I think what you found seems correct. I had the same question then I had a look under my installed packages when you go &quot;Manage Nuget packages&quot;. There was an item installed with the name &quot;Microsoft ASP.NET WEB API 2.2&quot;. So I was able to determine my own version from there.

I&#39;m not sure what @John meant with the package name above. I&#39;m having the following package right now:

    Microsoft.AspNet.WebApi.5.2.3

Based on this article http://www.asp.net/web-api/overview/releases/whats-new-in-aspnet-web-api-22 I assume that starting from the package version 5.2.2 it&#39;s Web API 2.2 version. 

I always try this instead -

In the controller make a method

    public IHttpActionResult MyResult(){
        return Ok();
    }
If you get compilation error then it is API 1.0.

If no compilation error then you are referencing API 2.0.

I was reading the documentation for https://github.com/rvagg/bl and I noticed that, in the examples, they use **const** to require a module and this made me wonder: is this a good practice? I mean, to me, this looked as a good idea.

A direct example from the link above is:

    const BufferList = require(&#39;bl&#39;)

    var bl = new BufferList()
    bl.append(new Buffer(&#39;abcd&#39;))
    bl.append(new Buffer(&#39;efg&#39;))
    /*...*/

I also noticed the lack the semicolons in the example but well, that has been discussed elsewhere thoroughly.



Is there an efficiency difference between const vs var while &#39;requiring&#39; a module in NodeJS

**Introduce the problem**

I would like to know whether we are using Web API 1 or 2. My own packages.config indicates version 5.0.0. Is that Web API 1 or 2?

**Search, and research**

I have tried Googling the following: 

&gt;&quot;web api 1&quot; &quot;web api 2&quot;

and

&gt;ASP.NET Web API release history

and 

&gt;ASP.NET Web API nuget

The best references seem to be these two nuget pages:

- [ASP.NET Web API Nuget] seems to indicate that anything 4.* is Web API 1, 
- [Microsoft ASP.NET Web API 2.1 Nuget] that anything 5.* is Web API 2. 

Is that right? How would I know for sure?

I&#39;m migrating from Identity 1.0.0 to Identity 2.0.1 following this [article][1]

and the migrations code generated is nothing about the new IdentityUser. It doesn&#39;t add the new columns. 

So I made a new project and tried again but the migrations codes is empty. 

To fix that problem, I did the edits directly in SQL Server and imported my database again in my solution. 

Now my `AspNetUser` is exactly the same as my `IdentityUser` as you can see

**IdentityUser**

	public virtual int AccessFailedCount { get; set; }

	public virtual ICollection&lt;TClaim&gt; Claims { get; }

	public virtual string Email { get; set; }

	public virtual bool EmailConfirmed { get; set; }

	public virtual TKey Id { get; set; }

	public virtual bool LockoutEnabled { get; set; }

	public virtual DateTime? LockoutEndDateUtc { get; set; }

	public virtual ICollection&lt;TLogin&gt; Logins { get; }

	public virtual string PasswordHash { get; set; }

	public virtual string PhoneNumber { get; set; }

	public virtual bool PhoneNumberConfirmed { get; set; }

	public virtual ICollection&lt;TRole&gt; Roles { get; }

	public virtual string SecurityStamp { get; set; }

	public virtual bool TwoFactorEnabled { get; set; }

	public virtual string UserName { get; set; }

 
**IdentityUser.cs**

    public class ApplicationUser : IdentityUser
    {
        public bool Has_accepted_policy { get; set; }
        public int user_type_id { get; set; }
    }

    public class ApplicationDbContext : IdentityDbContext&lt;ApplicationUser&gt;
    {
        public ApplicationDbContext()
            : base(&quot;DefaultConnection&quot;)
        {
            
        }
    }

**AspNetUser**

    public string Id { get; set; }

	[Required]
	[StringLength(256)]
	public string UserName { get; set; }

	public string PasswordHash { get; set; }

	public string SecurityStamp { get; set; }

	[StringLength(256)]
	public string Email { get; set; }

	public bool EmailConfirmed { get; set; }

	public bool Is_Active { get; set; }

	[Required]
	[StringLength(128)]
	public string Discriminator { get; set; }

	public int? user_type_id { get; set; }

	public bool Has_accepted_policy { get; set; }

	public string PhoneNumber { get; set; }

	public bool PhoneNumberConfirmed { get; set; }

	public bool TwoFactorEnabled { get; set; }

	public DateTime? LockoutEndDateUtc { get; set; }

	public bool LockoutEnabled { get; set; }

	public int AccessFailedCount { get; set; }

	... other virtual properties 


and when I try to register a user I have the following exception

&gt;The entity type ApplicationUser is not part of the model for the current context

at this line

 

    IdentityResult result = await UserManager.CreateAsync(user, model.Password);


My **startup.Auth.cs** 

    UserManagerFactory = () =&gt; new UserManager&lt;ApplicationUser&gt;(new UserStore&lt;ApplicationUser&gt;());

And in my **AccountController** I declare my `UserManager` like this

	public AccountController()
		: this(Startup.UserManagerFactory(), Startup.OAuthOptions.AccessTokenFormat)
	{
	}

	public AccountController(UserManager&lt;ApplicationUser&gt; userManager,
		ISecureDataFormat&lt;AuthenticationTicket&gt; accessTokenFormat)
	{
		UserManager = userManager;
		AccessTokenFormat = accessTokenFormat;
	}

    public UserManager&lt;ApplicationUser&gt; UserManager { get; private set; }

I haven&#39;t changed anything except the new properties in the `AspNetUser` class and it used to work well before the migration. 

There&#39;s a similar issue on [CodePlex][2] marked as fixed but they don&#39;t give the solution

Does anyone know how to fix this?


**EDIT**

To be sure I didn&#39;t do any mistakes when I edited my SQL database. I created another project and generated an Identity database and I changed the connection string for that database and I still have the same error.


**SOLUTION**

When I have edited my database I haven&#39;t noticed that in Identity 2.0.0 they changed the `User_Id` for `UserId` in `AspUserClaims` table. After doing that I had the same error but then I did what tschmit007 said about adding the `ApplicationDbContext` to the `UserStore` constructor and now it works. 

    UserManagerFactory = () =&gt; new UserManager&lt;ApplicationUser&gt;(new UserStore&lt;ApplicationUser&gt;(new ApplicationDbContext()));

I&#39;m using Bootstrap 3 in my project, and I want to use Bootstrap Glyphicons in ASP.net buttons.

Here is the code I used, though it didn&#39;t work out (I got a sample which uses Twitter Bootstrap `&lt;span&gt;` tags instead of `&lt;i&gt;` tags):

    &lt;asp:Button ID=&quot;btnRandom&quot;
        runat=&quot;server&quot;
        Text=&quot;&lt;span aria-hidden=&#39;true&#39;
            class=&#39;glyphicon glyphicon-refresh&#39;&gt;
            &lt;/span&gt;&quot;
        onclick=&quot;btnRandom_Click&quot; /&gt;

Maybe something extra should be done.

How can I get it to work? Thanks in advance for the replies.

I got an error using ASP.NET Identity in my app. 

&gt; Multiple object sets per type are not supported. The object sets
&gt; &#39;Identity Users&#39; and &#39;Users&#39; can both contain instances of type
&gt; &#39;Recommendation Platform.Models.ApplicationUser&#39;.

I saw a few questions about this error in StackOverflow. All indicate on two `DbSet` objects of the same type. But in my `DbContext` there aren&#39;t the same types of `DbSets`. Exception is thrown on `FindAsync()` method during logging in. 

    if (ModelState.IsValid)
        var user = await UserManager.FindAsync(model.UserName, model.Password);
        if (user != null &amp;&amp; user.IsConfirmed)
        {

The problem is I don&#39;t have two `DbSets` of the same type. My Contexts look like this:

    public class ApplicationDbContext : IdentityDbContext&lt;ApplicationUser&gt;
    {
        public ApplicationDbContext()
            : base(&quot;DefaultConnection&quot;)

When compiling [this][1] official project with Android Studio 0.82, it shows error note:

    Error:The project is using an unsupported version of the Android Gradle plug-in (0.9.2)


After some searching, I decide to manually change content in the build.gradle file in line

    classpath &#39;com.android.tools.build:gradle:0.9.+&#39;

to the gradle version that is installed in Android Studio.

The question is, can how to check the gradle version in my Android Studio?

I have a repository with only one branch (`master`). I&#39;m the only contributor to my repo.

I&#39;ve recently added a `tag`, both locally and pushed to GitHub. After making what I though was the last necessary commit, but now I realize I should have made one more change/commit.

So what I have is:

    commit 124
    commit 125
    commit 126 &lt;-- tag v1.0
    commit 127

and I want to move the `v1.0` tag to the next commit, ie: `127`, both locally and in GitHub.

How can I do that?

I need to find the OS name and version on Unix/Linux platform. For this I tried following:

1. `lsb_release` utility

2. `/etc/redhat-release` or specific file

But it does not seem to be best solution as LSB_RELEASE support is no longer for RHEL 7.

Is there any way that will work on any Unix or Linux platform?

I don&#39;t want to check my Laravel version in the command prompt (`php artisan --version`), but in the view itself.

Like this:

    &lt;?php
      $laravel_version = /*laravel version check code*/;
    ?&gt;

In the view:

    {{ $laravel_version }}

Do anyone know how I can do that? Maybe it isn&#39;t possible..?

In Android Studio when I use a `+` in the version number like:    
`com.android.support:recyclerview-v7:21.+`  
I get a &quot;Avoid using + in version numbers&quot; warning.  

But when I use a specific version number I can&#39;t always use the latest version. I have a lot of dependencies in my project.  

How do I check if a dependency has a newer version?  

Is there an Android Studio plugin (or something like that) to notify me when there is a newer version of a dependency?

**Edit:**  
Android Studio highlights the outdated Android Support Libraries and Google play services. But this is not available for other custom libraries.

I am using Microsoft Asp.net WebApi2 hosted on IIS. I very simply would like to log the request body (XML or JSON) and the response body for each post.

There is nothing special about this project or the controller processing the post. I am not interested in using logging frameworks like nLog, elmah, log4net, or the built-in tracing features of web API unless it is necessary to do so.

I am simply wanting to know where to put my logging code and how to get the actual JSON or XML from the incoming and outgoing request and response.

My controller post method:

    public HttpResponseMessage Post([FromBody])Employee employee)
    {
       if (ModelState.IsValid)
       {
          // insert employee into to the database
       }
    
    }

I have been reading about JWT.

But from what I read it is not an authentication mechanism but more like a crucial component in a Authentication mechanism.

I have currently implemented a solution which works,  but it was just to try out JWT and see how it works. But what I am after now is how one should make use of it. From my experience of it its basically just an encryption mechanism that gives you a unique encrypted key. You are also able to put information inside of this token.

I am wanting to implement it in terms on a ASP.NET web api 2 to be consumed by a mobile application.

So step 1:

 1. app =&gt; Server : Login (user, pasword)
 2. Server =&gt; app : Login OK, heres your JWT
 3. app =&gt; server : Get my profile (sends JWT with request)
     Server then decrypts JWT and determines the requests Identity.

Now this is just my understanding of it, Look I could be on the totally wrong path.

Is the Ideal of JWT so that you dont have to authenticate on every request? I just authenticate the users credentials once (on the initial login) and there on after the server can simply use JWT and no have to lookup the users pw and user in the DB?

I just want to use the JWT to Identity who the user is. I will then authorize then after i have authenticated them. As I know there is a big confused with the new MVC and Authentication and Authorization.

So what my question comes down to.

How can I safely and effectively Implement a Authentication Mechanism Using JWT?
I don&#39;t want to just cough something up that seems to work and not have any Idea of the security implications. I am sure that there exists a source some where that has possibly designed a secure mechanism that would suit my requirements.

My requirements are:

 - Must only have to check db for users credentials once off per session? Due to the use of bcrypt using a lot of resources to compare passwords.
 - Must be able to identify the user from their request. (I.e who they are, userId will be sufficient) and preferably without accessing the DB as well
 - Should be as low overhead as possible, with regards to resources on the server side processing the request. 
 - If an intruder had to copy a devices previous request, then he should not be able to access the real users data. (obviously)


Thanks

I have MVC 4.0 WebApi project with auto generated help [based on this](http://www.asp.net/web-api/overview/creating-web-apis/creating-api-help-pages).

My model classes are stored it another projects in my solution. Generation of xml file is enabled for every project (Project Properties -&gt; Build -&gt; OutPut -&gt; XML Documentation file - Enabled).

In local debug all is ok - xml files are copied to project directory and i see comments for fields / classes from another projects.

But when i use publish profile (to Folder), xml files don&#39;t copy to output folder. Only one xml file from main WebApi project is copied. So i don&#39;t see comments to classes from other projects.

I&#39;m following a Microsoft sample to implement email validation with Identity 2.0.0

I&#39;m stuck at this part

    public ApplicationUserManager UserManager
    {
       get
       {
          return _userManager ?? HttpContext.GetOwinContext().GetUserManager&lt;ApplicationUserManager&gt;();
       }
       private set
       {
          _userManager = value;
       }
    }

This works in an `controller` but `HttpContext` doesn&#39;t contain any `GetOwinContext` method in an **ApiController**.

So I tried `HttpContext.Current.GetOwinContext()` but the method `GetUserManager` doesn&#39;t exist.


I can&#39;t figure out a way to get the `UserManager` I build in **Startup.Auth.cs**


 

    // For more information on configuring authentication, please visit http://go.microsoft.com/fwlink/?LinkId=301864
    public void ConfigureAuth(IAppBuilder app)
    {
        //Configure the db context, user manager and role manager to use a single instance per request
        app.CreatePerOwinContext(ApplicationDbContext.Create);
        app.CreatePerOwinContext&lt;ApplicationUserManager&gt;(ApplicationUserManager.Create); 
        ...
    }


this line 

    app.CreatePerOwinContext&lt;ApplicationUserManager&gt;(ApplicationUserManager.Create);

calls the following function to configure the `UserManager`

    public static ApplicationUserManager Create(IdentityFactoryOptions&lt;ApplicationUserManager&gt; options, IOwinContext context)
    {
         var manager = new ApplicationUserManager(new UserStore&lt;ApplicationUser&gt;(context.Get&lt;ApplicationDbContext&gt;()));
         //Configure validation logic for usernames
         manager.UserValidator = new UserValidator&lt;ApplicationUser&gt;(manager)
         {
             AllowOnlyAlphanumericUserNames = false,
             RequireUniqueEmail = true
         };
    
         // Configure user lockout defaults
         manager.UserLockoutEnabledByDefault = true;
         manager.DefaultAccountLockoutTimeSpan = TimeSpan.FromMinutes(5);
         manager.MaxFailedAccessAttemptsBeforeLockout = 5;
    
         manager.EmailService = new EmailService();
    
         var dataProtectionProvider = options.DataProtectionProvider;
         if (dataProtectionProvider != null)
         {
             manager.UserTokenProvider = new DataProtectorTokenProvider&lt;ApplicationUser&gt;(dataProtectionProvider.Create(&quot;ASP.NET Identity&quot;));
         }
         return manager;
    }

 How can I access this `UserManager` in an `ApiController`?

            // What should I write here to download the file I receive from the WebAPI method?
        }).error(function (data, status) {
            // ...
