0
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.

SqlBulkCopy with model classes in C#

Use SqlBulkCopy with model (POCO) classes in C#
 
0
So far (based on my experience) the fastest way to insert big number of records from application to database is to use SqlBulkCopy. The downsize of this is that SqlBulkCopy uses DataTable instace as an input parameter which is not so convenient when dealing with models which are strongly typed and a lot more easy to use than iterating through the DataTable. Since SqlBulkCopy accepts DataTable for insert you can not use models directly to insert your data...read more

An easier way to debug and develop Windows Services

Developing Windows Service might a a real headache since you do not have any visual part to see the output. Even if you want to rely on Visual Studio debugger you need to install the service, stop it (if already running), deploy, start the service from Windows MMC and finally hook up Visual Studio to the running service process.

However idea of executing tasks in a single Windows Service is very useful if you need to execute task in a short time span plus you have a full control including logging and other fine grained customization in case you write the task in your code. ...read more

MSMQ JSON message formatter

Use JSON to serialize and deserialize message queue messages
0
Storing objects in the message queue (MSMQ) is based on the serialization of the object instance using some of the serializes, basically any class the implements IMessageFormatter. Most commonly used ones are BinaryMessageFormatter and XmlMessageFormatter. I prefer XmlMessageFormatter over BinaryMessageFormatter, mostly because messages are stored in a readable format inside the queue, so in case something goes wrong you can direly check the content of the message using built Computer Management MMC (Microsoft management console) in the. ...read more
