NET-3376 Fix S6930 AD0001: Issue on template / code files for blazor #9789
Description
Description
Running the analyzers on a generated razor / razor.cs file combo in a blazor project get's me this:
12:47:07.867 4:7>CSC : warning AD0001: Analyzer 'SonarAnalyzer.CSharp.Rules.BackslashShouldBeAvoidedInAspNetRoutes' threw an exception of type 'System.ArgumentException' with message 'Syntax node is not within syntax tree'. [/home/vsts/work/1/s/src/Project/Project.csproj]

When combining the files (by using @ code inside the razor file) I don't get this issue anymore... I also tried marking the generated files as generated in the editorconfig and settings the analyzer S6930 to None in it for those files, but that didn't work either.
Scanner: SonarScanner for .NET via Azure DevOps SonarCloudPrepare@3 / SonarCloudAnalyze@3
Analyzer: SonarAnalyzer.CSharp (rule S6930), exact package version not pinned in repo because SonarCloud injects it.
