LinqContraband.Scan 5.11.0

LinqContraband.Scan

Scan any .NET solution for EF Core LINQ problems without adding a package to it.

dnx LinqContraband.Scan                 # .NET 10 SDK, no install step
dnx LinqContraband.Scan -- MyApp.sln -o results.sarif

dotnet tool install -g LinqContraband.Scan   # .NET 8 or 9 SDK
linqcontraband-scan MyApp.sln

The scanner builds your solution with the LinqContraband analyzers injected, then prints the rules that fired, how often, the most affected files and a link to each rule's page. It also writes a SARIF 2.1.0 file you can upload to GitHub code scanning. Your project files are not changed.

Output looks like this:

LinqContraband found 14 problems (5 rules, 6 files).

  Rule   Severity Count  Title
  LC007  Warning      6  N+1 Problem: Database execution inside loop
  LC009  Info         4  Performance: Missing AsNoTracking() in Read-Only path
  ...

To keep the checks on in the editor and in CI, add the analyzer package: dotnet add package LinqContraband.
