• How to generate fake data with pre-defined list for one column while use Bogus to generate random string in another column in C# EF Core?

  I have a list of 9 items and I would like to generate exact 9 records in Standard table with the values in the list for StandardName column and use Bogus to generate the random value for the Description column. Is there a quick and easy way to do it with Bogus C#?

• Deserialize an XML string with WCF

  I have a problem with deserialize an XML string into C# objects. The problem is that I the result will always be null. This is my XML string which is stored into a string variable.

• Script Bundle and Style Bundle returning 302 Not Found Error

  I'm trying to add Script and Style Bundling to a fairly old legacy WebForms application. It works great in debug mode or with BundleTable.EnableOptimizations = false.

  But when I try to enable optimizations as it should be in production, it's not actually creating the bundles so they are returning 302 Not Found errors.

  Here's my BundleConfig class

  public static void RegisterBundles(BundleCollection bundles)
  {
      bundles.IgnoreList.Clear();
  
      bundles.Add(new ScriptBundle("~/bundles/js")
      .Include("~/Scripts/jquery-{version}.js",

  BundleConfig.RegisterBundles(BundleTable.Bundles);
  

  In the of the master page:

  <asp:PlaceHolder runat="server">
      <%: Scripts.Render("~/bundles/js") %>

• Bootsrap, Required, Fontawesome, and ASP.NET webforms

  I'm trying to do something which I think should be doable, but I'm having problems with. Here are my requirements:

  • I need to check that four values on a webform form are entered.
  • I need to allow a user to submit the data on a button click.
  • The button has some text and has some fontawesome icons in it.
  • When the data is submitted, I need to turn off the button so that the user does not inadvertently click it again and submit the exact same data the second time.
  • Get the required popups from bootstrap on an insert/update of data, assuming some data has not been entered.

  I am only able to get pieces of this working. Here is what I have tried:

  • An asp:LinkButton. I can get everything but the bootstrap required popups. I found that this seems to be caused because bootstrap required looks for a button of type "submit".

  • An asp:Button. I can get everything but the fontawesome icons. I found that I can actually insert this on a jquery document ready method, but I get all kinds of asp .net security violations when I try this. I simply can't open this up.

  • A button tag with a runat="server" on it. I've tied this in with the asp.net button click event like below. Unfortunately, when I click the button, if there is a client side onclick event handler, the server side click event never gets called. I am able to style the button like a link. This is the option that seems to get me the closest. Unfortunately, I seem to be able to get the client side onclick event or the server side onserverclick event, but not both. I'm open to any and all suggestions here.

     <button type="submit" ID="btnSubmission" runat="server" 
     onserverclick="lbCaseUpdate_Click" 
     class="buttonAsLink nav-link pl-0" ><i class="fa fa-pen fa-fw"></i> Update</button>
    

  What I need is a button/link that activates the "required" display in bootstrap, contains the fontawesome icons, runs some client side javascript to somehow communicate an update is occurring, turns off the input button, and then performs the server side operation. I don't see how to get it. I'm open to any and all suggestions.

  TIA
• Spring Boot | Session Replication | Mode COOKIE

  I have a spring boot application up and running. We run it using external standalone tomcat behind LB.

  I have tried with below approach but none works.

  web.xml

              <version>2.5</version>

  But none seems to work, user gets logout as soon as request reaches another server where login request did not come.
• Spring SessionRepositoryFilter request gets redirected after successful login

  We are currently integrating spring session to address the issue on HTTP session dependency on servlet container.

  Already added or registered the spring session filter in web.xml.

  <filter>
      <filter-name>springSessionRepositoryFilter</filter-name>
      <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
  </filter>
  <filter-mapping>
      <filter-name>springSessionRepositoryFilter</filter-name>
      <url-pattern>/cbs-rs/*</url-pattern>
  </filter-mapping>
  

  And in the spring configuration, added the DefaultCookieSerializer to change the cookie name from default SESSION to JSESSIONID.

  <bean class="org.springframework.session.web.http.DefaultCookieSerializer">
      <property name="cookieName" value="JSESSIONID"/>
      <property name="cookiePath" value="/"/>
      <property name="domainNamePattern" value="^.+?\.(\w+\.[a-z]+)$"/>
  </bean>
  

  We are using form-based authentication. After successful login, it was redirected to login page. It did not route to the next REST calls.

  During debug, I have noticed that the client cookie sent and registered in the request came from the servlet container. However, since spring session intercepts the request and add their own mechanism to use spring session, updating the cookie name with the latest spring session ID value causes the next REST calls redirected.

  Please click here for the debug image

  Is this the expected behaviour of spring session? Is there some configuration which need to be setup to resolve this issue?
• Django set cookie domain to requested domain

  Our application creates sub domains for users dynamically and has logins in it.

  I am facing an issue for sessions where the cookie is assigned to domain .mywebsite.com instead I want the cookie to be assigned to the requested subdomain like user.mywebsite.com and.

  The problem is when I login to 2 subdomains as the cookie is the same, the sessions are invalid for previous one.

  Example:

  logged in to user.mywebsite.com

  logged in to user2.mywebsite.com

  navigates to user.mywebsite.com and then session gets invalid because the cookie is assigned to domain .mywebsite.com

• Setters for session scoped bean not working in RestController

  I'm trying to get the username from the session scoped bean once the user has logged in using /users/login

  I've Autowired a session scoped bean into a RestController and in one of the endpoints in the rest controller, I'm invoking a setter on the session scoped bean. But the effect of setters is not visible for requests from the same session.

  The following is my session scoped bean:

  
  import lombok.Getter;
  import lombok.Setter;
  
  import java.io.Serializable;
  
  @Getter
  @Setter
  public class SessionSpecificUserDetails implements Serializable {
  
      private String userName;
  
  }
  
  

  import lombok.Getter;
  import org.springframework.context.annotation.Bean;
  import org.springframework.context.annotation.Configuration;
  import org.springframework.web.context.annotation.SessionScope;
  
  @Getter
  @Configuration
  public class UserSessionDetailsConfiguration {
  
      @Bean
      @SessionScope
      public SessionSpecificUserDetails sessionSpecificUserDetails() {
          return new SessionSpecificUserDetails();
      }
  
  }
  

  The following is the RestController

  
  import com.course.backend.coursebackend.config.SessionSpecificUserDetails;
  import com.course.backend.coursebackend.dao.User;
  import com.course.backend.coursebackend.repository.UserRepository;
  import com.course.backend.coursebackend.utils.ResponseUtils;
  import com.course.backend.coursebackend.utils.UserUtils;
  import org.springframework.beans.factory.annotation.Autowired;
  import org.springframework.web.bind.annotation.*;
  
  import javax.validation.Valid;
  import java.util.ArrayList;
  import java.util.List;
  import java.util.Optional;
  
  @RestController
  @RequestMapping("/users")
  public class UserController {
  
      @Autowired
      UserRepository userRepository;
  
      @Autowired
      SessionSpecificUserDetails sessionSpecificUserDetails;
  
      @GetMapping("/getLoggedInUser")
      public String getLoggedInUser() {
          return sessionSpecificUserDetails.getUserName();
      }
  
      @PostMapping("/login")
      public ResponseUtils.CustomResponse login(@RequestBody User user) {
          List<User> users = getAllUsers();
          Optional<User> optionalUser = users.stream()
                  .filter(currentUser -> currentUser.getUserName().equals(user.getUserName()))
                  .findAny();
          if (optionalUser.isEmpty()) {
              return ResponseUtils.getErrorResponse(List.of("Username not found!"));
          }
          if (optionalUser.get().getPassword().equals(user.getPassword())) {
              sessionSpecificUserDetails.setUserName(user.getUserName());
              return ResponseUtils.getSuccessResponse("Login Successful!");
          }
          return ResponseUtils.getErrorResponse(List.of("Login failed due to wrong password!"));
      }
  
  }
  

  I see that spring is creating proxy for the session scoped bean. (And may be because of that my setters are not having any effect even for the same session?)

  My question is what's the correct way to use the session scoped beans in the RestController? And what's the good way to get the username for the same session across requests? I tried marking UserController also as @SessionScope but that's also not working.
• What is the relationship between IIS Express and maintaining Session State?

  I have an application that I recently upgraded to .NET 4.8. When I try to debug the application in Visual Studio, I now get this error:

  System.Web.HttpException: 'Session state can only be used when enableSessionState is set to true, either
  in a configuration file or in the Page directive. Please also make sure that
  System.Web.SessionStateModule or a custom session state module is included in the <configuration>\
  <system.web>\<httpModules> section in the application configuration.'
  

  These suggested fixes already exist in my web.config file.

  The very same application code when deployed to my local IIS and to my test server works just fine. The only difference that I can determine is that my development/local/test environments rely on IIS Express/IIS/IIS respectively.

  Does this logic make sense? If so, what is the relationship between IIS Express and Session State? How can I investiage/modify settings related specifically to how IIS Express maintains Session State?
• ServiceStack - System.Web.HttpContext.Current.Session is null

  I have legacy .net mvc application integrated with ServiceStack APIs, I need to get/set Session values from ServiceStack APIs in order to communicate with legacy system to ensure proper working. I explored multiple option available in ServiceStack doc/other material but looks like nothing is working in my case.

  enabled session feature:

  Plugins.Add(new SessionFeature());
  

  tried to use direct:

  HttpContext.Current.Session
  

  alternate way:

  var req = (HttpRequest)base.RequestContext.Get<IHttpRequest>().OriginalRequest;
  var session = req.RequestContext.HttpContext.Session;
  

  but none of them seems working.
