ASP.NET Core

A self-contained web sample with the package bundled.

Language binding win-x86 win-x64 win-arm64 linux-x64 linux-arm64 macos

Who this is for: Teams generating PDFs inside an ASP.NET Core service.

The sample restores the bundled .nupkg from a local source, so it builds and runs with no network access.

Try it, then licence it

The download is public and needs no key. Unlicensed output carries an evaluation watermark and nothing else is restricted.

Is this the right package for you?

Best for

You generate PDF inside an ASP.NET Core service and want a worked, runnable web sample rather than a library and a blank page.

Not the right choice when

You are writing a desktop or console .NET application. The NuGet package is the same engine without the web scaffolding.

What is in the download

Generated from the packaging script, not from a description. Each row names the build output the binary came from.

The smallest complete program: create, write, close.

csharp
app.MapGet("/invoice", (string name, decimal amount) => {
    // one engine instance per request: create, build, close, delete
    using var pdf = new PdfEngine();
    pdf.CreatePDF(stream);
    // ...
    return Results.File(stream.ToArray(), "application/pdf");
});

How it deploys

Deploy as part of your application. The engine is a native dependency of the process, so the usual rules about worker recycling and concurrency apply.

Questions about this package

Do I pay a royalty for every copy I ship?

No. Every edition is royalty-free: you may redistribute the engine inside your own application to as many end users as you like, with no per-copy fee and no runtime licence for them to accept.

Does the licence need to phone home or be activated?

No. Your build verifies the key locally, in your process. There is no activation call, no deactivation, and no server for us to take down — which is why the engine works in an air-gapped network and in a container that scales to zero.

What happens when my maintenance period ends?

Nothing stops working. A key licenses any build released on or before your coverage date, forever, including in production. Maintenance decides which BUILDS the key covers, never when it expires — the engine compares against a build date and never against the clock.

What does the free download do without a key?

Everything. The download is public and unrestricted and needs no key to run; unlicensed output simply carries an evaluation watermark. Register and we send a trial key that removes it, so you can evaluate the real output before you buy.

Can we buy on a purchase order and get a VAT invoice?

Yes. Request a quote and we will price the configuration, invoice against your PO, and show the VAT treatment for your country on the quote itself rather than after checkout.

Try ASP.NET Core before you decide

Public download, no account, no card. Register only when you want the evaluation watermark gone.
