.

I enabled IIS components on my Development Machine (Win 7 Pro 64x)
Set up the application pool & default directory
Checked on browser and IIS holding page shows.

Yet, cannot debug to it. If I move debugging server to IIS7
I get: Unable to start debugging on web server. The web server could not find the requested resource.

MSDN helpfully says this is a generic error and could be caused by many things...great!

Cheers for idea of moving away from VS development server though, pretty sure getting this working is worth the effort to get passed the quirks.

Are you using IIS Express as a development server from within VS?

In Visual Studio 2012, IIS Express is the default server for web development.

Whether that is version 7.5 or 8.0 I don't know.

I moved it to the local IIS on my Windows 7 machine, so under debug menu and [project] properties, start options, set the server to use custom server and pointed it to localhost
I do have a development server too running Windows 2008 server with IIS but, having just as much bother playing with remote debugging. I think it will be simpler to try and get it working on local.

The version of IIS that comes with windows 7 should be 7.5 I think.

Whether that is version 7.5 or 8.0 I don't know.

It is true that IIS Express is the default but the alternative is Visual Studio Development Server and the OP specifically said:

I have a couple of issues with the VS2012 development server.

so it's not clear exactly what the web server that was causing issues was.

 

[Lotok]

Just to clarify. My understanding was < VS2010 was cassini and VS2012 is IIS Express
I hadnt changed the development server away from IIS.

I have now changed it to local but it doesn't work. is there anything specific you know of to set up on the local IIS to allow debugging other than ofcourse setting it under custom server in VS?

Cheers

[edit]
There is a checkbox in settings allowing you to disable the use of IIS. I hadnt used that, so IIS was/is still active.
