Hi Gert.C
If you don't deploy your LightSwitch successfully on your side, you could follow this guide to
deploy a Three-Tier LightSwitch application.
> - Strong name signature not valid for this assembly vslshost.exe.
For this
vslshost.exe issue, our community members gives detailed explanation before.
You publish your LS App somewhere (even on your development machine) & run the setup program found in the folder that you publish to
Once the application is published, there'll be an icon in the Start Menu to run the application from. You can run the published application by clicking on the icon.
You can, but shouldn't, actually run the published application from the setup.exe file, but defintely not "vslchost.exe".
hope it helps.
