Asked On July 11, 2017 04:16 PM UTC

I am trying to install the required Nuget packages for DocIo in Asp .NET Core.
There are two sets available:
Syncfusion.DocIO.AspNet.Core and

Installing the Core version fails. The set of Portable packages succeed, but than I can't use a System.Data.DataTable to seed Mail Merge.
wordDocument.MailMerge.ExecuteGroup( dataTable);

Any clue why the AspNet.Core are not loading?

I am using VS2017 and AspNet.Core 1.1

Hi Pieter,

Thank you for contacting Syncfusion support.

I can't use a System.Data.DataTable to seed Mail Merge:
Currently Essential DocIO doesn’t support the functionality to perform Mail merge with System.Data.DataTable in ASP.NET Core due to unavailable functions in it.

Alternatively you can use the
MailMergeDataSet and MailMergeDataTable to perform Mail merge in ASP.NET Core. Please refer the below online sample link, and let us know if this helps you.

Hi Pieter,

Thank you for your update.

On further analysing with the given details, we found that you have used an unsupported older packages (Syncfusion.DocIO.AspNet.Core) of ASP.NET Core in net461 framework which causes the issue. So, kindly use the latest packages (Syncfusion.DocIO.Portable) of ASP.NET Core which will supports the mentioned framework.

Please let us know if you have any other questions.
