Windows 2008 Hosting - ASPHostPortal :: How to Fix - Failed to generate a user instance of SQL Server due to failure in retrieving the user's local application data path

clock November 24, 2011 06:53 by author Jervis

When you are trying to connect to a "user instance" of SQL Server from your Web application running on Windows 7 or Windows 2008 R2 and you’re getting a message that looks like this:

I will try to help you here.

Note: this error only happens if you have User Instance=true in your connection string. The IIS team made a change to the default identity of the worker process.   Starting with IIS 7.5, Application Pools run with a unique identity based on the Application Pool name, rather than NetworkService – the default identity for IIS6 and IIS7.  The primary reason for this change is to increase the security of IIS and Application Pools by default, providing a much better sandbox between Applications and other Windows services by default. 

Unfortunately, the new identity does not have a user profile, and as you can see from the error, this causes the SqlClient data stack to fail.  There are a few things you can do to "fix" this error: 

1) switch back to NetworkService
2) switch to a user account that has a local profile (like a real user / domain user account).  To do that, fire open IIS Manager and browse to Application Pools node for your computer.  Click on the AppPool for the application you are trying to run and select the “Advanced Settings” task (in yellow on right).  Select identity and choose NetworkService as a built-in account, or select “Custom account” and type in the user/password. 

If you’re a command-line person, you can do it this way (all on one line):

%windir%\system32\inetsrv\appcmd.exe set config 
-section:system.applicationHost/applicationPools /[name='YOUR_APPPPOOL_NAME_HERE'].processModel.identityType:"NetworkService" 

WebMatrix Hosting - ASPHostPortal :: WebMatrix and jQuery Mobile

clock November 18, 2011 07:22 by author Jervis

Recently I have seen a number of examples using ASP.NET MVC with jQuery Mobile for displaying a list of blog posts to mobile devices. I thought I would show you similar code for doing this with the ASP.NET Web Pages Framework and Razor View Engine via WebMatrix. I want to warn you up front that the solution will seem too easy. One page, and only 1 page of code and markup is all that we will need to write to create the solution ( besides our sample database, of course ).

First things first, we need a database. Let's create a simple SQL Server CE 4 database right within WebMatrix itself. The database tooling feels a lot like SQL Server Management Studio, which is fantastic for new developers as they can take these skills with them for managing other versions of SQL Server. Here is a quick snapshot of the database definition:

Once we have the database defined and add a bit of data that I pulled from my blog, I can go ahead and create a blank Razor Page with all the necessary stylesheets, JavaScript files, HTML markup, and Razor code. You can click on the image to see a more viewable version of the page, but even now it looks way too easy.

 In the example, we connect to the database, define a query, and then execute the query and return the results. In this case the results are posts from the database. Further down the page we iterate through each post, displaying the date the post was published as well as a clickable title that takes you to the post.

The bonus here is that if the needs of your application grow, you can easily convert this to ASP.NET MVC 3. The top-most code gets swallowed up into a controller or service per your strategy for separating the concerns, leaving the HTML and Razor markup the same in the rest of the page.

Now here is the best part - click Run :)

You have a quick list of posts that give you a wonderful user experience on your mobile phone or tablet.
