An assembly in .NET is a collection of types and resources that form a logical unit. Assemblies can contain metadata about types using attributes. Attributes provide additional information that can be attached to classes, methods, and other members. There are built-in attributes in .NET and custom attributes can be created by deriving from the Attribute base class. Built-in attributes like Required and StringLength are used to validate model data in ASP.NET MVC. A custom MyLicenseAttribute was created to require a license key by applying the attribute to assemblies. Attributes help add metadata and customize behavior.

Assemblies are the building blocks of .NET Framework ; they form the basic unit of deployment, reuse, version control, reuse, activation scoping and security permissions. An assembly is a collection of types and resources that are created to work together and form a functional and logical unit.
.NET assemblies are self-describing, i.e. information about an assembly is stored in the assembly itself. This information is called Metadata. .NET also allows you to put additional information in the metadata via Attributes. Attributes are used in many places within the .NET framework.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

Assemblies are the building blocks of .NET Framework ; they form the basic unit of deployment, reuse, version control,
reuse, activation scoping and security permissions. An assembly is a collection of types and resources that are created to
work together and form a functional and logical unit.
.NET assemblies are self-describing, i.e. information about an assembly is stored in the assembly itself. This
information is called Meta data. .NET also allows you to put additional information in the meta data via Attributes.
Attributes are used in many places within the .NET framework.
This page discusses what attributes are, how to use inbuilt attributes and how to customize attributes.
Define .NET Attributes
A .NET attribute is information that can be attached with a class, an assembly, property, method and other members. An
attribute bestows to the metadata about an entity that is under consideration. An attribute is actually a class that is either
inbuilt or can be customized. Once created, an attribute can be applied to various targets including the ones mentioned
above.
For better understanding, let’s take this example:
[WebService]public class WebService1 : System.Web.Services.WebService
{
[WebMethod]
3. // Revision
//
// You can specify all the values or you can default the Revision and Build Numbers
// by using the ‘*’ as shown below:
[assembly: AssemblyVersion("1.0.0.0")]
[assembly: AssemblyFileVersion("1.0.0.0")]
As you can see there are many attributes such as AssemblyTitle, AssemblyDescription and AssemblyVersion. Since
their target is the hidden assembly, they use [assembly: <attribute_name>] syntax.
Information about the features can be obtained through reflection. Most of the inbuilt attributes are handled by .NET
framework internally but for custom features you may need to create a mechanism to observe the metadata emitted by
them.
Inbuilt Attributes
In this section you will use Data Annotation Attributes to prove model data. Nees to start by creating a new ASP.NET
MVC Web Application. Then add a class to the Models folder and name it as Customer. The Customer class contains
two public properties and is shown below:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
5. using System.ComponentModel.DataAnnotations;
namespace CustomAttributesMVCDemo.Models
{
public class Customer
10. {
[Required]
public string CustomerID { get; set; }
[Required]
15. [StringLength(20,MinimumLength=5,ErrorMessage="Invalid company name!")]
public string CompanyName { get; set; }
}
}
4. Take note of the above code. The Customer class comprise of two string properties – CustomerID and CompanyName.
Its important to note that these properties are decorated with data annotation features residing in the
System.ComponentModel.DataAnnotations namespace.
The [Required] features points that the CustomerID property must be given some value in order to consider it to be a
valid model. Similarly, the CompanyName property is designed with [Required] and [StringLength] attributes. The
[StringLength] feature is used to specify that the CompanyName should be a at least five characters long and at max
twenty characters long. An error message is also specified in case the value given to the CompanyName property
doesn’t meet the criteria. To note that [Required] and [StringLength] attributes are actually classes – RequiredAttribute
and StringLengthAttribute – defined in the System.ComponentModel.DataAnnotations namespace.
Now, add the HomeController class to the Controllers folder and write the following action methods:
public ActionResult Index()
{
return View();
}
5.
public ActionResult ProcessForm()
{
Customer obj = new Customer();
bool flag = TryUpdateModel(obj);
10. if(flag)
{
ViewBag.Message = “Customer data received successfully!”;
}
else
15. {
ViewBag.Message = “Customer data validation failed!”;
}
return View(“Index”);
}
The Index() action method simply returns the Index view. The Index.cshtml consists of a simple <form> as given
below:
<form action=”/home/processform” method=”post”>
<span>Customer ID : </span>
5. <input type=”text” name=”customerid” />
<span>Company Name : </span>
5. <input type=”text” name=”companyname” />
<input type=”submit” value=”Submit”/>
</form>
<strong>@ViewBag.Message</strong>
<strong>@Html.ValidationSummary()</strong>
The values entered in the customer ID text box and company name text box are submitted to the ProcessForm() action
method.
The ProcesssForm() action method uses TryUpdateModel() method to allot the characteristics of the Customer model
with the form field values. The TryUpdateModel() method returns true if the model properties contain proven data as
per the condition given by the data annotation features, otherwise it returns false. The model errors are displayed on the
page using ValidationSummary() Html helper.
Then run the application and try submitting the form without entering Company Name value. The following figure
shows how the error message is shown:
Thus data notation attributes are used by ASP.NET MVC to do model validations.
Creating Custom Attributes
In the above example, some inbuilt attributes were used. This section will teach you to create a custom attribute and
then apply it. For the sake of this example let’s assume that you have developed a class library that has some complex
business processing. You want that this class library should be consumed by only those applications that got a valid
license key given by you. You can devise a simple technique to accomplish this task.
Let’s begin by creating a new class library project. Name the project LicenseKeyAttributeLib. Modify the default class
from the class library to resemble the following code:
namespace LicenseKeyAttributeLib
{
[AttributeUsage(AttributeTargets.All)]
public class MyLicenseAttribute:Attribute
5. { public string Key { get; set; }
}
}
6. As you can see the MyLicenseAttribute class is created by taking it from the Attribute base class is provided by the
.NET framework. By convention all the attribute classes end with “Attribute”. But while using these attributes you don’t
need to write “Attribute”.
Thus MyLicenseAttribute class will be used as [MyLicense] on the target.
The MyLicenseAttribute class contains just one property – Key – that represents a license key.
The MyLicenseAttribute itself is decorated with an inbuilt attribute – [AttributeUsage]. The [AttributeUsage] feature is
used to set the target for the custom attribute being created.
Now, add another class library to the same solution and name it ComplexClassLib. The ComplexClassLib represents the
class library doing some complex task and consists of a class as shown below:
public class ComplexClass1
{
public string ComplexMethodRequiringKey()
{
5. //some code goes here
return “Hello World!”;
}
}
The ComplexMethodRequiringKey() method of the ComplexClass1 is supposed to be doing some complex operation.
Applying Custom Attributes
Next need to add an ASP.NET Web Forms Application to the same solution.
Then use the ComplexMethodRequiringKey() inside the Page_Load event handler:
protected void Page_Load(object sender, EventArgs e)
{
ComplexClassLib.ComplexClass1 obj = new ComplexClassLib.ComplexClass1();
Label1.Text = obj.ComplexMethodRequiringKey();
}
7. The return value from ComplexMethodRequiringKey() is assigned to a Label control.
Now it’s time to use the MyLicenseAttribute class that was created earlier. Open the AssemblyInfo.cs file from the web
application and add the following code to it:
using System.Reflection;
…
using LicenseKeyAttributeLib;
5. …
[assembly: MyLicense(Key = "4fe29aba")]
The AssemblyInfo.cs file now uses MyLicense custom attribute to specify a license key. Notice that although the
attribute class name is MyLicenseAttribute, while using the attribute you just mention it as MyLicense.
Summary
Attributes help you to add metadata to their target. The .NET framework though provides several inbuilt attributes ,
there are chances to customize a few more. You knew to use inbuilt data notation features to validate model data; create
a custom attribute and used it to design an assembly. A custom feature is a class usually derived from the Attribute base
class and members can be added to the custom attribute class just like you can do for any other class.
