Today, we’re releasing .NET 5.0 Preview 6. It contains a small set of new features and performance improvements. The .NET 5.0 Preview 4 post covers what we are planning to deliver with .NET 5.0. Most of the features are now in the product, but some are not yet in their final state. We expect that the release will be feature-complete with Preview 8.
NodeServices allows ASP.NET Core developers to make use of the entire NPM ecosystem, which gives rise to a huge range of possibilities.
Visual Studio 2022 Preview 1 was released recently. While normally I hold off on talking about preview releases and other items that are going to change rapidly like .NET 6, I think it is important to know what VS2022 is all about so you know what to expect in the coming months. So in this video, we are going to see VS2022 in action, we will see what the new features are, and we will talk about what this means for VS2019.
public void ConfigureServices(IServiceCollection services)
{
services.AddMvc();
services.AddNodeServices();
} public async Task<IActionResult> Add([FromServices] INodeServices nodeServices)
{
var num1 = 10;
var num2 = 20;
var result = await nodeServices.InvokeAsync<int>("AddModule.js", num1, num2);
ViewData["ResultFromNode"] = $"Result of {num1} + {num2} is {result}";
return View();
} module.exports = function(callback, num1, num2) {
var result = num1 + num2;
callback(null, result);
}; 
حال بیاییم مثالی دیگر را مرور کنیم. میخواهیم از صفحه وب درخواستی، عکسی را تهیه کنیم. بدین منظور از کتابخانه url-to-image استفاده میکنیم. برای نصب آن دستور npm install --save url-to-image را در خط فرمان تایپ میکنیم.
بعد از اتمام نصب این بسته، متدی را برای دریافت اطلاعات ارسالی این کتابخانه تدارک میبینیم.
[HttpPost]
public async Task<IActionResult> GenerateUrlPreview([FromServices] INodeServices nodeServices)
{
var url = Request.Form["Url"].ToString();
var fileName = System.IO.Path.ChangeExtension(DateTime.UtcNow.Ticks.ToString(), "jpeg");
var file = await nodeServices.InvokeAsync<string>("UrlPreviewModule.js", url, System.IO.Path.Combine("PreviewImages", fileName));
return Content($"/Home/Download?img={fileName}");
}
public IActionResult Download()
{
var image = Request.Query["img"].ToString();
var fileName = System.IO.Path.Combine("PreviewImages", image);
var isExists = System.IO.File.Exists(fileName);
if (isExists)
{
Response.Headers.Add($"Content-Disposition", "attachment; filename=\"" + image + "\"");
var bytes = System.IO.File.ReadAllBytes(fileName);
return File(bytes, "image/jpeg");
}
else
{
return NotFound();
}
} سپس متد UrlPreviewModule.js را به صورت زیر مینویسیم:
var urlToImage = require('url-to-image');
module.exports = function (callback, url, imageName) {
urlToImage(url, imageName).then(function () {
callback(null, imageName);
}).catch(function (err) {
callback(err, imageName);
});
};
سرویسهای Node به توسعه دهندگان ASP.NET Core امکان استفاده از اکوسیستم NPM را که دارای قابلیتهای فراوانی می‌باشد، میدهد.
With the release of Visual Studio 2015 came the (final) release of the Roslyn C# compiler and C# 6. This latest version of C#’s feature list seems to be…less than exciting, but it’s important to keep in mind that before Roslyn, none of these new features would have ever made it into a release. It was simply too hard to add a feature in C#, so higher impact/value features made it in while minor annoyances/enhancements would be deferred, indefinitely
npm install @ghalamborm/bootstrap4-rtl
an exciting release incorporated with plenty of library updates, a new WASM mode, more source generators, constant performance improvements, and NativeAOT support on iOS. We hope you enjoy these new features and improvements. Stay tuned for more updates as we continue our journey of making .NET better, together!
We’re excited to share all the new features and improvements in .NET 8 Preview 5! This release is a follow-up to the Preview 4 release. You’ll continue to see many more features show up with these monthly releases. .NET 6 and 7 users will want to follow this release closely since we have focused on making it a straightforward upgrade path.
