.NET GENES

Hello, I recently encountered an error when pushing some of my ASP.NET Core MVC project to github that says "Failed To Push To The Remote Repository See The Output Window For More Details" as shown on the image below. After checking the Output Window by selecting GitHub from the dropdown list, a more explicit error message appears which is " git: 'credential-manager-core' is not a git command. See 'git --help'. ". I immediately checked my Git version that appears to be Git-2.37.1-64-bit which is slightly behind the recent update Git-2.45.0-64-bit . Replacing the old Git software with the current one solved the issue. Cheers!

Hello, Here's an upgrade of the Contoso University from .NET Core 3.1 to .NET 8. The only major change that I made was seeding the data to the database. The .NET Core 3.1 version used another class to initialize data and the logic was to loop through each the array variable and then add each array element to the DBContext object. After all array records have been added to the context object, call the context's SaveChanges() method. .NET Core 3.1 Seed Data Solution public static class DbInitializer { public static void Initialize(SchoolContext context) { //context.Database.EnsureCreated(); // Look for any students. if (context.Students.Any()) { return ; // DB has been seeded } var students = new Student[] { new Student { FirstMidName = "Carson" , LastName = "Alexander" , Enro...

Good day Team! Given that you need to access the OpenFileDialog or MessageBox Dialog In Your .NET Core Class Library that is part of a solution that contains a WPF project, there's an easy hack provided by our Solutions Architect that is to hand hack the .csproj settings. First is to open the .csproj file using an editor. Inside Property Group node, add enable WPF by adding a UseWPF element with the value of true such as below. <Project Sdk= "Microsoft.NET.Sdk" > <PropertyGroup> <TargetFramework>net7.0-windows10.0.17763.0</TargetFramework> <ImplicitUsings>enable</ImplicitUsings> <Nullable>enable</Nullable> <UseWPF>true</UseWPF> </PropertyGroup> <ItemGroup> <PackageReference Include= "Company.Utilities.CompanyLibNET7" Version= "1.0.0.3" /> <PackageReference Include= "Microsoft.Extensions.DependencyInjection" Version= "7....

Good day gents! As I was about to push my docker image to Docker Hub, I was met with an error "denied: requested access to the resource is denied.". After searching the net, I found the solution that is to login your username using the command " docker login -u your_username " followed by your password using Windows Powershell. Once done logging in, push the image to the repository using docker push command "docker push your_username/dockerdemo". Reference: Docker Denied Requested Access To The Resource Cheers!

Hi all, Another issue that I encountered while learning Docker specifically build a docker image using .NET Core is the "ERROR: failed to solve: failed to compute cache key: failed to calculate checksum of ref 405e1ab5-1d6a-4b32-b558-cdcae05e5207::q4alx8yd9wbrz32p1zv7s1yg7: "/dockerdemo/dockerdemo.csproj": not found". My project is a simple ASP.NET Core Web API project. After doing some research, the solution that works for me is to cut the docker file "DockerFile" from the folder that contains the .csproj file. Then paste it to the root folder of the project that contains the solution file (.sln). Run again powershell and execute docker build command that points to the root folder of the project where the docker file is cut and pasted. That's it!

Hello Team, I started familiarizing containerization concepts using Docker in .NET Core in the event that our team will embrace the application of containerization to our certain projects in the near future. When I installed the Docker desktop, it prompted an error "Docker Desktop Requires A Newer WSL Kernel Version Issue. Update the WSL kernel by running "wsl --update" or follow instructions at https://docs.microsoft.com/windows/wsl/wsl2-kernel." The fix to this issue is either running the "wsl --update" command similar to the screenshot below. Or download and install "wsl_update_x64" package from here Linux Kernel Update Package Cheers!

Gents Good Day! There was a question on forums on why the BindingNavigator control was either missing or grayed out in Visual Studio Toolbox of which the project's target framework is .NET 5. I decided to create a C# Windows Forms application using Visual Studio 2019 that targets the .NET 5 framework and infact, the BindingNavigator control is missing. After searching the net, I found an interesting link in StackOverflow Activate missing Winforms controls in .Net Core 3.1 which is applicable to .NET Core 3.1. I applied the steps stated in the post's answer to the Windows Forms project that I created and it works. Below are the steps to do that. 1. Comment Application.SetHighDpiMode(HighDpiMode.SystemAware); code in Program.cs file. static void Main() { //Application.SetHighDpiMode(HighDpiMode.SystemAware); Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault( false ); Application.Run( new Form1()); }...

Hi All, This article is the VB.NET version of this post Getting Started With Unity IoC Container Dependency Injection In .NET Core Using Entity Framework Core ORM And SQL Server . We will create a .NET Core Console Application that will utilize the Unity IoC Container for Dependency Injection, SQL Server and Dapper ORM. Instead of using Entity Framework, I'm using Dapper ORM coz EF does not support reverse engineering in .NET Core. There are existing power tools or other solutions on how to reverse engineer a database table but for now I'll just use Dapper. I'll be using Microsoft's sample database called ContosoRetailsDw as the datasource of this tutorial. Project Setup 1. Start off by creating a Visual Basic .NET Core Console Application targetting the latest framework which is .NET 5.0 2. Add three new folders Models, Repository and UnitOfWork. These folders contain the model and DAL classes used in this project. 3. Add the following NuGet packages: Dapper O...

Good day! In this tutorial, I will demonstrate on how to create or generate PDF reports or files using DinkToPDF in .NET 5 or .NET Core Console Application. This library is a C# .NET Core wrapper for wkhtmltopdf library that uses the Webkit engine to convert HTML files or page to PDF and was developed by 'rdvojmoc Rok Dvojmoč' from Slovenia. To begin with lets start by establishing the project structure. Project Structure 1. Create a .NET 5 or .NET Core Console Application Project. 2. Add DinkToPDF and Unity packages using NuGet. 3. Copy the libwkhtmltox (dll, dylib and so) files from DinkToPDF and attach those files to your project. Make sure to set the Copy to Output Directory attribute of those files to Copy Always . Note that there are two versions for these files,32 and 64 bit. 4. Create three folders to the project and in each folder add the empty classes or interface shown in step #6. 5. Add an empty html file called ReportTemplate inside the project and set...
