.NET 5 Preview 8 is now available and is ready for evaluation. Here’s what’s new in this release:
InputRadio
Blazor componentIAsyncDisposable
for Blazor componentsDynamicRouteValueTransformer
dotnet watch
See the .NET 5 release notes for additional details and known issues.
To get started with ASP.NET Core in .NET 5 Preview 8 install the .NET 5 SDK.
You need to use Visual Studio 2019 16.8 Preview 2 or newer to use .NET 5 Preview 8. .NET 5 is also supported with the latest preview of Visual Studio for Mac. To use .NET 5 with Visual Studio Code, install the latest version of the C## extension.
To upgrade an existing ASP.NET Core app from .NET 5 Preview 7 to .NET 5 Preview 8:
5.0.0-preview.8.*
.5.0.0-preview.8.*
.5.0.0-preview.8.*
.That’s it! You should be all ready to go.
See also the full list of breaking changes in ASP.NET Core for .NET 5.
The ASP.NET Core project templates now integrate with Microsoft.Identity.Web to handle authentication with Azure Activity Directory (Azure AD). The Microsoft.Identity.Web package provides a better experience for authentication through Azure AD as well as an easier way to access Azure resources on behalf of your users, including Microsoft Graph. Check out the Microsoft.Identity.Web sample that take you from a simple login through multi-tenancy, using Azure APIs, using Microsoft Graph, and protecting your own APIs. Microsoft.Identity.Web will be generally available alongside .NET 5.
Blazor now supports defining CSS styles that are scoped to a given component. Component specific CSS styles make it easier to reason about the styles in your app and to avoid unintentional side effects from global styles. You define component specific styles in a .razor.css file the matches the name of the .razor file for the component.
For example, let’s say you have a component MyComponent.razor file that looks like this:
MyComponent.razor
<h1>My Component</h1>
<ul class="cool-list">
<li>Item1</li>
<li>Item2</li>
</ul>
You can then define a MyComponent.razor.css with the styles for MyComponent:
MyComponent.razor.css
h1 {
font-family: 'Comic Sans MS'
}
.cool-list li {
color: red;
}
The styles in MyComponent.razor.css will only get applied to the rendered output of MyComponent; the h1
elements rendered by other components, for example, are not affected.
To write a selector in component specific styles that affects child components, use the ::deep
combinator.
.parent ::deep .child {
color: red;
}
By using the ::deep
combinator, only the .parent
class selector is scoped to the component; the .child
class selector is not scoped, and will match content from child components.
Blazor achieves CSS isolation by rewriting the CSS selectors as part of the build so that they only match markup rendered by the component. Blazor then bundles together the rewritten CSS files and makes the bundle available to the app as a static web asset at the path _framework/scoped.styles.css.
While Blazor doesn’t natively support CSS preprocessors like Sass or Less, you can still use CSS preprocessors to generate component specific styles before they are rewritten as part of the building the project.

We have created a theme editor
where you can define your own theme. We have also defined some themes ourselves, which can be installed and used directly. Below is a usage example:
import CodeMirror from '@uiw/react-codemirror';
import { javascript } from '@codemirror/lang-javascript';
import { okaidia } from '@uiw/codemirror-theme-okaidia';
const extensions = [javascript({ jsx: true })];
export default function App() {
return (
<CodeMirror
value="console.log('hello world!');"
height="200px"
theme={okaidia}
extensions={[javascript({ jsx: true })]}
/>
);
}
import CodeMirror from '@uiw/react-codemirror';
import { createTheme } from '@uiw/codemirror-themes';
import { javascript } from '@codemirror/lang-javascript';
import { tags as t } from '@lezer/highlight';
const myTheme = createTheme({
theme: 'light',
settings: {
background: '#ffffff',
foreground: '#75baff',
caret: '#5d00ff',
selection: '#036dd626',
selectionMatch: '#036dd626',
lineHighlight: '#8a91991a',
gutterBackground: '#fff',
gutterForeground: '#8a919966',
},
styles: [
{ tag: t.comment, color: '#787b8099' },
{ tag: t.variableName, color: '#0080ff' },
{ tag: [t.string, t.special(t.brace)], color: '#5c6166' },
{ tag: t.number, color: '#5c6166' },
{ tag: t.bool, color: '#5c6166' },
{ tag: t.null, color: '#5c6166' },
{ tag: t.keyword, color: '#5c6166' },
{ tag: t.operator, color: '#5c6166' },

{ tag: t.typeName, color: '#5c6166' },
{ tag: t.angleBracket, color: '#5c6166' },
{ tag: t.tagName, color: '#5c6166' },
{ tag: t.attributeName, color: '#5c6166' },
],
});
const extensions = [javascript({ jsx: true })];
export default function App() {
const onChange = React.useCallback((value, viewUpdate) => {
console.log('value:', value);
}, []);
return (
<CodeMirror

);
}
initialState
to restore state from JSON-serialized representationCodeMirror allows to serialize editor state to JSON representation with toJSON function for persistency or other needs. This JSON representation can be later used to recreate ReactCodeMirror component with the same internal state.
For example, this is how undo history can be saved in the local storage, so that it remains after the page reloads
import CodeMirror from '@uiw/react-codemirror';
import { historyField } from '@codemirror/commands';
// When custom fields should be serialized, you can pass them in as an object mapping property names to fields.
// See [toJSON](https://codemirror.net/docs/ref/#state.EditorState.toJSON) documentation for more details
const stateFields = { history: historyField };
export function EditorWithInitialState() {
const serializedState = localStorage.getItem('myEditorState');
const value = localStorage.getItem('myValue') || '';
return (
<CodeMirror
value={value}
initialState={
serializedState
? {
json: JSON.parse(serializedState || ''),
fields: stateFields,
}
: undefined
}
onChange={(value, viewUpdate) => {
localStorage.setItem('myValue', value);
const state = viewUpdate.state.toJSON(stateFields);
localStorage.setItem('myEditorState', JSON.stringify(state));
}}
/>

In this article, we’ll discuss how to use jQuery Ajax for ASP.NET Core MVC CRUD Operations using Bootstrap Modal. With jQuery Ajax, we can make HTTP request to controller action methods without reloading the entire page, like a single page application.
To demonstrate CRUD operations – insert, update, delete and retrieve, the project will be dealing with details of a normal bank transaction. GitHub repository for this demo project : https://bit.ly/33KTJAu.
Sub-topics discussed :
In Visual Studio 2019, Go to File > New > Project (Ctrl + Shift + N).
From new project window, Select Asp.Net Core Web Application_._
Once you provide the project name and location. Select Web Application(Model-View-Controller) and uncheck HTTPS Configuration. Above steps will create a brand new ASP.NET Core MVC project.
Let’s create a database for this application using Entity Framework Core. For that we’ve to install corresponding NuGet Packages. Right click on project from solution explorer, select Manage NuGet Packages_,_ From browse tab, install following 3 packages.
Now let’s define DB model class file – /Models/TransactionModel.cs.
public class TransactionModel
{
[Key]
public int TransactionId { get; set; }
[Column(TypeName ="nvarchar(12)")]
[DisplayName("Account Number")]
[Required(ErrorMessage ="This Field is required.")]
[MaxLength(12,ErrorMessage ="Maximum 12 characters only")]
public string AccountNumber { get; set; }
[Column(TypeName ="nvarchar(100)")]
[DisplayName("Beneficiary Name")]
[Required(ErrorMessage = "This Field is required.")]
public string BeneficiaryName { get; set; }
[Column(TypeName ="nvarchar(100)")]
[DisplayName("Bank Name")]
[Required(ErrorMessage = "This Field is required.")]
public string BankName { get; set; }
[Column(TypeName ="nvarchar(11)")]
[DisplayName("SWIFT Code")]
[Required(ErrorMessage = "This Field is required.")]
[MaxLength(11)]
public string SWIFTCode { get; set; }
[DisplayName("Amount")]
[Required(ErrorMessage = "This Field is required.")]
public int Amount { get; set; }
[DisplayFormat(DataFormatString = "{0:MM/dd/yyyy}")]
public DateTime Date { get; set; }
}
C#Copy
Here we’ve defined model properties for the transaction with proper validation. Now let’s define DbContextclass for EF Core.
#asp.net core article #asp.net core #add loading spinner in asp.net core #asp.net core crud without reloading #asp.net core jquery ajax form #asp.net core modal dialog #asp.net core mvc crud using jquery ajax #asp.net core mvc with jquery and ajax #asp.net core popup window #bootstrap modal popup in asp.net core mvc. bootstrap modal popup in asp.net core #delete and viewall in asp.net core #jquery ajax - insert #jquery ajax form post #modal popup dialog in asp.net core #no direct access action method #update #validation in modal popup

User registration and authentication are mandatory in any application when you have little concern about privacy. Hence all most all application development starts with an authentication module. In this article, we will discuss the quickest way to use **ASP.NET Core Identity for User Login and Registration **in a new or existing MVC application.
Sub-topics discussed :
ASP.NET Core Identity is an API, which provides both user interface(UI) and functions for user authentication, registration, authorization, etc. Modules/ APIs like this will really be helpful and fasten the development process. It comes with ASP.NET Core Framework and used in many applications before. Which makes the API more dependable and trustworthy.
ASP.NET Core MVC with user authentication can easily be accomplished using Identity.UI. While creating the MVC project, you just need to select Authentication as Individual User Accounts.
The rest will be handled by ASP.NET Core Identity UI. It already contains razor view pages and backend codes for an authentication system. But that’s not what we want in most of the cases. we want to customize ASP.NET Core Identity as per our requirement. That’s what we do here.
First of all, I will create a brand new ASP.NET Core MVC application without any authentication selected. We could add ASP.NET Core Identity later into the project.
In Visual Studio 2019, Go to File > New > Project (Ctrl + Shift + N). From new project window, select ASP.NET Core Web Application.
Once you provide the project name and location. A new window will be opened as follows, Select _Web Application(Model-View-Controller), _uncheck _HTTPS Configuration _and DO NOT select any authentication method. Above steps will create a brand new ASP.NET Core MVC project.
