Documentation / Install guides

Install .NET (source P/Invoke)

The C# and VB.NET bindings as source and prebuilt, plus both engines.

1. Get the package

The download is public and needs no key — unlicensed output carries an evaluation watermark and nothing else is restricted. The package file is windows-dotnet.zip.

Download windows-dotnet

2. Check your platform

Two separate facts per platform: whether a licence key for this package covers it, and whether the download ships an engine binary for it.

3. Install

Add include/Visual_C#/LumasPdf.cs to your project
  (or reference lib/netstandard2.0/LumasPDF.Net.dll instead -- not both)
Copy win64/LumasPdf.dll to bin/

4. Licence it

A licence is one key string, set once at startup. Buying one and installing it is covered by how licensing works; until then the engine runs fully functional with an evaluation watermark.

5. Your first PDF

The smallest complete program: create, write, close.

using LumasPdfSdk;

var pdf = LumasPdf.pdfNewPDF();
LumasPdf.pdfCreateNewPDFW(pdf, "hello.pdf");
LumasPdf.pdfAppend(pdf);
LumasPdf.pdfSetFontW(pdf, "Helvetica", LumasPdfConsts.fsNone, 24, true, TCodepage.cp1252);
LumasPdf.pdfWriteFTextW(pdf, LumasPdfConsts.taCenter, "Hello from LumasPDF");
LumasPdf.pdfEndPage(pdf);
LumasPdf.pdfCloseFile(pdf);
LumasPdf.pdfDeletePDF(pdf);
