How to Migrate from TallComponents to IronPDF in C#

Curtis Chau

Updated:

When Apryse acquired TallComponents, the .NET PDF landscape changed significantly. With TallComponents no longer available for new licenses and existing users being redirected to iText SDK, developers using TallPDF and PDFKit face an unavoidable decision: migrate now or risk running unsupported software with known rendering bugs into 2026 and beyond.

This guide provides a complete migration path from TallComponents to IronPDF, including step-by-step instructions, API mappings, and real code examples to help professional .NET developers transition efficiently.

Why TallComponents Migration Is Now Mandatory

TallComponents was once a respected name in C# PDF generation. The library offered XML-based document workflows and programmatic PDF manipulation. However, the acquisition by Apryse brought an end to new license sales, fundamentally changing the calculus for development teams.

Critical TallComponents Limitations

The decision to migrate isn't just about vendor support—TallComponents carries significant technical debt:

Product Discontinuation: No new licenses are available since the Apryse acquisition. The official TallComponents website explicitly states that new license sales have ended, directing potential users to adopt iText SDK instead.

No HTML-to-PDF Support: Unlike modern PDF libraries, TallComponents does not support direct HTML to PDF conversions. Developers on support platforms have confirmed this limitation, pointing to third-party solutions like Pechkin as alternatives.

Documented Rendering Bugs: Changelogs reveal extensive rendering issues including blank page rendering, missing graphics, unreliable JPEG image handling, and incorrect font display. These bugs were never resolved before discontinuation.

No Support or Updates: Without active maintenance, any security vulnerabilities or compatibility issues with .NET 10 and C# 14 will remain unaddressed.

IronPDF: A Modern TallComponents Alternative

IronPDF addresses the core limitations that made TallComponents problematic for modern development workflows:

Feature TallComponents IronPDF
Current Sale Status Discontinued for New Sales Actively Developed and Sold
HTML-to-PDF Support No Yes (HTML5/CSS3 with Chromium)
Rendering Fidelity Known Bugs and Issues Proven Reliability
Installation Complex, Manual Simple with NuGet
Customer Support Transition to iText SDK Active Support and Community
Future Usability End-of-life Long-term Viability

The contrast is stark: TallComponents offers an XML-based approach from a different era of .NET development, while IronPDF provides Chromium-powered HTML rendering that aligns with how developers build applications today.

Quick Start: TallComponents to IronPDF Migration

Step 1: Replace NuGet Packages

Remove all TallComponents packages from your project:

# Remove TallComponents packages
dotnet remove package TallComponents.PDF.Kit
dotnet remove package TallComponents.PDF.Layout
dotnet remove package TallComponents.PDF.Layout.Drawing
# Remove TallComponents packages
dotnet remove package TallComponents.PDF.Kit
dotnet remove package TallComponents.PDF.Layout
dotnet remove package TallComponents.PDF.Layout.Drawing
SHELL

Install IronPDF:

# Install IronPDF
dotnet add package IronPdf
# Install IronPDF
dotnet add package IronPdf
SHELL

For specialized frameworks, IronPDF offers dedicated extension packages:

Blazor Server:

PM > Install-Package IronPdf.Extensions.Blazor
PM > Install-Package IronPdf.Extensions.Blazor
SHELL

MAUI:

PM > Install-Package IronPdf.Extensions.Maui
PM > Install-Package IronPdf.Extensions.Maui
SHELL

MVC Framework:

PM > Install-Package IronPdf.Extensions.Mvc.Framework
PM > Install-Package IronPdf.Extensions.Mvc.Framework
SHELL

Step 2: Update Namespaces

Replace TallComponents namespaces with the IronPdf namespace:

// Before (TallComponents)
using TallComponents.PDF.Kit;
using TallComponents.PDF.Layout;
using TallComponents.PDF.Layout.Drawing;
using TallComponents.PDF.Layout.Paragraphs;

// After (IronPDF)
using IronPdf;
// Before (TallComponents)
using TallComponents.PDF.Kit;
using TallComponents.PDF.Layout;
using TallComponents.PDF.Layout.Drawing;
using TallComponents.PDF.Layout.Paragraphs;

// After (IronPDF)
using IronPdf;
Imports IronPdf

Step 3: Initialize Your License

Add license initialization at application startup:

IronPdf.License.LicenseKey = "YOUR-LICENSE-KEY";
IronPdf.License.LicenseKey = "YOUR-LICENSE-KEY";
IronPdf.License.LicenseKey = "YOUR-LICENSE-KEY"

Code Migration Examples

Converting HTML to PDF

TallComponents lacks native HTML-to-PDF support. The workaround involves creating fragments from text, which doesn't actually render HTML:

TallComponents Approach:

// NuGet: Install-Package TallComponents.PDF.Kit
using TallComponents.PDF.Kit;
using System.IO;

class Program
{
    static void Main()
    {
        // Create a new document
        using (Document document = new Document())
        {
            string html = "<html><body><h1>Hello World</h1><p>This is a PDF from HTML.</p></body></html>";

            // Create HTML fragment
            Fragment fragment = Fragment.FromText(html);

            // Add to document
            Section section = document.Sections.Add();
            section.Fragments.Add(fragment);

            // Save to file
            using (FileStream fs = new FileStream("output.pdf", FileMode.Create))
            {
                document.Write(fs);
            }
        }
    }
}
// NuGet: Install-Package TallComponents.PDF.Kit
using TallComponents.PDF.Kit;
using System.IO;

class Program
{
    static void Main()
    {
        // Create a new document
        using (Document document = new Document())
        {
            string html = "<html><body><h1>Hello World</h1><p>This is a PDF from HTML.</p></body></html>";

            // Create HTML fragment
            Fragment fragment = Fragment.FromText(html);

            // Add to document
            Section section = document.Sections.Add();
            section.Fragments.Add(fragment);

            // Save to file
            using (FileStream fs = new FileStream("output.pdf", FileMode.Create))
            {
                document.Write(fs);
            }
        }
    }
}
Imports TallComponents.PDF.Kit
Imports System.IO

Class Program
    Shared Sub Main()
        ' Create a new document
        Using document As New Document()
            Dim html As String = "<html><body><h1>Hello World</h1><p>This is a PDF from HTML.</p></body></html>"

            ' Create HTML fragment
            Dim fragment As Fragment = Fragment.FromText(html)

            ' Add to document
            Dim section As Section = document.Sections.Add()
            section.Fragments.Add(fragment)

            ' Save to file
            Using fs As New FileStream("output.pdf", FileMode.Create)
                document.Write(fs)
            End Using
        End Using
    End Sub
End Class

IronPDF Approach:

// NuGet: Install-Package IronPdf
using IronPdf;

class Program
{
    static void Main()
    {
        // Create a PDF from HTML string
        var renderer = new ChromePdfRenderer();
        string html = "<html><body><h1>Hello World</h1><p>This is a PDF from HTML.</p></body></html>";

        var pdf = renderer.RenderHtmlAsPdf(html);
        pdf.SaveAs("output.pdf");
    }
}
// NuGet: Install-Package IronPdf
using IronPdf;

class Program
{
    static void Main()
    {
        // Create a PDF from HTML string
        var renderer = new ChromePdfRenderer();
        string html = "<html><body><h1>Hello World</h1><p>This is a PDF from HTML.</p></body></html>";

        var pdf = renderer.RenderHtmlAsPdf(html);
        pdf.SaveAs("output.pdf");
    }
}
Imports IronPdf

Class Program
    Shared Sub Main()
        ' Create a PDF from HTML string
        Dim renderer As New ChromePdfRenderer()
        Dim html As String = "<html><body><h1>Hello World</h1><p>This is a PDF from HTML.</p></body></html>"

        Dim pdf = renderer.RenderHtmlAsPdf(html)
        pdf.SaveAs("output.pdf")
    End Sub

        {
            // Iterate through pages
            foreach (Page page in document.Pages)
            {
                // Create watermark text
                TextShape watermark = new TextShape();
                watermark.Text = "CONFIDENTIAL";

IronPDF Approach:

using IronPdf;
using IronPdf.Signing;

var pdf = PdfDocument.FromFile("unsigned.pdf");

// Sign with certificate
var signature = new PdfSignature("certificate.pfx", "password")
{
    SigningContact = "support@company.com",
    SigningLocation = "New York",
    SigningReason = "Document Approval"
};

pdf.Sign(signature);
pdf.SaveAs("signed.pdf");
using IronPdf;
using IronPdf.Signing;

var pdf = PdfDocument.FromFile("unsigned.pdf");

// Sign with certificate
var signature = new PdfSignature("certificate.pfx", "password")
{
    SigningContact = "support@company.com",
    SigningLocation = "New York",
    SigningReason = "Document Approval"
};

pdf.Sign(signature);
pdf.SaveAs("signed.pdf");
Imports IronPdf
Imports IronPdf.Signing

Dim pdf = PdfDocument.FromFile("unsigned.pdf")

' Sign with certificate
Dim signature = New PdfSignature("certificate.pfx", "password") With {
    .SigningContact = "support@company.com",
    .SigningLocation = "New York",
    .SigningReason = "Document Approval"
}

pdf.Sign(signature)
pdf.SaveAs("signed.pdf")

TallComponents Migration Checklist

Pre-Migration Tasks

Audit your codebase to identify all TallComponents usage:

grep -r "using TallComponents" --include="*.cs" .
grep -r "Document\|Section\|TextParagraph" --include="*.cs" .
grep -r "using TallComponents" --include="*.cs" .
grep -r "Document\|Section\|TextParagraph" --include="*.cs" .
SHELL

Document existing XML templates and layouts—these will be converted to HTML. Identify security settings currently in use, noting password configurations and digital signature implementations.

Code Update Tasks

  1. Remove TallComponents packages via NuGet
  2. Install IronPdf package
  3. Convert XML layouts to HTML templates
  4. Replace Section/Paragraph model with HTML elements
  5. Update table code to use standard HTML tables
  6. Convert headers/footers to HTML with HtmlHeaderFooter
  7. Update security settings to use pdf.SecuritySettings
  8. Add license initialization at startup

Headers and Footers Migration

TallComponents uses XML-based headers. IronPDF provides HTML-based headers with dynamic placeholders:

renderer.RenderingOptions.HtmlHeader = new HtmlHeaderFooter()
{
    HtmlFragment = "<div style='text-align:center;'>Header Text</div>",
    MaxHeight = 25
};
renderer.RenderingOptions.HtmlFooter = new HtmlHeaderFooter()
{
    HtmlFragment = "<div style='text-align:center;'>Footer Text</div>",
    MaxHeight = 25
};
renderer.RenderingOptions.HtmlHeader = new HtmlHeaderFooter()
{
    HtmlFragment = "<div style='text-align:center;'>Header Text</div>",
    MaxHeight = 25
};
renderer.RenderingOptions.HtmlFooter = new HtmlHeaderFooter()
{
    HtmlFragment = "<div style='text-align:center;'>Footer Text</div>",
    MaxHeight = 25
};
Imports System

renderer.RenderingOptions.HtmlHeader = New HtmlHeaderFooter() With {
    .HtmlFragment = "<div style='text-align:center;'>Header Text</div>",
    .MaxHeight = 25
}
renderer.RenderingOptions.HtmlFooter = New HtmlHeaderFooter() With {
    .HtmlFragment = "<div style='text-align:center;'>Footer Text</div>",
    .MaxHeight = 25
}

Testing Phase

  1. Compare visual output between TallComponents and IronPDF versions
  2. Verify blank page issues are resolved
  3. Test all document templates
  4. Validate PDF merging functionality
  5. Test digital signatures
  6. Confirm security settings apply correctly

Given that TallComponents is discontinued with no support, the migration should proceed urgently:

Week 1: Audit codebase and identify all TallComponents usage
Week 2: Convert document templates from XML to HTML
Week 3: Update security, merging, and signing code
Week 4: Testing and production deployment

Delaying means running unsupported software with documented rendering bugs—a risk no professional development team should accept heading into 2026.

Key Migration Benefits

Moving from TallComponents to IronPDF provides immediate advantages:

Modern Chromium Rendering Engine: Full CSS and JavaScript support ensures PDFs render exactly as expected, eliminating the blank page and missing graphics bugs documented in TallComponents.

Active Maintenance and Security Updates: IronPDF receives regular updates, ensuring compatibility with current and future .NET versions including .NET 10.

Better .NET Integration: Native async/await support and modern API patterns align with contemporary C# development practices.

Comprehensive Documentation: Extensive tutorials and API references support rapid implementation.
