Installing on a Developer Machine
When using the DevExpress .NET Installer on a development SharePoint machine, all required assemblies are automatically registered in the GAC.
Deployment to the Target Server
In order to use DevExpress ASP.NET products on the target SharePoint site, the corresponding DevExpress assemblies should be available on the target server in the GAC.
See the Redistribution and Deployment help topic to learn more about the assemblies required for each product.
The command below demonstrates how to install the DevExpress.Data assembly into the GAC using the gacutil (the “C:\Program Files (x86)\Microsoft SDKs\Windows\v8.0A\bin\NETFX 4.0 Tools\gacutil.exe” path for .NET v4) tool.
gacutil –i DevExpress.Data.v19.2.dll
