Add-Migration : Cannot bind argument to parameter 'Path' because it is null - Entity Framework Core Error

-
Good morning!

Recently, I've been reading some tutorials on .NET Core specifically Entity Framework Core and doing some basic coding of the Code First Paradigm using a Console Application. However, running the first command Add-Migration "Migration Name" to enable migrations for the application produced an error "Unable to resolve startup project ''. Using project 'ConsoleDemoEF' as the startup project. Add-Migration : Cannot bind argument to parameter 'Path' because it is null". The full details of the issue is provided below. 
PM> Add-Migration InitialTestMigration
Unable to resolve startup project ''.
Using project 'ConsoleDemoEF' as the startup project.
Add-Migration : Cannot bind argument to parameter 'Path' because it is null.

+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidData: (:) [Add-Migration], ParameterBindingValidationException
    + FullyQualifiedErrorId : ParameterArgumentValidationErrorNullNotAllowed,Add-Migration
I've spent a couple of hours looking for answers but to no avail most of the presented solutions did not solve the issue. The Console App's specifications are as follows: Target Framework - .NET Core 2.1, Microsoft.EntityFrameworkCore.SqlServer 2.1.0 and Microsoft.EntityFrameworkCore.Tools 2.1.0. I did try all of the 2.x versions with matching EF Core packages.

After several attempts, I made the Add-Migrations commmand work by creating another Console application that targets the .NET Core 3.1 Framework and selected the latest version of Microsoft.EntityFrameworkCore.SqlServer and Microsoft.EntityFrameworkCore.Tools NuGet packages from 2.x to 5.0.4. After that, I can now proceed running the other commands of Entity Framework Core Code First approach such as Update-Database.

Good day to all! Here's an example of a WPF CRUD (Create,Update and Delete) project using the DataGrid control, ADO.NET Entity Framework 6.x, C#.NET and Model–View–Viewmodel(MVVM) architectural pattern. This post was based from this tutorial WPF CRUD With DataGrid, Entity Framework And C#.NET except that we are now using the MVVM framework. The steps below are pretty straightforward and easy to follow. I. Project Setup 1. Add a table called Students in you database. The complete script is found in this post WPF CRUD With DataGrid, Entity Framework And C#.NET 2. Create a WPF Project and add four folders called DataAccess, Model, View and ViewModel. 3. Your project structure may look similar with the screenshot provided below. II. Coding The Model and Repository Class 1. Inside the Model folder, add an ADO.NET Entity Data Model that connects to the Students table in your database. On my part, I named it StudentModel . 2. For the connectionstring name in App.config file, I ...

Good Day Gents! During this free-time I started setting up Node.js on my machine as part of my career goals which is learning new frameworks in preparation for new projects. So the first thing I did was to install TypeScript language to get myself familiar with Angular 2+. After I finished setting up TypeScript, I then created a simple HelloWorld program and ran the application through Visual Studio Code using the "tsc: build - tsconfig.json" command. I encountered an error which says "The term 'tsc' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again." Below are the details on my machine and packages installed:   - Operating System: Windows 10 Pro   - Node.js: 14.16.0   - npm version: 6.14.11   - Typescript: 4.2.3 (using command: "npm install -g typescript") After doing some research and reading th...

Invalid nested tag div found, expected closing tag input

-
Hello all, I've been experimenting on how to print html document using the said 3rd party software called iTextSharp . iTextSharp is a popular tool and has several examples on the internet regarding integration to the project and occurring issues. One of the issue I encountered is Invalid nested div tag and is expecting a closing tag input . As I trace back my html source, the tags are well-formed except that they are self closing tags such as <input>, <hr>, <img>, <br> or the like. These tags when passed to an action method as string are not properly closed and thus an issue is thrown by iTextSharp's XMLWorkerHelper's ParseXHtml() method. <img src= "~/Images/success.png" /> <input type= "hidden" name= "OrderStatusHTML" /> <input type= "submit" id= "btnSubmit" value= "Export to PDF" class= "btn btn-success" /> The solution I came up with is to fi...
