Download assets first

Assets like bitmaps, fonts, or PDF files are not part of the repository anymore. You must download them before compiling the solution for the first time. Use download-assets.ps1 in the dev folder to create assets folder required for some unit tests and needed by some projects.

Execute

.\dev\download-assets.ps1

Build the solution

dotnet build should build the solution without any warnings or errors.

You need the latest .NET SDK version installed
Please note that you need a git repository with at least one commit in order to build the PDFsharp solution.
Without a git repository with at least one commit, you will get an error message from GitVersion.MsBuild while building the solution. You can set a tag to define a valid version, e.g.: git tag v6.2.0 to make it build with a specific version number. Without tag, version 0.1.0 will be used.

Central package management

The solution uses central package management. Version numbers for all referenced packages are stored in file Directory.Packages.props in the src folder. When adding new packages, add the required version here.
