Using strongly typed objects with IDistributedCache instead of byte arrays

An easy way to cache any object to distributed cache store using .NET Core
0
Saving an object to distributed cache store in .NET Core requires your object to be serialized to byte array in order for SetAsync method on Microsoft.Extensions.Caching.Distributed.IDistributedCache interface implemented instance to save your object to the injected cache store instance. This means that what ever instance you have, you need to serialize it first to byte array.

I am pretty sure any of us used Thread.Sleep method to pause the current thread execution. Mostly this is used to simulate long running process during the test or debug. While this is fine to use for testing, if your intention is to actually schedule thread execution this is probably wrong way of doing it, simply because Thread.Sleep does not actually take as many milliseconds as you pass to the method as a parameter...read more

Reduce traffic by serializing JSON with different alias with Json.NET and C#

Reducing speed and increasing performance by reducing traffic with JSON size
0
