This window contains several sections. 

1. Framework Version 

The Framework Version group box has six options: .NET 2.0, .NET 3.5, .NET 4.0, .NET 4.5, .NET 4.5.1, .NET 4.6, .NET CORE 3.1 and NET 5.0.

  • When .NET 5.0 is installed in your system, the NET 5.0 option is selected by default.

  • When .NET CORE 3.1 is installed in your system, the .NET CORE 3.1 option is selected by default.

  • When Visual Studio 2017 is not installed in your system, the .NET 4.6 option is selected by default.

  • When Visual Studio 2015 is not installed in your system, the .NET 4.5.1 option is selected by default.

  • When Visual Studio 2013 is not installed in your system, the .NET 4.5 option is selected by default.

  • When Visual Studio 2012 is not installed in your system, the .NET 4.0 option is selected by default.

  • When Visual Studio 2010 is not installed in your system, .NET 3.5 option is selected by default. 

  • When Visual Studio 2008 is not installed in your system, .NET 2.0 option is selected by default. 

You can change the default option by clicking the other button. The version of the .NET Framework that the assemblies should be built with is specified here and is used automatically to rebuild the assemblies. 

2. Product

The Product group box has a drop-down list box. By default, All is selected. You can change the default option by selecting one of the products from the drop-down list box. 

3. Platform Type

Syncfusion products typically share a base library that serves as the foundation for both the Windows and Web variants. The Platform Type specifies the library category to be built. This frame comes with eight different options. By default, everything is selected. To perform the build operation, click the button for the required product.


For assemblies that are not built and pre-compiled, assemblies that shipped with the product is automatically used.

4. Assembly Type

This frame has two options: Debug and Release. Debug is selected by default. To choose the Release mode for assembly, select Release.

You can switch between the Debug and Release mode of product configurations. Building the Debug version of the assemblies allows you to step into the Syncfusion assemblies when debugging applications. 

5. Strong Key

This enables you to install the compiled assemblies in GAC. Select the Use Strong Key check box and choose a .snk file to achieve this. You can debug the assembly only when it is complied with the Strong Key.

6. Output

This frame shows the output, that is, the status of the build operation, in a text area. 

After selecting the required options in the above-mentioned frames, click Perform Build inside the output frame.


The Build operation is performed and the status is updated in the text area, inside the output frame. On completion of the Build operation, an information message is displayed stating that the Build operation has been completed. It also asks you to review the Build output and log files for additional information.
