Bibliotecas de clases de .NET | Microsoft Docs

Bibliotecas de clases .NET Standard. Las bibliotecas de .NET Standard son un reemplazo de los conceptos de bibliotecas específicas de la plataforma y portables. Son específicas de la plataforma ya que exponen toda la funcionalidad de la plataforma subyacente (sin plataformas sintéticas ni intersecciones de plataforma). Las bibliotecas de clases son el concepto de biblioteca compartida de .NET. Le permiten dividir funcionalidades útiles en módulos que pueden usar varias aplicaciones. También se pueden usar para cargar la funcionalidad no necesaria o no conocida al inicio de la aplicación. Las bibliotecas de clases se describen mediante el formato de archivo de Ensamblado de .NET.



Las bibliotecas específicas de la plataforma se enlazan a una única implementación de .NET (por ejemplo, .NET Framework en Windows) y, por tanto, pueden tomar dependencias significativas de un entorno de ejecución conocido. Este entorno expondrá un conjunto conocido de API (API de .NET y SO) y mantendrán y expondrán el estado esperado (por ejemplo, Registro de Windows).

Los desarrolladores que creen bibliotecas específicas de la plataforma pueden aprovechar al máximo la plataforma subyacente. Las bibliotecas solo se ejecutarán en esa plataforma determinada, por lo que las comprobaciones de plataforma u otras formas de código condicional son innecesarios (código de abastecimiento único de módulo para varias plataformas).

Las bibliotecas específicas de la plataforma han sido el tipo de biblioteca de clases principal de .NET Framework. Incluso con la aparición de otras implementaciones de .NET, las bibliotecas específicas de la plataforma continúan siendo el tipo de biblioteca dominante.

Las bibliotecas portables son compatibles con varias implementaciones de .NET. Pueden tomar dependencias en un entorno de ejecución conocido; en cambio, el entorno es sintético y está generado por la intersección de un conjunto de implementaciones concretas de .NET. Las hipótesis de plataforma y API expuestas son un subconjunto de lo que estaría disponible para una biblioteca específica de la plataforma.

Puede elegir una configuración de plataforma al crear una biblioteca portable. La configuración de plataforma es el conjunto de plataformas que tiene que admitir (por ejemplo, .NET Framework 4.5+, Windows Phone 8.0+). Cuantas más plataformas decida admitir, menos API y menos hipótesis de plataforma puede hacer, el mínimo común denominador. Esta característica puede ser confusa al principio, ya que la gente suele pensar que "más es mejor", pero más plataformas compatibles suponen menos API disponibles.

Muchos desarrolladores de bibliotecas han pasado de producir bibliotecas específicas de varias plataformas de un origen (con las directivas de compilación condicionales) a bibliotecas portables. Hay varios enfoques para acceder a la funcionalidad específica de la plataforma en las bibliotecas portables con bait-and-switch como la técnica más aceptada en este momento.

Las bibliotecas de .NET Standard son un reemplazo de los conceptos de bibliotecas específicas de la plataforma y portables. Son específicas de la plataforma ya que exponen toda la funcionalidad de la plataforma subyacente (sin plataformas sintéticas ni intersecciones de plataforma). Son portables ya que funcionan en todas las plataformas compatibles.

.NET Standard expone un conjunto de contratos de bibliotecas. Las implementaciones de .NET deben admitir cada contrato por completo o no admitirlo. Cada implementación, por tanto, admite un conjunto de contratos de .NET Standard. Como consecuencia, cada biblioteca de clases de .NET Standard es compatible con las plataformas que admiten sus dependencias del contrato.

.NET Standard no expone toda la funcionalidad de .NET Framework (ni es un objetivo); en cambio, expone muchas más API que las bibliotecas de clases portables. Se agregarán más API con el tiempo.

Las bibliotecas de clases se admiten en Mono, incluidos los tres tipos de bibliotecas que se han descrito anteriormente. A menudo, Mono se considera (correctamente) como una implementación multiplataforma de .NET Framework. En parte, se debía a que las bibliotecas de .NET Framework específicas de la plataforma podrían ejecutarse en el tiempo de ejecución Mono sin modificarse ni volver a compilarse. Esta característica ya existía antes de la creación de las bibliotecas de clases portables, por lo que era una elección obvia para habilitar la portabilidad binaria entre .NET Framework y Mono (aunque solo funcionaba en una dirección).

Bogus for .NET: C#, F#, and VB.NET - GitHub

Minimum Requirements: .NET Standard 1.3 or .NET Standard 2.0 or .NET Framework 4.0. Projects That Use Bogus. Elasticsearch .NET Client (NEST) FluentValidation; Microsoft Windows-XAML / Template10; Microsoft Learning / Developing Microsoft Azure Solutions; Microsoft Office Developer. Office 365 Development Training Content 📇 A simple and sane fake data generator for C#, F#, and VB.NET. Based on and ported from the famed faker.js.

Hello. I'm your host Brian Chavez (twitter). Bogus is a simple and sane fake data generator for .NET languages like C#, F# and VB.NET. Bogus is fundamentally a C# port of faker.jsand inspired by FluentValidation's syntax sugar.

Bogus will help you load databases, UI and apps with fake data for your testing needs. If you like Bogus star ⭐ the repository and show your friends! 😄 If you find Bogus useful consider supporting the project by purchasing a Bogus Premium license that gives you extra Bogus superpowers! 💫💪 You can also sponsor the project here! 💰💵

Note: Some locales may not have a complete data set. For example, zh_CN does not have a lorem data set, but ko has a lorem data set. Bogus will default to en if a locale-specific data set is not found. To further illustrate the previous example, the missing zh_CN:lorem data set will default to the en:lorem data set.

If you'd like to help contribute new locales or update existing ones please see ourCreating Locales wiki pagefor more info.

You can use Bogus without a fluent setup. The examples below highlight three alternative ways to use Bogus without a fluent syntax setup.

Bogus Premium [Purchase Now!] by @bchavezYou can help support the Bogus open source project by purchasing a Bogus Premium license! With an active premium license you'll be supporting this cool open-source project. You'll also gain new superpowers that extended Bogus with new features and exclusive data sets! Check 'em out below!

If you want to generate a Person with context relevant properties likean email that looks like it belongs to someone with the same first/last name,create a person!

The name of a dataset is determined using DataCategory attribute or class name otherwise. (i.e PhoneNumber dataset in handlebars expression should be named as phone_number)

Sometimes writing .RuleFor(x => x.Prop, ) can get repetitive, use the .Rules((f, t) => ) shortcut to specify rules in bulk as shown below:

Note: When using the bulk .Rules( ) action, StrictMode cannot be set to true since individual properties of type T cannot be independently checked to ensure each property has a rule.

The Enumerable.Range() and LINQ are a great supplement when creating data with Bogus. Here's how to generate a simple list of email addresses:

Determinism is a first class concept in Bogus. Bogus goes to great lengths so developers can generate the same sequence of data over multiple program executions. Bogus has two strategies of setting up deterministic behavior:

Global Seed determinism through the Randomizer.Seed global static property.Pros: Easy to get deterministic data setup quickly.Cons: Code changes can impact other data values. Not so good for unit tests.

Pros: Code changes can be isolated with minimal impact on determinism. Good for unit tests.Cons: Requires some forethought in design.

When Local Seed determinism is used to set a seed value, the global static source of randomness is ignored. This has some interesting implications as described below.

The easiest way to get deterministic data values over multiple executions of a program is to set the Randomizer.Seed property as demonstrated below:

Re-running the code above with 1338 as a global static seed value will produce the same table of data over and over again.

Next, add a new Description property to the Order class along with a new .RuleFor(o => o.Description, ..) rule and see the data changes:

In fact, every data value with a 🚩 icon has changed. This is due to the newly added property which has the effect of shifting the entire global static pseudo-random sequence off by +1. This rippling effect can be a problem if unit tests are expecting data values to remain the same. The following section below shows how we can improve the situation.

Making use of the Faker.UseSeed(int) method can help limit the impact of POCO schema changes on deterministic data values that span across an entire run. Consider the following code that uses a seed value for each instance of a POCO object:

Progress! This time only the Quantity data values with the 🚩 icon have changed. The Item column remained the same before and after the new addition of the Description property.

We can further prevent the Quantity data values from changing by moving the RuleFor(o => o.Description, ) rule line to the end of the Faker declaration as shown below:

Much success! 💯🎉 The Item and Quantity values remain unchanged! The new Description property is added to the POCO object without any impact to other deterministic data values.

The Faker facade and individual DataSets can also be prepared to use local seeds as well. The following shows how to set up the Faker facade and DataSets to use local seeds:

Updating to new versions of Bogus on NuGet can effect determinism too. For example, when Bogus updates locales from faker.js or issues bug fixes, sometimes deterministic sequences can change. Changes to deterministic outputs are usually highlighted in the release notes. Changes to deterministic outputs is also considered a breaking change. Bogus generally follows semantic versioning rules. For example:

With the Bogus.DataSets.Date.SystemClock set and a local or global seed, dates and times should be deterministic across multiple runs of a program.

The following section is only useful for people looking to contribute to Bogus or make custom modifications to Bogus. This section includes information about building Bogus from source code and is not required to operate or run Bogus in .NET applications.

asp.net - Unable to load shared library "libgdiplus" - Docker [ .NET

Here is how you can build a custom docker image to handle this problem in dotnetcore 2.2: I had to use this process to add all of the necessary libraries to my container so that it would work with system.drawing. The application is normally working with development environment when i create a docker file for deployment it getting failed with libgdiplus issue.

You're installing libgdiplus in your build container image, but not in your final container image. You need to make sure libgdiplus is installed in your final container image.

I had to use this process to add all of the necessary libraries to my container so that it would work with system.drawing. This may have to be updated for 3.1. I'm actually working on this today for 3.1 so i'll provide any updated instructions as I find them:

Multithreading in C - GeeksforGeeks

For example, in a browser, multiple tabs can be different threads. MS word uses multiple threads, one thread to format the text, other thread to process inputs, etc. Threads operate faster than processes due to following reasons: 1) Thread creation is much faster. 2) Context switching between threads is much faster.

Using an object of this class is straight forward. Simply open it, create a MIDI message, send the message, and close the device when you are done with it.

performance – Sitecore Architecture

It’s common for .Net libraries to copy their open source equivalents from the Java world (like Log4J has a .Net port for logging named Log4net, Lucene has a .Net port for search called Lucene.Net, etc). Solr.Net, however, is not a port of the Solr Java application to .Net. Instead, Solr.Net is a wrapper for the main Solr API elements that can be easily called by .Net applications.
