Code migration from SharePoint 2013 to SharePoint 2019 failed in Visual studio 2019

Shahid K 11 Reputation points

I have custom C# code which was written for SharePoint 2013 using Visual Studio 2015. We now moved from SharePoint 2013 to SharePoint 2019. The custom code also needs to migrate.

When I opened that solution in Visual Studio 2019 Ent for SharePoint 2019, it asked me to upgrade/migrate.

After upgrade also, I got some missing SharePoint DLL reference errors. I fixed them by referring from ISAPI folder. However all build errors are gone but when I deploy solution on a SharePoint 2019 site I get 0 error but build fails and says 1 failed.

    You could try to restart the VS/Computer, maybe it would work for you.
