Question: Couldn't add FastReport .NET components on Form in Visual Studio


You should add FastReport.Editor.dll, FastReport.VSDesign.dll, FastReport.Web and FastReport.dll to the GAC. For it open Visual studio tools folder(C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\Tools\Shortcuts), open Developer Command Prompt for..., and write gacutil -i "reference path+ name.dll"(gacutil -i "Program Files\FastReports\FastReport.Net\Framework 2.0\FastReport.dll").Read more about GAC there -

After this add FastReport controls in Visual Studio Toolbox: right click on Toolbox -> Choose Items -> Choose FastReport.dll from GAC and press OK.
