Bundling and minification improves the speed and rendering performance of any web application. Bundling combines multiple JavaScript or CSS files into a single file where Minification reduces the size of the JavaScript or CSS file by removing white space and commented code without altering functionality. This not only reduces the number of requests to the server, also reduces the size of data transfer from the server to the browser. Both the techniques when used together can help in improving the performance of your web app. Bundling and minification can be done at design time and also at runtime. This post talks about 6 tools for bundling and minification in ASP.NET Core. Read More

Add Swagger to ASP.NET Core 2.0 Web API
Testing WEB APIs is a challenge, and it has a dependency on various third-party tools for proper and efficient testing. But swagger can make it easy. Swagger is an UI representation of your RESTful API. Swagger UI allows anyone — be it your development team or your end consumers — to visualize and interact with the API’s resources having none of the implementation logic in place. It’s automatically generated from your Swagger specification, with the visual documentation, making it easy for back-end implementation and client-side consumption. Earlier, I posted about adding swagger with ASP.NET Core but it no longer works with ASP.NET Core 2.0 due to new changes with ASP.NET Core 2.0. In this post, we’ll see how to add Swagger to ASP.NET Core 2.0 Web API. Read More
Import and Export excel in ASP.NET Core 2.0 Razor Pages
Last year around this time I wrote about Import and Export xlsx in ASP.NET Core, using an unofficial version of EPPlus.Core as EPPlus didn’t have .NET core support.

When .NET Standards came, the situation improved a bit, but the release of .NET Standards 2.0 was a booster for .NET Core as that helped to port existing .NET Framework based libraries to use with .NET Core.
NPOI is another very popular package for reading/writing excel files, and it also has .NET core version as well. This post talks about how to import or export excel files (xls or xlsx) using NPOI package with ASP.NET Core 2.0 Razor pages. Read More
