AppData location when running under System user account

As it took far too much Googling to find this, if you need to access the AppData folder for the System account, go here:

C:\Windows\System32\config\systemprofile\AppData\Local C:\Windows\SysWOW64\config\systemprofile\AppData\Local I hit this because we needed to clear the NuGet package cache for a TeamCity build agent which was running as a service under the System account.

Get ASP.NET auth cookie using PowerShell (when using AntiForgeryToken)

At FundApps we run a regular SkipFish scan against our application as one of our tools for monitoring for security vulnerabilities. In order for it to test beyond our login page, we need to provide a valid .ASPXAUTH cookie (you’ve renamed it, right?) to the tool.

Because we want to prevent Cross-site request forgeries to our login pages, we’re using … Read more “Get ASP.NET auth cookie using PowerShell (when using AntiForgeryToken)”

Using Gulp – packaging files by folder

GulpJS is a great Node-based build system following in the footsteps of Grunt but with (in my opinion) a much simpler and more intuitive syntax. Gulp takes advantage of the streaming feature of NodeJs which is incredibly powerful, but means in order for you to get the most out of Gulp, you certainly need some understanding of what is going … Read more “Using Gulp – packaging files by folder”

Forms Authentication loginUrl ignored

I hit this issue a while back, and someone else just tripped up on it so thought it was worth posting here. If you’ve got loginUrl in your Forms Authentication configuration in web.config set, but your ASP.NET Forms or MVC app has suddenly started redirecting to ~/Account/Login for no apparent reason, then the new simpleMembership(ish) provider is getting in the … Read more “Forms Authentication loginUrl ignored”

Updating Azure Virtual Network to use point-to-site feature

Scott recently announced support for point-to-site VPN connections into Azure – awesome! But what might not be so clear is how to enable it on your existing Virtual Network configuration – because you can’t make changes (at least through the UI) to your virtual network after it has been deployed and is in use.

Fortunately, there appears to be a … Read more “Updating Azure Virtual Network to use point-to-site feature”

Disabling Chrome’s Metro app in Windows 8

At time of writing, if you replace IE with Chrome on Windows 8 then Chrome installs both a desktop and a Metro version of itself. Personally, as most of my time is spent in the desktop, I’d rather Chrome just always opened there.

There’s currently an open issue on the chromium website, but in the meantime there’s a relatively simple … Read more “Disabling Chrome’s Metro app in Windows 8”

Migrating old websites & Rewrite maps in IIS 7

If you’re migrating to a new website and need to map old IDs to new IDs, I’ve just discovered that the UrlRewrite plugin in IIS has a great feature I hadn’t come across before called rewriteMaps. This means instead of writing a whole bunch of indentical looking rewrite rules, you can write one – and then simply list the ID … Read more “Migrating old websites & Rewrite maps in IIS 7”

Debugging InstallUtil service installation

If you’re using the Installer class and either InstallUtil or calling the helper methods directly, you might want to attach the debugger to actually track down problems with the code. One simple line:

System.Diagnostics.Debugger.Launch();

will then launch a prompt to pick a debugger to step into the problem code.
