You need to call sc again to set the description. For example:

    sc description TestService1 &quot;This is the description of the service..&quot;

For more information, see [here][1].


  [1]: https://technet.microsoft.com/en-us/library/cc742069.aspx

Is not 

    sc description TestService1 &quot;TestService1&quot;

as per documentation: https://technet.microsoft.com/en-us/library/cc742069.aspx  ?

For those experiencing &quot;A positional parameter cannot be found that accepts argument&quot; (PositionalParameterNotFound) error while trying to use the &quot;sc description&quot; command, replace sc with sc.exe. Apparently it fixes the problem, although the &quot;sc create&quot; command works as expected, without .exe 

Now that API v2 is gone, what would be a way to get a simple RSS feed of a channel, without v3 API? I&#39;m open to Yahoo Pipes or any workaround that is simpler than creating an application for v3 API if the target is a feed reader. I only need an RSS feed. It was available publicly until now and it can cease any minute now (I think). So why not let access to it without an API key anymore.

I see the following in almost every future .NET framework discussion:

 - .NET Framework 4.6 (Full .Net framework)
 - .NET Native
 - .NET Core

What is the difference between all of these? 

How do I know when to use the appropriate one?

According to [this blog post](http://cpratt.co/migrating-production-database-with-entity-framework-code-first/) most companies using EF Migrations are supposedly not updating the database schema of production databases with EF migrations. Instead the blog post&#39;s author recommends to use Schema update scripts as part of the deployment process. 

I&#39;ve used Schema update scripts for a few years now and while they work, I was planning to use EF migrations instead in the future for the following reasons: 

- Faster deployment, less downtime
- A simpler deployment procedure
- Much easier migration of existing data than it would be possible with T-SQL
- A more comprehensible syntax of the changes waiting to be applied (DbMigration class with clean C# syntax vs. clunky T-SQL Migration script in a traditional environment).
- There is an easy and fast downgrade path to the old db schema if the deployment of the new software version should fail

One reason I can think of that would prohibit the use of EF to migrate a production DB would be if the DB schema was only altered by the DBAs as opposed to the Developers. However, I am both DBA and Developer, so this does not matter in my case.

So, what are the risks of updating a production database using EF?

Edit: I would like to add that, as solomon8718 already suggested, I am always pulling a fresh copy of the production database to my staging server and test the EF Migrations to be applied on the staging server before applying them to a production server. IMO this is essential for any schema update to a production system, whether I&#39;m using EF migrations or not. 




Is it OK to update a production database with EF migrations?

I have a need to create a list of combinations of numbers. The numbers are quite small so I can use `byte` rather than `int`. However it requires many nested loops in order to get every possible combination. I&#39;m wondering if there&#39;s a more efficient manner to do what I&#39;m after. Code so far is:

    var data = new List&lt;byte[]&gt;();
    for (byte a = 0; a &lt; 2; a++)
	for (byte b = 0; b &lt; 3; b++)
	for (byte c = 0; c &lt; 4; c++)
	for (byte d = 0; d &lt; 3; d++)
	for (byte e = 0; e &lt; 4; e++)
	for (byte f = 0; f &lt; 3; f++)
	for (byte g = 0; g &lt; 3; g++)
	for (byte h = 0; h &lt; 4; h++)
	for (byte i = 0; i &lt; 2; i++)
	for (byte j = 0; j &lt; 4; j++)
	for (byte k = 0; k &lt; 4; k++)
	for (byte l = 0; l &lt; 3; l++)
	for (byte m = 0; m &lt; 4; m++)
	{
		data.Add(new [] {a, b, c, d, e, f, g, h, i, j, k, l, m});
	}

I was considering using something like a `BitArray` but I&#39;m not sure how I could incorporate it.

Any recommendations would be greatly appreciated. Alternatively, perhaps this is the fastest way of doing what I want?

**EDIT**
Couple of quick points (and apologies I didn&#39;t put these in the original post):

 - The numbers and the order of them (2, 3, 4, 3, 4, 3, 3 etc) are very important, so using a solution such as [https://stackoverflow.com/questions/4319049/generating-permutations-using-linq] [1] won&#39;t help because the maximums in each &#39;column&#39; are different
 - I&#39;m not a mathematician, so I apologise if I&#39;m not using the technical terms like &#39;permutations&#39; and &#39;combinations&#39; correctly :)
 - I **do** need to populate all of these combinations at once - I can&#39;t just grab one or another based on an index
 - Using `byte` is faster than using `int`, I **guarantee** it. It&#39;s also a lot better on memory usage to have 67m+ arrays of bytes rather than ints
 - My ultimate goal here is to look for a faster alternative to nested loops.
 - I considered using parallel programming, but due to the iterative nature of what I&#39;m trying to achieve, I couldn&#39;t find a way to do it successfully (even with `ConcurrentBag`) - however I&#39;m happy to be proved wrong :)

**CONCLUSION**

Caramiriel has provided a good micro-optimisation which shaves some time off the loops, so I&#39;ve marked that answer as correct. Eric also mentioned that it is faster to pre-allocate the List&lt;byte[]&gt;. But, at this stage it seems that the nested loops are in fact the fastest possible way of doing this (depressing, I know!).

If you want to try exactly what I was trying to benchmark with `StopWatch`, go with 13 loops counting up to 4 in each loop - that makes about 67m+ lines in the list. On my machine (i5-3320M 2.6GHz) it takes about 2.2s to do the optimised version.

Faster alternative to nested loops?

I planned to use ASP.NET Identity 2.0 in an ASP.NET MVC application for authentication and authorization.

Referring the below link

[JSON Web Token in ASP.NET Web API 2 using Owin][1]


  [1]: http://bitoftech.net/2014/10/27/json-web-token-asp-net-web-api-2-jwt-owin-authorization-server/

I was able to create a access token(JWT) for the valid user i.e., When user Logs in to the application I will validate the user with name and password then I will issue a JSON web token for that valid user.

Now, I read in some articles that we need to pass the bearer token in headers for every request to validate the user for authentication. In MVC we will provide Authorize attribute for the methods that needs to be protected as shown below…

          public class UserController : BaseHRAppController
          {
                [Authorize]
                public ActionResult Index()
                {          
                   return View();
                }
           }

How to tell my MVC application to use JWT for validating the user?

I want to make my MVC application validate the user using JWT whenever the user tries to access the method with authorize attribute. Since I will use AJAX calls in many pages to access method present in MVC controller, I don&#39;t think it&#39;s good to pass a token on every AJAX request. I need help to accomplish authentication and authorization in an efficient way using ASP.NET Identity in an MVC applicaton. 

Currently, I don&#39;t know how to use this JWT token for authentication and authorization in an MVC application.

I&#39;m implementing an API made by other colleagues with Apiary.io, in a Windows Store app project.

They show this example of a method I have to implement:

    var baseAddress = new Uri(&quot;https://private-a8014-xxxxxx.apiary-mock.com/&quot;);

    using (var httpClient = new HttpClient{ BaseAddress = baseAddress })
    {
        using (var response = await httpClient.GetAsync(&quot;user/list{?organizationId}&quot;))
        {
            string responseData = await response.Content.ReadAsStringAsync();
        }
    }

In this and some other methods, I need to have a header with a token that I get before.

Here&#39;s an image of Postman (chrome extension) with the header I&#39;m talking about:
![enter image description here][1]

How do I add that Authorization header to the request?

When I am querying from database in continuous looping, after some time 
I get an error :

&gt; An exception has been raised that is likely due to a transient
&gt; failure. If you are connecting to a SQL Azure database consider using SqlAzureExecutionStrategy.

Normally it is working fine.
