Imagine you're developing an ASP.NET Core application on a machine without any internet access. Which tool, among the following, allows you to install NuGet packages from a local feed or folder?
- Visual Studio Code
- NuGet Package Manager Console
- .NET CLI
- NuGet CLI
When working on a machine without internet access, you can use the NuGet CLI to install NuGet packages from a local feed or folder. The NuGet CLI provides command-line tools for interacting with NuGet packages, making it a suitable choice for such scenarios.
While learning about Razor views, you come across a file that seems to determine the layout for all views. What is the typical name of this file?
- _Layout.cshtml
- View.cshtml
- MainLayout.cshtml
- MasterPage.cshtml
The typical name of the file that determines the layout for all views in ASP.NET Core is "_Layout.cshtml." It serves as the master layout template for your application, defining the structure that other views follow.
Application-specific settings, such as connection strings, can be added to the ________ file.
- AppSettings.json
- Startup.cs
- Program.cs
- Controller.cs
Application-specific settings, including connection strings, are commonly stored in the "AppSettings.json" file in ASP.NET Core applications. This JSON configuration file allows developers to manage various application settings in a structured manner.
When dealing with complex forms in Razor, which approach allows for grouping related form fields into smaller, reusable views?
- Partial Views
- Layout Views
- Model Binding
- Tag Helpers
When dealing with complex forms in Razor, using Partial Views is a common approach. Partial Views allow you to create modular and reusable components for form fields. This helps in organizing and maintaining complex forms by breaking them down into smaller, manageable parts.
The _________ tool in ASP.NET Core is particularly useful for tasks like building the application, running migrations, or scaffolding items.
- .NET CLI
- Entity Framework
- MSBuild
- Visual Studio
The .NET CLI (Command Line Interface) in ASP.NET Core is a powerful tool for various development tasks. It allows developers to build, test, run, and manage ASP.NET Core applications from the command line. Tasks such as building the application, running database migrations, or scaffolding code can be efficiently accomplished using the .NET CLI.
What command would you typically use to create a new ASP.NET Core web application using the .NET Core CLI?
- dotnet new web
- dotnet build
- dotnet run
- dotnet publish
The correct command to create a new ASP.NET Core web application using the .NET Core CLI is dotnet new web. This command sets up a basic web application template for you to start building upon.
When creating custom Razor tag helpers, the method _________ is overridden to generate the desired output.
- Process
- Execute
- Generate
- Handle
When creating custom Razor tag helpers in ASP.NET Core, you override the "Execute" method to generate the desired HTML output. This method is called when the tag helper is encountered in a Razor view, allowing you to customize the generated content.
The _______ directive in _ViewImports.cshtml is used to include a namespace across multiple Razor views.
- @using
- @model
- @section
- @namespace
In ASP.NET Core Razor views, the @using directive is used to include a namespace that can be accessed across multiple views. This is useful for making classes, methods, or extensions from the namespace available in your views.
You're noticing that despite having global exception handling set up in your ASP.NET Core application, certain exceptions aren't being caught. What might be a plausible reason for this behavior and how can you ensure all exceptions are captured?
- Some exceptions may occur before the middleware pipeline
- Certain exceptions bypass the UseExceptionHandler middleware
- Exception filters are causing conflicts
- There is a bug in the .NET Core runtime
In ASP.NET Core, some exceptions, such as those occurring early in the middleware pipeline, may bypass the UseExceptionHandler middleware. These include exceptions during routing and model binding. To ensure all exceptions are captured, consider using other middleware or filters to catch exceptions at different stages of the request pipeline.
What is the significance of the MapFallbackTo method in endpoint routing?
- It defines a catch-all route for unmatched requests
- It maps routes to multiple controllers
- It handles exceptions in the routing process
- It defines route constraints
The MapFallbackTo method in endpoint routing is significant as it allows developers to define a catch-all route for unmatched requests. This route is used when no other routes match the incoming request, enabling developers to implement custom error handling or redirect logic for such cases.
