CUSTOMTOOLS API could be used to develop customized script add-ins to CUSTOMTOOLS. To create script add-ins to CUSTOMTOOLS products you need to have Microsoft Visual Studio IDE (Integrated Development Environment) and the Microsoft .NET Framework version that is compatible with your installed CUSTOMTOOLS version. The following requirements apply to the CUSTOMTOOLS 2015 and newer versions:

• Microsoft Visual Studio 2015. Since the CUSTOMTOOLS 2019 version, the CUSTOMTOOLS products are built with the Microsoft Visual Studio 2015. For that reason the recommended version of the Microsoft Visual Studio is based on the version the CUSTOMTOOLS products are built with.

• Microsoft .NET Framework v4.5.1. Since the CUSTOMTOOLS 2017 version, the CUSTOMTOOLS products use the Microsoft .NET Framework version 4.5.1. All script add-ins you create are compiled in all cases against the Microsoft .NET Framework version 4.5.1 by the CUSTOMTOOLS Administration Tool when you apply your script to your CUSTOMTOOLS environment.

  You can develop script add-ins also against an older version of the Microsoft .NET Framework but in that case, all functions available may not be fully compatible and for that reason it is recommended to use the Microsoft .NET Framework v4.5.1 as mentioned in this documentation.

NOTE: Requirements and/or recommendations in relation to the Microsoft Visual Studio IDE may vary by the CUSTOMTOOLS products' major versions.
