Configure Tor with Bridge in Ubuntu

sudo apt-get install tor

After runing tor you can see the log of the tor by

journalctl -exft Tor

If the service started without errors, look at the Tor log

sudo journalctl -b --no-pager /usr/bin/tor
sudo apt install obfs4proxy

then you should get the bridge line. for get the bridge line go to and get your bridge line.

nano /etc/tor/torrc
UseBridges 1 
ClientTransportPlugin obfs4 exec /usr/bin/obfs4proxy

Child Component Support in Blazor CSS isolation

The CSS isolation is only applied to the component level by default but you can extend it to the child component using “::deep” attribute in the CSS file. This attribute is the Blazor attribute so, it only understands and parses by the Blazor engine. When “::deep” attribute used in the CSS file, the Blazor engine also applied scope identifier to all descendants of components.


<hr />
    paragraph:: This is child component content
    div:: This is child component content
<hr />
@code {


@page "/parentcomponent"
<h3>Parent Component</h3>
    <p>paragraph:: This is Parent Component content</p>
        div:: This is parent component content
@code {


p {
    color: red
::deep div {


Add/Load Components Dynamically in ASP.NET Blazor

@page "/somepage"


  RenderFragment dynamicComponent() => builder =>
        builder.OpenComponent(0, typeof(SurveyPrompt));
        builder.AddAttribute(1, "Title", "Some title");


Get Current URL in a Blazor Component

protected override async Task OnInitializedAsync()
    NavigationManager.LocationChanged += NavigationManagerOnLocationChanged;
    // access to uri on first page load

private void NavigationManagerOnLocationChanged(object? sender, LocationChangedEventArgs e)
    // access to uri on change


Set up Automapper in ASP.NET Core

Add the main AutoMapper Package to your solution via NuGet.

Add the AutoMapper Dependency Injection Package to your solution via NuGet.

Create a new class for a mapping profile. (I made a class in the main solution directory called MappingProfile.cs and add the following code.) I’ll use a User and UserDto object as an example.

public class MappingProfile : Profile {
     public MappingProfile() {
         // Add as many of these lines as you need to map your objects
         CreateMap<User, UserDto>();
         CreateMap<UserDto, User>();

Then add the AutoMapperConfiguration in the Startup.cs as shown below:

public void ConfigureServices(IServiceCollection services) {
    // .... Ignore code before this

   // Auto Mapper Configurations
    var mapperConfig = new MapperConfiguration(mc =>
        mc.AddProfile(new MappingProfile());

    IMapper mapper = mapperConfig.CreateMapper();



To invoke the mapped object in code, do something like the following:

public class UserController : Controller {

    // Create a field to store the mapper object
    private readonly IMapper _mapper;

    // Assign the object in the constructor for dependency injection
    public UserController(IMapper mapper) {
        _mapper = mapper;

    public async Task<IActionResult> Edit(string id) {

        // Instantiate source object
        // (Get it from the database or whatever your code calls for)
        var user = await _context.Users
            .SingleOrDefaultAsync(u => u.Id == id);

        // Instantiate the mapped data transfer object
        // using the mapper you stored in the private field.
        // The type of the source object is the first type argument
        // and the type of the destination is the second.
        // Pass the source object you just instantiated above
        // as the argument to the _mapper.Map<>() method.
        var model = _mapper.Map<UserDto>(user);

        // .... Do whatever you want after that!
