One of the requirements beside referencing Microsoft.Web.Administration library is setting your Application Pool to run under LocalSystem account. ...read more

Using REDIS for caching values for increasing application performance can be quite beneficial and can increase performance and scalability of your application. Although REDIS allows quite large text files, up to 512MB which is something you most likely will not reach if you are storing for example JOSN data, there will be a significant network transfer over the wire for putting and pulling this value in and out...read more

This article is based on one of my previous topic Advanced Base64 image extension in ASP.NET MVC. It uses the same concept to display image on the page and to cache it, but it involves QR code bitmap generation which is basically a NuGet package use. Basically, QR code is generated using NuGet package QRCoder https://www.nuget.org/packages/QRCoder/ and result Bitmap is serialized to base64 string and cached so we do not regenerate same QR bitmap over and over on every request which may lead to server overload. ...read more

MSMQ is a bit old stuff and there are bunch of other products out here which perform better in most of the scenarios, but MSMQ is still used in a lot of solutions and Microsoft still did not announce support ending for MSMQ so it will be for sure some more time around.One of the stuff that is missing as out of the box feature in MSMQ is recovery.

Although JSON is widely used as a format for sharing the data, there are still existing solutions or modules that still rely on ADO and DataTables. Even today it very common to see some piece of code which deals with DataTable or DataReader for the performance reasons.

So far (based on my experience) the fastest way to insert big number of records from application to database is to use SqlBulkCopy.
