Because I have no programming skills a developer developed a website for me in VS2010. To become independent, I recently switched over to the latest (16.8.4) VS2019 Community. Now I want to remove version VS2010, but when I do so, version VS2019 reports build error problems. A Dutch forum poster assisted me to modify the .sln and .csproj files to run with VS2019 without VS2010. Unfortunately, we both seem to miss something to get the project to build with VS2019.
This is my present situation:
I notice missing references in .csproj VS2019 with respect to the VS2010 version. Just pasting (as to be expected) all the references from .csproj version VS2010 to VS2019 does not solve the problem. Can this be caused by wrong access paths or is there a different cause? (Maybe there are other links, but I don’t need all the stuff like Github, TourtoiseSVN and VisualSVN which are implemented in VS2010 at present)
I tried building a new .csproj fle but that appeared too difficult for me and so I now am running out of options. I followed these suggestions: How can I recover a corrupt .csproj file in Visual Studio 2010? and How to generate .csproj file in visual studio 2019? and did a lot of Googling and went through the posts regarding related .csproj questions. Actually I spent days on finding a solution. I also started an on-line training course at Udemy.com (Basic C#)
I would appreciate it if some is willing to go through my .csproj file to find the cause of my problem.

This is the proj which I have tested in my VS2019 without any errors. If it did not work, you should share a sample of your project by a shared onedrive or a public github repository with us. Mostly the issue might have a conflict between your project files and proj file.
