Good day,
Do you have a version of Essential Studio assembly for ASP.NET Core Web Application (using .NET Framework) not only for .Net Core?

Dear Karthick,

I tried referencing the syncfusion asp.net mvc packages for an ASP.NET Core project targeting net461 and I get the following error:

Error  NU1002 The dependency Syncfusion.EJ.MVC 14.2600.0.28-preview2-final does not support framework .NETFramework,Version=v4.6.1.

The error is eliminated though when the target framework is netcoreapp1.0

Dear Isuriya ,

Thanks for the info!
The issue you are mentioning though is when the target framework is netcore.
Also, the sample project you prepared is also targeting netcore.
I was able to use the library with the attached setup.

I am unable though to use it if I target net461 or net452 and in general when targeting the .NET Framework.

Hi Karthick.

+10 for solution.

Your assemblies target only pure .net core solutions.
You should build (target) assemblies not only for .net core but at least for .net 451 too.
This is not practical if you use it (for example) as Windows service.


Just create simple ASP.NET Core WebApi Controller and use WordDocument class in it.
For example create mailmerge and return result to client.
We just need to reference Syncfusion .DocIO.MVC from nuget and include Syncfusion.DocID.DLS.

After build everything is perfect. 
We can run application and mailmerge is working.

But what if we want to use that apllication as Windows service ?
From ASP.NET Core point of view it's simple.
We can use Microsoft.AspNetCore.Hosting.WindowsServices
target framework to net451 (because windows services works only on windows) and build project.

If we don't use Syncfusion restore & build will succeed, with Syncfusion Will not.
Because you are not targeting .NET 4.5.1.

So please let us know if this is possible and when targeting .NET framework Will be supported.

Thanks for advance.

Hi Edvin, 
Sorry for the inconvenience. 
We have considered your requirement (“You should build (target) assemblies not only for .net core but at least for .net 451 too.”) and added it to our feature request list. We will provide the asp.net core support for specific .NET Framework version (.net451) in our next main release (Volume 4, 2016). Please use the latest version (“netcoreapp1.0”) until we provide the support. 
Please let us know if you have concerns.

I tried downloading latest version (14.4600.0.20-preview2-final) from Syncfusion nuget  source but I still had the same error.

Do you know when the update will be available?

HI Alberto, 
Sorry for the inconvenience. 
Due to internal complexity, we haven’t included the mentioned feature (asp.net core support for specific .NET Framework version) in Volume 4, 2016. 
We will include this feature in our upcoming Main Release Volume 1, 2017 which is expected to be available on mid of February 2017. We appreciate your patience until then.

Same issue here: ASP.NET Core project targeting net461. 

Using File Formats Syncfusion.XlsIO.Portable package. Getting this error on my Azure Kudu deployment:

"Unable to resolve 'Syncfusion.XlsIO.Portable (>= 15.1120.0.33)' for '.NETFramework,Version=v4.6.1'": "15.1120.0.33"

Any update as to when we can expect assemblies targeting 461?

Hi Darren, 
We are not able to reproduce the issue in Azure website on targeting net461.  
Could you please share us the details about dependencies used in your application and confirm us whether you are facing the issue other than Kudu tools?
