kandi X-RAY | CommandQuery Summary

CommandQuery is a C# library. CommandQuery has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

Command Query Separation (CQS) for .NET Framework and .NET Core. Queries: Return a result and do not change the observable state of the system (are free of side effects). Commands: Change the state of a system but do not return a value. — Martin Fowler. The dogmatic approach to commands, that they do not return a value, can be inconvenient. CommandQuery has a more pragmatic take and supports commands with result.

QUESTION

Performance comparison of queries in SQL Server, ADO.NET and LINQ-to-SQL

Asked 2019-Oct-07 at 13:19

I'm wondering about the performance of the SQL queries executed in SQL Server and used in ADO.NET and LINQ-to-SQL.

I use the AdventureWorks database with extended Sales.SalesOrderDetailEnlarged table which has almost 5 million rows. Executing a query

Linq-to-SQL is actually a layer on top of ADO.NET, so why is it faster than ADO.NET

ADO.NET has two layers. The DataReader is the lower level, and is used by both your ADO.NET code and your L2S/EF code. The higher level in ADO.NET is the DataSet/DataTable/DataAdapter, which is a set of classes for loading query results into memory. That is not used by L2S/EF.

To measure just the query processing and tranmission of results to the client, .Read() through the rows in the DataReader, but don't do anything with the data.

QUESTION

ASP.NET Core and injecting IServiceProvider

Asked 2017-Feb-23 at 11:00

So, I've been reading about CQRS while deciding about architecture for my project and found this library. It's not very complex or anything like that but one thing caught my eye: here the ISeviceProvider is being injected and here it is being used. So, my question: is it a good practice to build objects with service provider directly, meaning without the injecting? If not which would be the correct way to build objects if the type of object will be known only in runtime?

Using IServiceProvider is basically the only option for DI (e.g. via RequestServices in MVC components) if you know the type at run-time.

Constructor injection is only viable if you know the type at compile-time, because you must specify the type of the object in the constructor.

Depending on the need, you can also register an implementation factory in ConfigureServices(), and give out different instances of some interface depending on runtime information.

EDIT: An example of an implementation factory in ASP.NET Core:
