"wwwroot/js/site.js"
],
"minify": {
"enabled": true
}
}
]
Integrate with the Build Process
Add instructions to execute the bundling and minification operations during the build process in your project file (.csproj).
Add the following element inside the <Project>
element in your .csproj file:
<Target Name="PrepublishScript" BeforeTargets="PrepareForPublish">
<Exec Command="dotnet bundle" />
</Target>
<Target Name="PrepublishScript" BeforeTargets="PrepareForPublish">
<Exec Command="dotnet bundle" />
</Target>
Install and Run BundlerMinifier
To use the BundlerMinifier tool, you must install the .NET utility. Execute the following command:
dotnet tool install -g BundlerMinifier.Core
dotnet tool install -g BundlerMinifier.Core
To bundle and minify your files, run:
dotnet bundle
dotnet bundle
Optimize Images
You can use ImageSharp or other .NET Core-compliant image optimization tools for image optimization.
Install ImageSharp
Install the SixLabors.ImageSharp package:
dotnet add package SixLabors.ImageSharp
dotnet add package SixLabors.ImageSharp
Here is an example of a code snippet for image optimization:
using SixLabors.ImageSharp;
using SixLabors.ImageSharp.Processing;
using System.IO;
public void OptimizeImage(string inputPath, string outputPath)
{
// Load the image
using (var image = Image.Load(inputPath))
{
// Resize and optimize the image
image.Mutate(x => x.Resize(new ResizeOptions
{
Mode = ResizeMode.Max,
Size = new Size(800, 600)
}));
// Save the image in an optimized format
image.Save(outputPath); // Automatic encoder selected based on file extension.
}
}
using SixLabors.ImageSharp;
using SixLabors.ImageSharp.Processing;
using System.IO;
public void OptimizeImage(string inputPath, string outputPath)
{
// Load the image
using (var image = Image.Load(inputPath))
{
// Resize and optimize the image
image.Mutate(x => x.Resize(new ResizeOptions
{
Mode = ResizeMode.Max,
Size = new Size(800, 600)
}));
// Save the image in an optimized format
image.Save(outputPath); // Automatic encoder selected based on file extension.
}
}
Imports SixLabors.ImageSharp
Imports SixLabors.ImageSharp.Processing
Imports System.IO
Public Sub OptimizeImage(ByVal inputPath As String, ByVal outputPath As String)
' Load the image
Using image = System.Drawing.Image.Load(inputPath)
' Resize and optimize the image
image.Mutate(Function(x) x.Resize(New ResizeOptions With {
.Mode = ResizeMode.Max,
.Size = New Size(800, 600)
}))
' Save the image in an optimized format
image.Save(outputPath) ' Automatic encoder selected based on file extension.
End Using
End Sub
Run your application to ensure bundling and minification are operating as intended. Open your application in the browser, then verify that the JavaScript and CSS files are minified.

Configure Bundling and Minification
Ensure that the bundleconfig.json
config file is in place to provide the bundling and minification settings again as needed:
[
{
"outputFileName": "wwwroot/css/site.min.css",
"inputFiles": [
"wwwroot/css/site.css"
],
"minify": {
"enabled": true,
"renameLocals": true
}
},
{
"outputFileName": "wwwroot/js/site.min.js",
"inputFiles": [
"wwwroot/js/site.js"
],
"minify": {
"enabled": true
}
}
]
Connect to the Building Process
Ensure that your .csproj file contains instructions for executing the minification and bundling operations during the build process. Add the following Target within the <Project>
element:
<Target Name="PrepublishScript" BeforeTargets="PrepareForPublish">
<Exec Command="dotnet bundle" />
</Target>
<Target Name="PrepublishScript" BeforeTargets="PrepareForPublish">
<Exec Command="dotnet bundle" />
</Target>
Integrate IronPDF
Build a controller with IronPDF to produce PDFs. Create a new PdfController controller.
using Microsoft.AspNetCore.Mvc;
using IronPdf;
namespace WebGreaseIronPdfApp.Controllers
{
public class PdfController : Controller
{
public IActionResult GeneratePdf()
{
// Create a PDF from a simple HTML string
var renderer = new ChromePdfRenderer();
var pdf = renderer.RenderHtmlAsPdf("<h1>Hello, IronPDF!</h1><p>This is a generated PDF document.</p>");
// Save the PDF to a byte array
var pdfBytes = pdf.BinaryData;
// Return the PDF file as a download
return File(pdfBytes, "application/pdf", "example.pdf");
}
}
}
using Microsoft.AspNetCore.Mvc;
using IronPdf;
namespace WebGreaseIronPdfApp.Controllers
{
public class PdfController : Controller
{
public IActionResult GeneratePdf()
{
// Create a PDF from a simple HTML string
var renderer = new ChromePdfRenderer();
var pdf = renderer.RenderHtmlAsPdf("<h1>Hello, IronPDF!</h1><p>This is a generated PDF document.</p>");
// Save the PDF to a byte array
var pdfBytes = pdf.BinaryData;
// Return the PDF file as a download
return File(pdfBytes, "application/pdf", "example.pdf");
}
}
}
Imports Microsoft.AspNetCore.Mvc
Imports IronPdf
Namespace WebGreaseIronPdfApp.Controllers
Public Class PdfController
Inherits Controller
Public Function GeneratePdf() As IActionResult
' Create a PDF from a simple HTML string
Dim renderer = New ChromePdfRenderer()
Dim pdf = renderer.RenderHtmlAsPdf("<h1>Hello, IronPDF!</h1><p>This is a generated PDF document.</p>")
' Save the PDF to a byte array
Dim pdfBytes = pdf.BinaryData
' Return the PDF file as a download
Return File(pdfBytes, "application/pdf", "example.pdf")
End Function
End Class
End Namespace
The first thing we do in the PdfController code is import the required namespaces, which are Microsoft.AspNetCore.Mvc for ASP.NET Core MVC functionality and IronPDF for PDF generation. Because it derives from Controller, the PdfController class is an MVC controller. The GeneratePdf
method in this class is defined to manage the creation of PDFs.
To convert HTML material into a PDF, this function creates an instance of IronPDF's ChromePdfRenderer
. A basic HTML string can be transformed into a PDF document using the RenderHtmlAsPdf
function. The BinaryData
attribute is then used to save this PDF to a byte array. Lastly, the PDF file is returned as a downloadable response using the File
method, along with the requested filename (example.pdf
) and the correct MIME type (application/pdf
). The program can now dynamically create and serve PDF documents based on HTML content thanks to this integration.
Route to Generate PDF
Make sure that the PDF generation routing is included in your Startup.cs
file.
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
else
{
app.UseExceptionHandler("/Home/Error");
app.UseHsts();
}
app.UseHttpsRedirection();
app.UseStaticFiles();
app.UseRouting();
app.UseAuthorization();
app.UseEndpoints(endpoints =>
{
endpoints.MapControllerRoute(
name: "default",
pattern: "{controller=Home}/{action=Index}/{id?}");
endpoints.MapControllerRoute(
name: "pdf",
pattern: "pdf",
defaults: new { controller = "Pdf", action = "GeneratePdf" });
});
}
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
else
{
app.UseExceptionHandler("/Home/Error");
app.UseHsts();
}
app.UseHttpsRedirection();
app.UseStaticFiles();
app.UseRouting();
app.UseAuthorization();
app.UseEndpoints(endpoints =>
{
endpoints.MapControllerRoute(
name: "default",
pattern: "{controller=Home}/{action=Index}/{id?}");
endpoints.MapControllerRoute(
name: "pdf",
pattern: "pdf",
defaults: new { controller = "Pdf", action = "GeneratePdf" });
});
}
