actually i tried it on another developer machine (i'm working on a desktop application) and installed the same jsreport.Local and Binary NuGet packages..

I tried to run the same report on a machine without node.js installed and with windows defender disabled, i had the same issue.
I tried to delete the jsreport folder and run the project again several times but with the same result.. the extracted jsreport.exe is 0 bytes.

Are we sure node.js is not a requirement for jsreport local?

Awesome! it worked!
Anyway i had to give pemissions to node.js server when i run the project..
Now that i think about it, the first time i tried to run it before installing node.js, then i installed it and tried again.
I don't know if it is connected since you said node.js is not needed..but windows asking me to give permissions to it makes me a bit perplexed..

Anyway, thank you for your advice and for the hard work on this tool!

Thank you for the reply!

I double checked my Windows 10 installation is x64 :)

I found a jsreport.exe file in the temp folder located at

C:\Users\myuser\AppData\Local\Temp\jsreport\dotnet\binary-default-2.4.0.0

i'm not sure if it is the correct one.. i tried to run the exe, but i got the same error.. and then i noticed that the file size is 0!

Hello,

i'm looking for a suitable solution to generate some custom reports in a standalone desktop .NET application and jsreports seems a very nice one!

I've installed NodeJS (12.3.1) and i tried to create a sample project following this tutorial.

I think i'm missing something here, i installed the NuGet packages jsreport.Binary and jsreport.Local and i implemented the first example:

using System.IO;
using System.Threading.Tasks;

namespace ReportsTest
{
    public class Program
    {
        static async Task Main(string[] args)
        {
            var rs = new LocalReporting()
                                    .UseBinary(JsReportBinary.GetBinary())
                                    .AsUtility()
                                    .Create();


            var report = await rs.RenderAsync(new RenderRequest
            {
                Template = new Template()
                {
                    Recipe = Recipe.PhantomPdf,
                    Engine = Engine.None,
                    Content = "<style>h1 { color:red }</style><h1> Hello World! </h1>"
                }
            });

            using (var fs = File.Create("out.pdf"))
            {
                report.Content.CopyTo(fs);
            }
        }
    }
}

The project is a .NET Core 2.1 Console application.

When i try to run it i get the error "The specified executable is not a valid application for this OS platform"
NodeJs is in my Path and the exception doesn't specify which binary is it talking about, i can guess it is the jsreport executable in jsreport.Binary though..

The full exception:

System.ComponentModel.Win32Exception
  HResult=0x80004005

I tried to change the recipe to use ChromePDF but the result is the same..

I get this error if i run the project for "Any CPU" and "x64". I don't get any error if i run it for "x86", but no output file is generated..

Can anyone help me on this issue?

Thanks
