Since converting a DSL-tools language to Visual Studio 2015, the toolbox options are gone, there are no options to add model elements to the DSL editor.

If I select the "Show All" option in the Visual Studio 2015 toolbox I see a strange "Cannot load resource" entry that I'm assuming that corresponds to the toolbox tab of my DSL.

Visual Studio Toolbox

Does anyone have any idea of what is happening here or any tips on how to diagnose how Visual Studio 2015 loads the toolbox so that I can find which is the "resource" that it cannot load?

Finally I found the solution a little by chance. This post pointed me in the right direction:

DSL designers built from migrated beta 2 solutions might have empty toolbox

The setting missing in the DSL package csproj file was the following:

<RegisterWithCodebase>true</RegisterWithCodebase>

It got lost in the transition from Visual Studio 2013 to Visual Studio 2015 while editing the projects references.
