Download Demo Application
|
|
|
|
The ZIP package available for download from the link below includes an ASP.NET demo application project with complete C# source code covering all major library features.
|
|
|
|
|
|
Running the samples in the demo application that involve HTML to PDF conversion features on Linux platforms might require installing some dependency packages. The documentation includes an entire section dedicated to building, publishing and running the demo application on multiple platforms.
|
|
 |
|
NuGet Packages |
|
|
|
For Windows deployments, add a reference to the
EvoPdf.Next.Windows
NuGet package and for Linux deployments, add a reference to the
EvoPdf.Next.Linux
NuGet package.
There is also a multiplatform metapackage that references both the Windows and Linux packages,
EvoPdf.Next which is ideal when developing on one OS
and deploying to multiple runtime environments.
These NuGet packages install all the library components.
It is also possible to install only specific components.
Please see each component page for details about which NuGet package should be installed for that component.

 |
|
Installation |
|
|
|
The HTML to PDF Converter component uses a platform specific runtime.
On Windows platforms, the runtime generally does not require the installation of additional dependencies.
On Linux platforms installing some dependency packages might be necessary, depending on the exact version of Linux you are using.
In online documentation in
the Getting Started and Publish guides you can find instructions about Linux dependencies installation on a variety of Linux platforms.
The other components of the EvoPdf Next library don’t generally require the installation of additional dependencies.
