Use case of .http files in Visual Studio
An API .http file a feature provided by Visual Studio 2022 for testing ASP.NET Core projects. This serves as a convenient way to send HTTP requests and view responses directly within the Visual Studio IDE.
Further more, the VS 2022 .http file editor allows you to define HTTP requests that you want to send to test API endpoints.
It comes with an easy way to specify the details of HTTP requests including
- URL
- HTTP method (GET, POST, PUT.,DELETE)
- headers,
- query parameters
- request body
After completion of the a request, Visual Studio IDE displays the response directly within the editor itself, allowing an easy way to view the response status code, headers, and body.

Auto Generate .gitignore file
This is a configuration file that tells Git what to ignore when committing changes to Git based repositories (the ones in GitHub).
The .gitignore file controls what files to ignore when committing changes to Git repositories. The good new is is there is a tool called gitignore.io. This tool will generate such files for us.
I like this as it allows to type programming languages/platforms and generates the file for us

C# download file from a given URL
If you want to download a file in C # form a given url following code snippet can be used.
public static async Task Download(string remoteUri, string directory)
{
try
{
string filePath = Path.Combine(directory, Path.GetFileName(remoteUri));
var httpClient = new HttpClient();
if (!Directory.Exists(directory))
{
Directory.CreateDirectory(directory);
}
using var stream = await httpClient.GetStreamAsync(remoteUri);
using var fileStream = new FileStream(filePath, FileMode.Create);
await stream.CopyToAsync(fileStream);
}
catch (Exception)
{
throw;
}
}
When calling the above method we can user as
Download("https://abc.com/Content/Images/imagename.jpg", Directory.GetCurrentDirectory() + "\\images\\").Wait();
Note that this code is compatible with .Net 6 and .Net 7.
