dotnet core projects skipped by SonarQube: missing ProjectGuid in .csproj

Not specified by the original author.

TL;DR: The default dotnet core project template does not include a ProjectGuid tag, so SonarQube skips those projects. Context: Stack Overflow #50479716 (accepted answer, 37 votes): dotnet core projects get skipped from SonarQube analysis with the warning "The following projects do not have a valid ProjectGuid and were not built using a valid solution (.sln) thus will be skipped from analysis".

dotnet core projects skipped by SonarQube: missing ProjectGuid in .csproj

Fix

1. The default dotnet core project template does not include a ProjectGuid tag, so SonarQube skips those projects. Expected: this specific failure stops.

2. Fix it in each .csproj by adding a ProjectGuid element containing a fresh GUID, nested inside a PropertyGroup element of the file. Expected: this specific failure stops.

3. Dont copy one GUID across projects; duplicates make the analysis treat them as the same project. Expected: this specific failure stops.

4. Rebuild, re-run the scanner, and the "no valid ProjectGuid" warning goes away. Expected: this specific failure stops.

[accepted answer]: default dotnet core .csproj templates ship without a ProjectGuid element, and SonarQube requires one. Generate a new GUID per project (Visual Studio has Tools > Create GUID, PowerShell has New-Guid, mac and linux have uuidgen).
