Please share your code... how you register extensions and how your rendering request looks like.

Could you try to describe more in details how would you like this to work?

I would guess that it will (from one part) work the same way as the xlsx recipe.
There will be a new entity "docx template" which will represent the binary docx file uploaded by user.
This entity will be associated with the normal template. Just like the xlsx template.
The new recipe will somehow run a tool of your choice and fill the associated template.
So I believe very similar what xlsx recipe does.
The difference would be that there will be a tool used to fill the docx.
Where in xlsx we unzip the xlsx, fill it using templating engines and zip it back.

Here you can find xlsx sources

I've never seen this error...

You can zip the data folder and email it to me. I would take a look.
I would additionally need the exact jsreport version you use and when this error occurs.

Would you consider updating jsreport to the latest version?
Storing templates is completely reworked there.

Hm, could you try it on a different pc?
Can you try to turn off an antivirus temporarily?

I don't see a reason why that console example application should run once and not the second time.

Btw the .net applications are using the same licensing principle.
You can use it for free only if you store <= 5 templates.
There is no exception here.
https://jsreport.net/learn/faq#5-templates-limitation-in-free-plan

If you don't store templates in jsreport and send it inside the request like when using asp.net mvc razor, you can use it for free.
But you can do the same if you run full standalone jsreport. It is not related just to the jsreport.Local .net nuget package.

Hm no. Are you able to replicate it in playground?
Do you see the same behavior with "hello world" template or this is just happening for your particular template?

Hi,

nice! Glad to see jsreport in such use case.

Structuring entities into directories is the most requested feature and we are just working on it.
I believe we are done very soon. I hope max one month.

Until then you can use jsreport tags to label the templates and then switch the jsreport studio tree display to structure entities using tags.

Hi,

Realibility of the platform because when I run in local sometimes it runs, sometimes not. Is this problem a common occurrence?

Rendering performance: With the samples sometimes the invoice report give me a timeout exception and is a fairly simple report. The orders report always give me a timeout exception. The performance depends of the machine power? Are there other things that I have to take in consideration (my pc is not the greatest).

The same happens on your official examples? Like this one https://github.com/jsreport/jsreport-dotnet-example-consoleapp
You are trying it on your local computer? It should work just fine then.

Deployment: Maybe this is offtopic, I don't have experience deploying c# apps, I have to run a console project that will run the webserver with jsreport studio? How I change the configuration so it use the production enviorement. I'm not asking for concrete solutions but a head start will be appreciated.

Yes it can work this way. You can pass the production/development configuration right from c#. You can load these from an app.config if you like.
However, do you plan to run just jsreport web server? Do you actually need to run it through .net? You could run full jsreport on prem server directly.

Framework: I don't know if is just my thoughs but the webserver solution works better with .net core. I know that the libraries use .net standard so it shouldn't be a problem using it with full .net.

I am currently not aware that jsreport.Local would run better with .net core or full framework. I think it should run the same in the both cases.

Thank you for sharing the json. It helped me to track the problem. It sits in the jsreport core deserializer.

Please use workaround that manually serializes the data field in .net

var manuallySerializedData = JsonConvert.SerializeObject(new
{
  a = new int[3] { 1, 2, 3 }
});
var report = rs.RenderByNameAsync("a", manuallySerializedData).Result;

We will make sure to fix this in jsreport during the next release.

The jsreport.client uses json.net feature to preserve references.
https://www.newtonsoft.com/json/help/html/PreserveReferencesHandlingObject.htm
https://github.com/jsreport/jsreport-dotnet-shared/blob/master/jsreport.Shared/SerializerHelper.cs#L113

It seems that it somehow creates invalid format of such json in the end.
Would you be able to send me the data you are passing into the rendering request?
