I have been coding with SAP Business One SDK since 2006. Working with Visual Studio and integrated fonction from B1 Studio is really great.

But when I have upgraded Visual Studio to 2017 version, I found out that it wasn't supported with B1 Studio (see https://launchpad.support.sap.com/#/notes/2108204 ).

But with the following tips, I could develop as smooth as before.

First step : Modify register keys

  • Open regedit,

  • navigate to HKEY_CURRENT_USER\Software\Microsoft\VisualStudio


  • Rename keys from 15.0 o 10.0

  • Install B1 Studio

  • Rename keys from 10.0 to 15.0

If you have  also  VS 2010, you'll have to change key too.

Second Step : Dealing with templates

There's two kind of template :

  • item

  • Project

In Vs2010, the paths are like :

  • C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\ItemTemplates\CSharp

  • C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\ProjectTemplates\CSharp

In Vs 2017, we have to move into the following directory

  • C:\Users\<username>\Documents\Visual Studio 2017\Templates\ItemTemplates\Visual C#

  • C:\Users\<username>\\Documents\Visual Studio 2017\Templates\ProjectTemplates\Visual C#


You'll just have to start Visual Studio to create Add-on solution and work with designer.


Work with B1 item


Add item template


I guess this solution should be working with 2019 version of Visual Studio, but I haven't tried yet.


As of release 10.0 FP 2008, SAP Business One Studio Suite supports Microsoft Visual Studio 2017 and 2019 (https://launchpad.support.sap.com/#/notes/2936980)
