ASP.NET Core Web Applications

TX Text Control .NET Server for ASP.NET can be used in ASP.NET Core Web Applications to create, edit and merge documents. This tutorial shows how to prepare a Visual Studio project to use the TXTextControl.ServerTextControl Class and the TXTextControl.DocumentServer.MailMerge Class.

This tutorial shows how to prepare an ASP.NET Core Web Application to use with TX Text Control.

Create Your Application

  1. In Visual Studio 2019 (> 16.5.4), create a new project and select ASP.NET Core Web Application as the project template.


  2. Select a project name (myDotnetCoreApp in this sample), location and solution name in the next dialog and confirm with Create.


  3. In the last dialog, select .NET Core and ASP.NET Core 3.1 as the project target, select Web Application (Model-View-Controller) as the template and confirm with Create.


  4. Open the Package Manager Console by choosing Package Manager Console from the Tools -> NuGet Package Manager main menu and type in the following command to install the System.Drawing.Common package:

    PM> Install-Package System.Drawing.Common

  5. While the project is selected in the Solution Explorer, choose Project -> Add Reference... to open the Reference Manager. In the opened dialog, select Browse... to select the required TX Text Control assemblies. Navigate to the installation folder of TX Text Control and select the following assemblies from the Assembly folder:

    • TXDocumentServer.dll
    • TXTextControl.dll
    • TXTextControl.Server.dll
    • TXDrawing.dll


    Repeat this step with the following assemblies from the Assembly/bin64 folder:

    • txic.dll
    • txkernel.dll
    • txtools.dll
    • txpdf.dll

    After selecting these assemblies, close the Reference Manager by confirming with OK.

  6. While the project is selected in the Solution Explorer, choose Project -> Add Existing Item.... Browse to the TX Text Control installation folder and select the following files from the Assembly/bin64:

    • tx30_xml.dll
    • tx30_css.dll
    • tx30_doc.dll
    • tx30_dox.dll
    • tx30_htm.dll
    • tx30_pdf.dll
    • tx30_rtf.dll
    • tx30_xlx.dll
  7. Select the files from step 6 in the Solution Explorer and set the Copy to Output Directory to Copy always.

  8. While the project is selected in the Solution Explorer, choose Project -> Add New Item.... Select Text File, name the file licenses.licx and close the dialog by clicking Add.


    Open the newly added file and add the following content:

    TXTextControl.ServerTextControl, TXTextControl.Server, Version=30.0.1500.500, Culture=neutral, PublicKeyToken=6b83fe9a75cfb638

    Set the Build Action property to Embedded Resource.

    In case, you are getting compile errors (MSB6003 The specified task executable "lc.exe" could not be run.), please refer to this article:

Now, you can use ServerTextControl and MailMerge in your .NET Core 3.1 Web Application:

public IActionResult Index()
    using (TXTextControl.ServerTextControl tx = new TXTextControl.ServerTextControl())
        // ...

    return View();
