Json Web Token JWT have performance overhead? I wanted to find out if using jwt token during authentication of a web application creates any performance issue. But what are Jwt Tokens you may ask? JSON Web Token (JWT) is an open standard (RFC 7519) that defines a compact and self-contained way for securely transmitting information […]

Redis List Datatype are similar in C# world as LinkeList e.g LinkedList. Just like in LinkedList in C#, Redis can store items at Head or Tail of a List. The nice thing about them is that the insertion speed is just O(1), but do note that if you have a large list, the reading speed […]
I wanted to cover some security aspect of Redis, using Redis Password feature. Redis uses config file to provide a password for it. The config file is usually located at /etc/redis/redis.conf if you are using linux. Look for the SECURITY section.

Continuing on with our Redis for .NET Developer, the Redis String Datatype is also used to store integers, float and other utility commands to manipulate strings. Redis String Datatype using Integers In Redis float and integers are represented by string. Redis parses the string value as an integer and the neat thing about them is […]
In the second blog post series “Redis for .NET Developer” I will show how we will use C# to connect to Redis. If you want to learn how to install Redis, visit my previous post on Intro to Redis for .NET Developers – Installing Redis on Windows. We will be using StackExchange.Redis library to connect […]
I just got back from MVP summit from Seattle, and there were lots of new and cool stuff about the future of .NET and web development with vNext. I would strongly to suggest that you join the virtual developer Microsoft conference Connect(); http://www.visualstudio.com/en-ca/connect-event-vs On the 12th you will have keynotes from Scott Gu, Scott Hanselman […]
Here is a quick C# tip of counting up values of a Dictionary<TKey, TValue> where the values contains a List<T> using Linq. Lets say you have a Dictionary that contains Dictionary<string, List<Guid>> and you wish to find out how many items of Guid you have. You can easily do it by the Sum Linq aggregate […]
Here is a quick C# tip, when using string compare don’t use
|
1 2 3 |
var str = "Hello"; if(str.ToLower() === "hello") |
use the Equals and StringComparison.InvariantCultureIgnoreCase enum.
|
1 2 3 |
var str = "Hello"; if(str.Equals("hello", StringComparison.InvariantCultureIgnoreCase)) |
The thing you need to note is which rules are appropriate current culture, the invariant culture, ordinal or another culture entirely. One can create the compare from StringComparer.Create(culture, true)
Here is another C# tip. Most of the time when you are trying to get a value from dictionary you would try to check if the key exist or not something like.
|
1 2 3 4 5 6 |
if(dictionary.ContainsKey(key)) { var value - dictionary[key]; //do some stuff } |
But one can use TryGetValue
|
1 2 3 4 |
if(dictionary.TryGetValue(key, out value)) { //do stuff with value } |
The benefit of using TryGetValue is that the dictionary is synchronized, there is no race condition.
Here is a hint when using WPF and you may come into a situation where you want to databind an element to its Parent ViewModel. As an example lets say you have a view that is binding to ViewModel and inside your xaml you have a control that has DataTemplate The code Below we are […]
