2 years ago I'm sorry that you're having trouble. PdfMerge is definitely a work in progress, but I am able to build and run it on my system.
The warning errors that you're getting are strange, such as: "Warning The referenced component 'System' could not be found. PDFmerge" "Warning The referenced component 'Microsoft.CSharp' could not be found. PDFmerge"
That's really strange that VS can't find "System" or "Microsoft.CSharp". Have you tried restarting Visual Studio?
Another possible solution is to comment out a few lines in the Project File: PDFmerge.csproj. Open that file in a text editor and comment out lines 164-171, as shown in the screenshot below. Then reload the project and try building and running it agian.
You can try changing the target framework from .NET 4.6 to .NET 4.8, but it might throw some errors. You might have to update the NuGet Packages to work with .NET 4.8, if they even support .NET 4.8.
The only NuGet packages that you should need are: Microsoft.Web.WebView2 and PDFsharp. I'm using WebView2 version 1.0.1245.22 and PDFsharp version 1.50.5147.
I'm using VS 2019 currently. I haven't upgraded to VS 2022, so I'm not sure if that changes anything.
Best of luck. Let me know if you have any other questions.
Hi @hambone-the-Great,
Quick questions and answers (hopefully).
1. I'm using Visual Studio 2022 and received the following 18 warnings after cloning your project locally on my laptop.
ERROR LIST: Severity Code Description Project File Line Suppression State Warning The referenced component 'Microsoft.CSharp' could not be found. PDFmerge Warning The referenced component 'Microsoft.VisualBasic' could not be found. PDFmerge Warning The referenced component 'Microsoft.Web.WebView2.Core' could not be found.

PDFmerge C:...\source\PDFmerge\PDFmerge.csproj 168
2. Installing Net Framework 4.6 is not possible because the installer stated my system has the most current version and I prefer not to uninstall it in order to rollback to 4.6.
3. Any attempt to update the References via NuGet Package Manager, e.g. Microsoft.CSharp resulted in the following error messages in the Output and Error List panes:
OUTPUT PANE: Attempting to gather dependency information for package 'Microsoft.CSharp.4.7.0' with respect to project 'PDFmerge', targeting '.NETFramework,Version=v4.8' Gathering dependency information took 146 ms Attempting to resolve dependencies for package 'Microsoft.CSharp.4.7.0' with DependencyBehavior 'Lowest' Resolving dependency information took 0 ms Resolving actions to install package 'Microsoft.CSharp.4.7.0' Resolved actions to install package 'Microsoft.CSharp.4.7.0' Adding package 'Microsoft.CSharp.4.7.0' to folder 'C:...\source\packages' Added package 'Microsoft.CSharp.4.7.0' to folder 'C:...\source\packages' Added package 'Microsoft.CSharp.4.7.0' to 'packages.config' Successfully installed 'Microsoft.CSharp 4.7.0' to PDFmerge Executing nuget actions took 1.25 sec Time Elapsed: 00:00:02.4090461 ========== Finished ==========

4. Clicking the "Restore" button in the NuGet ribbon does nothing, the list of References with Exclamation symbols does not change.
5. Selecting a previous version, eg. 4.0.0 resulted in the following detailed error message in the Output Pane:
