This file is managed by the NuGet infrastructure. It&#39;s used to track installed packages with their respective versions. If you installed the ASP.NET MVC 3 Tools Update it uses NuGet by default to track packages such as jQuery, EntityFramework, Modernizr. That&#39;s why you might be seeing this file when you create a new bare bone project.

To learn more about NuGet (and I highly recommend you do as it is one of the best things to be added to VS and C#/VB in years) look here:

I found that I am using a deprecated method for noficitations (notification.setLatestEventInfo())

It says to use Notification.Builder. 

- **How do I use it?**

When I try to create a new instance, it tells me:

    Notification.Builder cannot be resolved to a type



How exactly to use Notification.Builder

I&#39;m new to Regex and I&#39;m trying to work it into one of my new projects to see if I can learn it and add it to my repitoire of skills. However, I&#39;m hitting a roadblock here.

I&#39;m trying to see if the user&#39;s input has illegal characters in it by using the `.search` function as so:


    if (name.search(&quot;[\[\]\?\*\+\|\{\}\\\(\)\@\.\n\r]&quot;) != -1) {
        ...
    }

However, when I try to execute the function this line is contained it, it throws the following error for that specific line:

    Uncaught SyntaxError: Invalid regular expression: /[[]?*+|{}\()@.
    
    ]/: Nothing to repeat

I can&#39;t for the life of me see what&#39;s wrong with my code. Can anyone point me in the right direction?

Javascript + Regex = Nothing to repeat error?

The database is created successfully (as are the tables) but is not seeded. I have spent several hours and read tons of articles but have not been able to get it. Any suggestions?

On a side note, is it possible to call the initializer without having a reference to my DatabaseContext in the client?

I have included all the relevant code I could think of. If anything else would be helpful, please let me know.

Things I&#39;ve Tried:

1. I deleted my connection string (since it defaults to sqlexpress anyways, just the name changed)
2. I changed DropCreateDatabaseIfModelChanges to DropCreateDatabaseAlways, still the same.

Edit: The really weird thing is it worked once, but I have no idea how or why it broke again. I am assuming connection strings, but who knows.

DatabaseInitializer.cs

    public class DatabaseInitializer : DropCreateDatabaseIfModelChanges&lt;DatabaseContext&gt;
    {
      protected override void Seed(DatabaseContext context)
      {
        // Seeding data here
        context.SaveChanges();
      }
    }

DatabaseContext.cs

    public class DatabaseContext : DbContext
    {
      protected override void OnModelCreating(DbModelBuilder mb)
      {
        // Random mapping code
      }

      public DbSet&lt;Entity1&gt; Entities1 { get; set; }
      public DbSet&lt;Entity2&gt; Entities2 { get; set; }

    }
    
Global.asax.cs - Application_Start()

    protected void Application_Start()
    {
      Database.SetInitializer&lt;DatabaseContext&gt;(new DatabaseInitializer());
      AreaRegistration.RegisterAllAreas();
      RegisterGlobalFilters(GlobalFilters.Filters);
      RegisterRoutes(RouteTable.Routes);
    }

Client web.config

    &lt;connectionStrings&gt;
      &lt;add name=&quot;DatabaseContext&quot; connectionString=&quot;data source=.\SQLEXPRESS;Database=Database;Integrated Security=SSPI;&quot; providerName=&quot;System.Data.SqlClient&quot; /&gt;
    &lt;/connectionStrings&gt;

#SOLUTION#

For the sake of documentation, I am sharing my solution here. Navigating all the comments would be a pain anyways. In the end I had DatabaseInitializer and DatabaseContext in separate classes. I don&#39;t really understand while these tiny changes fixed it, but here it is.

DatabaseInitializer.cs

    public class DatabaseInitializer : CreateDatabaseIfNotExists&lt;DatabaseContext&gt;
    {
      protected override void Seed(DatabaseContext context)
      {
        // Seed code here
      }
    }

DatabaseContext.cs

    public class DatabaseContext : DbContext
    {
      public DatabaseContext() : base(&quot;MyDatabase&quot;) { }

      protected override void OnModelCreating(DbModelBuilder mb)
      {
        // Code here
      }
      
      public DbSet&lt;Entity&gt; Entities { get; set; }
      // Other DbSets
    }

Global.asax.cs - Application_Start()

    protected void Application_Start()
    {
      Database.SetInitializer(new DatabaseInitializer());
      AreaRegistration.RegisterAllAreas();
      RegisterGlobalFilters(GlobalFilters.Filters);
      RegisterRoutes(RouteTable.Routes);
    }

    

How can I get my database to seed using Entity Framework CodeFirst?

I am trying to make a very basic REST call to my MVC 3 API and the parameters I pass in are not binding to the action method.

**Client**
    
    var request = new RestRequest(Method.POST);

    request.Resource = &quot;Api/Score&quot;;
    request.RequestFormat = DataFormat.Json;
            
    request.AddBody(request.JsonSerializer.Serialize(new { A = &quot;foo&quot;, B = &quot;bar&quot; }));
            
    RestResponse response = client.Execute(request);
    Console.WriteLine(response.Content);

**Server**

    public class ScoreInputModel
    {
       public string A { get; set; }
       public string B { get; set; }
    }

    // Api/Score
    public JsonResult Score(ScoreInputModel input)
    {
       // input.A and input.B are empty when called with RestSharp
    }

Am I missing something here?

RestSharp JSON Parameter Posting

When I want a specific menu link to be active at a given page, I&#39;m using this approach in Razor:

On the master layout I have these checks:

    var active = ViewBag.Active;
    const string ACTIVE_CLASS = &quot;current&quot;;
    
    if (active == &quot;home&quot;)
    {
    	ViewBag.ActiveHome = ACTIVE_CLASS;
    }
    if (active == &quot;products&quot;)
    {
    	ViewBag.ActiveProducts = ACTIVE_CLASS;
    }

etc.

The html menu on the master layout:

    &lt;ul&gt;
    &lt;li class=&quot;@ViewBag.ActiveHome&quot;&gt;&lt;a href=&quot;/&quot;&gt;Home&lt;/a&gt;&lt;/li&gt;
    &lt;li class=&quot;@ViewBag.ActiveProducts&quot;&gt;&lt;a href=&quot;@Url.Action(&quot;index&quot;, &quot;products&quot;)&quot;&gt;Products&lt;/a&gt;&lt;/li&gt;
    &lt;/ul&gt;

When specifying which layout page to use on a different view:

    @{
    	ViewBag.Active = &quot;home&quot;;
    	Layout = &quot;~/Views/Shared/_Layout.cshtml&quot;;
    }

Is there a better approach to sepcify active links, than the one I&#39;m currently using?

Apologies if this has already been answered, but how do you guarantee one Entity Framework DbContext per request if you are not using an IOC container? (The answers I&#39;ve come across so far deal with IOC container solutions.)

It seems like most solutions hook into the `HttpContext.Current.Items` dictionary, but how do you guarantee disposal of the DbContext when the request is finished? (Or is disposal not absolutely necessary with an EF `DbContext`?)

**Edit**

I&#39;m currently instantiating and disposing my DbContext in my controllers, but I also have several separate instantiations of my DbContext in ActionFilters and my MembershipProvider (and I just noticed, also a couple validators). So, I thought it might be a good idea to centralize instantiation and storage of my DbContext to reduce overhead.

One DbContext per request in ASP.NET MVC (without IOC container)

I&#39;m using ASP.NET MVC 3 code-first and I have added validation data annotations to my models.  Here&#39;s an example model:

    public class Product
    {
        public int ProductId { get; set; }
        
        [Required(ErrorMessage = &quot;Please enter a name&quot;)]
        public string Name { get; set; }
        
        [Required(ErrorMessage = &quot;Please enter a description&quot;)]
        [DataType(DataType.MultilineText)]
        public string Description { get; set; }
        
        [Required(ErrorMessage = &quot;Please provide a logo&quot;)]
        public string Logo { get; set; }
    }

In my website I have a multi-step process to create a new product - step 1 you enter product details, step 2 other information etc. Between each step I&#39;m storing each object (i.e. a Product object) in the Session, so the user can go back to that stage of the process and amend the data they entered.

On each screen I have client-side validation working with the new jQuery validation fine.

The final stage is a confirm screen after which the product gets created in the database.  However because the user can jump between stages, I need to validate the objects (Product and some others) to check that they have completed the data correctly.

Is there any way to programatically call the ModelState validation on an object that has data annotations?  I don&#39;t want to have to go through each property on the object and do manual validation.

I&#39;m open to suggestions of how to improve this process if it makes it easier to use the model validation features of ASP.NET MVC 3.
