Old Zhao's. NET program performance of the basic EssentialsSpeaking of Roslyn everyone must have heard, this is the next generation of C # and vb.net compiler implementation. Roslyn is developed using pure managed code, but performance is more than a native implementation written in C + + before. Bill Chiles is Roslyn's PM (Program Manager), who recently wrote an article called The Essential Performance Fac
The thread pool is the process of fetching/returning threads from a number of predesigned threads and reusing threads to save the overhead of frequently creating new destruction threads.
In the same vein, object pooling is used to reclaim/return objects from many of the same objects that have been created in advance, and to save the overhead of creating destruction objects frequently by reusing objects.
Object pooling is used for concurrent multithreaded operations, so object pooling is generall
. Unfortunately, I didn't find any ORM doing this, The DC mechanism in XAF implements similar function, using interface to do ORM model, the effect is very good, but, the performance has dropped some, some behavior realizes is not very good. form Features
Let's take a look at the creation of the form:
The essence of a form is the addition of two ordinary business objects, that is, the master table structure, and this form is very common, such as a set of ERP will have n hundreds of forms, so ci

In the company forum, I saw a post called "high quality coding is required", which was developed by the Technical Research Department. There is a PDF in the attachment, curious. I downloaded it and read it, I think it is not bad, so I would like to share with you some of the key points that I think are more useful. If you are interested, you can download the file and read it. The content is easy to understand and is very suitable.

First, Introduction In scenarios other than MVC , we often need to complete some template engine generated code or page work, in the past we generally used to have Razor,nveocity,vtemplate. While all templating systems have some common features, Razor is quite different from the two view engines we discussed earlier. Unlike other view engines, Razor does not go so far in using XML code. It is also not exactly like ASPX, because it replaces the more cumbersome placeholders with the @ sign-on expr
This two-day attempt to compile a. NET cross-platform (CORECLR/COREFX/DNX) Corefx (.

Although ASP. NET Web Forms is not part of the vNext plan, it is not ignored. As part of Visual Studio 2013 Update 2, it restarts to support new tools, EF integration, and Roslyn.
Why Web Forms is not part of ASP. NET vNext
In the beginning, Let's explain the bad news first. To improve performance and cross-platform portability, ASP. NET vNext is eliminating dependency on System. Web. Compared with OWIN, it is slow and huge, making the test work much

Next let's take a look at form creation:
The essence of a form is the addition of two common business objects, that is, the structure of the primary table and child table. This form is very common. For example, a set of ERP contains N hundred forms, therefore, CIIP specizes this form and puts the content of the master table and sub-table

1. allow "embedded" combinations of objects: To put it bluntly, an object can contain other objects (including the object itself, rather than its reference ), in this way, multiple objects are merged into one object, which reduces the number of objects and reduces the natural GC pressure. The contained object is actually equivalent to a struct and cannot be referenced by it. If the object to be included is an array, at least
