We are pleased to announce Day 0 support for the latest version of the .NET for TX Text Control .NET Server. At the [.NET Conf 2023](https://www.dotnetconf.net/), Microsoft officially announced .NET 8. This new version is supported for 3 years with free support and patches and is the LTS successor to .NET 6.
All update notes and especially the performance improvements can be found in a very detailed blog post by Stephen Toub.
[Performance Improvements in .NET 8](https://devblogs.microsoft.com/dotnet/performance-improvements-in-net-8/)
TX Text Control .NET Server 32.0 supports .NET 8 applications and we have tested our libraries with early versions and the final release version.
### Memory and Performance Improvements
To see how the memory footprint and performance improved, we created a simple *ASP.NET Core Web App* to test the new version.
### Creating the Application
Make sure that you downloaded the latest version of Visual Studio 2022 that comes with the [.NET 8 SDK](https://dotnet.microsoft.com/en-us/download/dotnet/8.0). Or download the .NET 8 SDK here:
[Download .NET 8.0](https://dotnet.microsoft.com/en-us/download/dotnet/8.0)
1. In Visual Studio 2022, create a new project by choosing *Create a new project*.
2. Select *ASP.NET Core Web App (Model-View-Controller)* as the project template and confirm with *Next*.
3. Choose a name for your project and confirm with *Next*.
4. In the next dialog, choose *.NET 8 (Long-term support)* as the *Framework* and confirm with *Create*.
#### Adding the NuGet Package
5. In the *Solution Explorer*, select your created project and choose *Manage NuGet Packages...* from the *Project* main menu.
Select *Text Control Offline Packages* from the *Package source* drop-down.
Install the latest versions of the following packages:
- **TXTextControl.TextControl.ASP.SDK**
- **TXTextControl.Web**
#### Configure the Application
6. Open the *Program.cs* file located in the project's root folder.
At the very top of the file, insert the following code:
```
using TXTextControl.Web;
```
Add the following code after the entry `app.UseStaticFiles();`:
```
// enable Web Sockets
app.UseWebSockets();
// attach the Text Control WebSocketHandler middleware
app.UseTXWebSocketMiddleware();
```
#### Adding the Control to the View
7. Find the *Index.cshtml* file in the *Views -> Home* folder. Replace the complete content with the following code to add the document editor to the view:
```
@using TXTextControl.Web.MVC
@Html.TXTextControl().TextControl().Render()
@section Scripts {
}
```
This code adds the Document Editor and a button to the view that loads a document generated in a server-side controller method.
8. Find the *HomeController.cs* file in the *Controllers* folder. Insert the following method to the file:
```
[HttpGet]
[Route("Home/LoadDocument")]
public IActionResult LoadDocument()
{
byte[] document;
using (var tx = new TXTextControl.ServerTextControl())
{
tx.Create();
tx.Load("App_Data/invoice.tx", TXTextControl.StreamType.InternalUnicodeFormat);
var jsonData = System.IO.File.ReadAllText("App_Data/data.json");
using (var mailMerge = new MailMerge { TextComponent = tx })
{
mailMerge.MergeJsonData(jsonData, true);
}
tx.Save(out document, TXTextControl.BinaryStreamType.InternalUnicodeFormat);
}
return new JsonResult(document);
}
```
9. Create a folder named *App\_Data* in the root of your project. Copy the files contained in [this ZIP](https://s1-www.textcontrol.com/assets/dist/blog/2023/11/16/a/assets/files.zip) file into this folder.
#### Executing the Application
When the button is clicked, the MailMerge class is used to merge the JSON data into a template, which is then returned to the editor. The Visual Studio *Diagnostic Tools* are used to monitor memory usage and document merge time. These values will be compared to the same application that is running with .NET 6.
Start the application by pressing *F5* and click the *Generate Document* button. The document is loaded and the merge process is started. The following screenshots shows the memory usage and the merge time:
#### .NET 8
In .NET 8, the maximum amount of memory that the application will use is 285 MB or process memory. The *ServerGarbageCollection* option is set to true for this demo. More information on the differences is available here: [Workstation and server garbage collection](https://learn.microsoft.com/en-us/dotnet/standard/garbage-collection/workstation-server-gc).
The time it takes to load the template, merge the JSON data, and export the document, resulting in a 25-page document, is approximately 1.9 seconds.
#### .NET 6
The same application running with .NET 6 uses 451 MB of process memory. The average time to create the document using the same template and data is approximately 2.4 seconds.
#### Conclusion
NET 8 uses approximately 35% less process memory than .NET 6 for this particular benchmark application. The time it takes to generate the document in the controller method is reduced by about 18%.
