HI.
I am trying to load a legacy LightSwitch project (*.lsproj), but it looks like a package to interpret the project no longer exists. I have installed the Visual Studio Toolkit for 2015 and still does not recognise the project. I have attached both error screens when I open the main solution project.
Can anyone help on this?
Thanks.
John.

You may try to reinstall the LightSwitch, or try to install Microsoft Developer Tools for Visual Studio 2015(not sure if it’s still available).
Looks like the same issue was reported before: LightSwitch Designer Hosting package did not load correctly.

2023-12-06T12:52:02.7933333+00:00 Apologies. I did know that. I am looking for any way to open the project in Visual Studio 2015. Someone out there must have had to do this I'm guessing/hoping?
