• Can't clone from repository of Github in Visual Studio

  Recently, my visual studio can't clone from repository of GitHub.

  Once it is completed clone, the visual studio will report this error "One or more errors occurred":

  

  I cannot find any error in the output windows in visual studio.

  And then, the Git Changes is blank. I can't pull and push any.
  

  Previously I considered maybe it is the problem of my Visual Studio or Operation System.

  However, after I reinstalled my Visual Studio and even reinstalled my Operation System, the problem is still here.

  Soon I found a topic may relate my problem:Git has stopped working after installing VS 2022

  Whereas, I tried all the ways in it and it doesn't work any.

  The version of my Visual Studio is 2022 17.1.6. What's wrong with it?

• School Project, set up OpenGL on VS 2019 Community

  I am trying to set up OpenGL on my PC for a project. The project gave me sample code to run and a folder to add include directories and libs to my sample code solution in VS 2019 community. The directions were awful and wanted me to upload the include and lib directories to VC++. This did not work even remotely, none of the glfw or glew headers were recognized. I found other directions online to upload the include folders under C/C++>General>Additional Include Directories and the libs under Link>General>Additional Lib Directories. Then I added glfw3.lib;glu32.lib;glew32.lib;opengl32.lib to my Link>Input>Additional Dependencies. This allowed my program to compile. But now I get the following errors plus 90 more like it:

  Warning LNK4098 defaultlib 'MSVCRT' conflicts with use of other libs; use /NODEFAULTLIB:library OpenGLSample    C:\OpenGL_Projects\OpenGLSample\OpenGLSample\LINK   1
  Error   LNK2019 unresolved external symbol __imp__TranslateMessage@4 referenced in function __glfwPlatformInit  OpenGLSample    C:\OpenGL_Projects\OpenGLSample\OpenGLSample\glfw3.lib(win32_init.obj)  1```
  
• NUnit Test case

  using System;
  using System.Collections.Generic ;
  using System.Linq;
  using System. Text;
  using System. Threading. Tasks;
  
  namespace DemoAppCore{
  
  public class Program
  {

  }
  }
  public class Employee
  {
  public string Name { get; set; }
  public string Id { get; set; }
  }
  

  Please anyone help me to write a C# NUnit Test case for this program.I tried many different way to solve this program but none of the test cases work. Class Program This class contains a method, 'EnrollEmployee' In this method, an object for "Employee" is created and returned.

  Class Employee This is a model class containing Name and Id property.

  Write respective test methods for the following : a) Variable "e1" is null b) On invoking method 'EnrollEmployee', the object returned is not null. c) The "Name" property is equal to "Tom" by invoking method 'EnrollEmployee' d) The "Id" property is equal to "A1234" by invoking method 'EnrollEmployee'

  Implement:

  1. Add the required test attribute for the class FunctionalTest
  2. Add the required test attribute for each test methods
  3. Wherever applicable, Assert whether the actual is equal to the expected

• Instantiation of User Controls dissapearing on InitalizeComponent() when modifiyng Form

  Hi everyone and thank you in advance. I have created a User Control named PanelOption that is a panel with a CheckBox and a TextBox, and these are inside a FlowPanelLayOut. It runs well and everything works perfectly.

  The problem comes when I modify the form where these PanelOption are. They dissapear from the InitializeComponent method as I show you below:

  private void InitializeComponent()
      {
          this.components = new System.ComponentModel.Container();
          System.ComponentModel.ComponentResourceManager resources = new System.ComponentModel.ComponentResourceManager(typeof(CrearMultipleForm));
          this.txtEnunciado = new System.Windows.Forms.TextBox();
          this.txtPuntaje = new System.Windows.Forms.TextBox();
          this.lblPuntaje = new System.Windows.Forms.Label();
          this.lbNumPreg = new System.Windows.Forms.Label();
          this.FlowPanelOpciones = new System.Windows.Forms.FlowLayoutPanel();
          this.panelOptionSM1 = new Custom_Components.PanelOption('A');
          this.panelOptionSM2 = new Custom_Components.PanelOption('C');
          this.panelOptionSM3 = new Custom_Components.PanelOption('B');
          this.panelOptionSM4 = new Custom_Components.PanelOption('D');
          this.panel2 = new System.Windows.Forms.Panel();
          this.botonMinus = new QuizifyIU.Controles_Personalizados.Boton();
          this.botonPlus = new QuizifyIU.Controles_Personalizados.Boton();
          this.btnCrear = new QuizifyIU.Controles_Personalizados.Boton();
          this.btnCancelar = new QuizifyIU.Controles_Personalizados.Boton();
          this.btnRespAbierta = new QuizifyIU.Controles_Personalizados.Boton();
          this.btnVF = new QuizifyIU.Controles_Personalizados.Boton();
          this.btnMultiple = new QuizifyIU.Controles_Personalizados.Boton();
          this.flowLayoutPanel1.SuspendLayout();
          this.panel1.SuspendLayout();
          this.FlowPanelOpciones.SuspendLayout();
          this.panel2.SuspendLayout();
          this.SuspendLayout();
  

  Here you can see the objects panelOptionSM1, panelOptionSM2... being instantiated . But as I said when I modify the form on the designer, Visual Studio removes the instantiation of the objects like this:

  private void InitializeComponent()
      {
          this.components = new System.ComponentModel.Container();
          System.ComponentModel.ComponentResourceManager resources = new System.ComponentModel.ComponentResourceManager(typeof(CrearMultipleForm));
          this.txtEnunciado = new System.Windows.Forms.TextBox();
          this.txtPuntaje = new System.Windows.Forms.TextBox();
          this.lblPuntaje = new System.Windows.Forms.Label();
          this.lbNumPreg = new System.Windows.Forms.Label();
          this.FlowPanelOpciones = new System.Windows.Forms.FlowLayoutPanel();
          this.panel2 = new System.Windows.Forms.Panel();
          this.botonMinus = new QuizifyIU.Controles_Personalizados.Boton();
          this.botonPlus = new QuizifyIU.Controles_Personalizados.Boton();
          this.btnCrear = new QuizifyIU.Controles_Personalizados.Boton();
          this.btnCancelar = new QuizifyIU.Controles_Personalizados.Boton();
          this.btnRespAbierta = new QuizifyIU.Controles_Personalizados.Boton();
          this.btnVF = new QuizifyIU.Controles_Personalizados.Boton();
          this.btnMultiple = new QuizifyIU.Controles_Personalizados.Boton();
          this.flowLayoutPanel1.SuspendLayout();
          this.panel1.SuspendLayout();
          this.FlowPanelOpciones.SuspendLayout();
          this.panel2.SuspendLayout();
          this.SuspendLayout();
  

  The funny part is that the rest of the code concerning these objects remains untouched regardless of modifying the form. The rest of the code I am refereing:

  // panelOpcionSM1
          // 
          this.panelOptionSM1.BackColor = System.Drawing.Color.Transparent;
          this.panelOptionSM1.Location = new System.Drawing.Point(3, 3);
          this.panelOptionSM1.Name = "panelOpcionSM1";
          this.panelOptionSM1.Size = new System.Drawing.Size(520, 48);
          this.panelOptionSM1.TabIndex = 110;
          // 
          // panelOpcionSM4
          // 
          this.panelOptionSM4.BackColor = System.Drawing.Color.Transparent;
          this.panelOptionSM4.Location = new System.Drawing.Point(3, 57);
          this.panelOptionSM4.Name = "panelOpcionSM4";
          this.panelOptionSM4.Size = new System.Drawing.Size(520, 48);
          this.panelOptionSM4.TabIndex = 112;
          // 
          // panelOpcionSM2
          // 
          this.panelOptionSM2.BackColor = System.Drawing.Color.Transparent;
          this.panelOptionSM2.Location = new System.Drawing.Point(3, 111);
          this.panelOptionSM2.Name = "panelOpcionSM2";
          this.panelOptionSM2.Size = new System.Drawing.Size(520, 48);
          this.panelOptionSM2.TabIndex = 111;
          // 
          // panelOpcionSM3
          // 
          this.panelOptionSM3.BackColor = System.Drawing.Color.Transparent;
          this.panelOptionSM3.Location = new System.Drawing.Point(3, 165);
          this.panelOptionSM3.Name = "panelOpcionSM3";
          this.panelOptionSM3.Size = new System.Drawing.Size(525, 48);
          this.panelOptionSM3.TabIndex = 109;
  

  And also:

  private Custom_Components.PanelOption panelOptionSM3;
      private Custom_Components.PanelOption panelOptionSM1;
      private Custom_Components.PanelOption panelOptionSM4;
      private Custom_Components.PanelOption panelOptionSM2;
  

  This only happens when I modify the form, not when I rebuild the solution or change the code of the form.
• Create XML documentation file in VS 2022:s User Interface

  Goal:
  Create XML documentation file with VS 2022 as the same in the picture below. The XML should be used for Swagger.

  Problem:
  It works in 2019 but I cannot find the same functionality in VS 2022?

  Other info:
  In VS 2019 you do this in order to create XML documentation file (https://code-maze.com/swagger-ui-asp-net-core-web-api/)
• Porting Xamarin tutorial over to .NET MAUI

  For my first ever mobile app project (which will eventually become an actual commercial project), I would like to try out .NET MAUI. Unfortunately since it's still in pre-release, there is scarce documentation and no tutorial projects for it. I did find the Xamarin tutorial here:

  https://dotnet.microsoft.com/en-us/learn/xamarin/hello-world-tutorial/intro

  ... but I don't think it's compatible with .NET MAUI.

  Are there any other places where a newbie mobile developer who knows Visual Studio and C# can see an example app and be able to learn through creating an app on the level of, say, the Contoso University web app I went through to learn ASP.NET Core with data model? Can a Xamarin tutorial be tweaked to work with .NET MAUI? If so, I would be happy to help with that process. Now that I think about it, since I developed my web site based on the Contoso model, maybe I could help create a mobile app in .NET MAUI for that Contoso project? Anyone at Microsoft interested?
• Why is NUnit ignoring tests with Combinatorial/Values attributes?

  I tried to use Combinatorial/Values attributes in NUnit.

  While it works locally, the test decorated with those attributes are skipped in TeamCity build running NUnit 2.6.2—the build report indicates that the test was ignored, without giving any details about the reason to ignore it.

  According to the documentation, Combinatorial attribute (as well as the Values attribute) exists in NUnit 2.5, and so I would expect it to still be supported in NUnit 2.6.

  Why is the test ignored?

  Here's a most basic example which reproduces the issue. Locally, both tests run and give the exact same results. On TeamCity, only Test1 is executed, and Test2 is marked as ignored.

  [TestCase("a", "1")]
  [TestCase("a", "2")]
  [TestCase("b", "1")]
  [TestCase("b", "2")]
  public void Test1(string x, string y) {
      Assert.AreEqual(x + "," + y, string.Format("{0},{1}", x, y));
  }
  
  [Test, Combinatorial]
  public void Test2([Values("a", "b")] string x, [Values("1", "2")] string y) {
      Assert.AreEqual(x + "," + y, string.Format("{0},{1}", x, y));
  }
  
• How to re-run a fail Nunit Test 2.6.2

  I am trying to Re-run failed Nunit tests, mainly because of flackiness with selenium.

      [TearDown]
      public virtual void TearDown()
      {
          var testName = TestContext.CurrentContext.Test.FullName.Replace("Server.Tests.", string.Empty);
  
          if (TestContext.CurrentContext.Result.Status == TestStatus.Passed)
              return;
          else if (_testFailure < 3) {
              _testFailure++;
              Console.WriteLine($"\n {testName} {TestContext.CurrentContext.Result.Status}... Retrying attempt {_testFailure}");
              DbReloader.LoadUnitTestData(DbFactory);
              TestExecutionContext.CurrentContext.CurrentTest.Run(new NullListener(), TestFilter.Empty);
  
          }
          BrowserDriver.GetScreenshot()
                       .SaveAsFile($"{testName}.fail.png", ImageFormat.Png);
      }
  

  The problem is after the test runs again, it will continue with the tear down of the test as the original test failed. How do I override the TestContext.CurrentContext.Result with my retried test results?
• nunit 3 tests on command line as nunit 2.6.4

  I need to be able to do this with Nunit 2.6.4. NUnit 2.6.4 doesn't have the test flag available. How can I specify a given test in NUnit 2.6.4?
