FxCop rule extensions and related code. A project named for that well known police constable of yesteryear.

Never mind the fluff -- How do I use this?

Here's the recipe I use.

Badges

Build process from trunk as per appveyor.yml

Assumes VS2019 build environment

• dotnet tool restore
• dotnet fake run .\Build\setup.fsx
• dotnet fake run .\Build\build.fsx

The build stage can be done in Visual Studio with the Debug configuration to run the unit tests

Direction

As usual, the focus is on F#, since we don't have Roslyn analyzers there. This will include making rule variants that are more F# aware, to separate out the compiler generated clutter from the code the developer can affect -- avoiding smothering the code in [<SuppressMessage>], or throwing rules out for poor signal to noise. But there will inevitably be some originals.

Features

• JustifySuppressionRule (Dixon.Design#DX0001), the "Hello, World!" of FxCop rules. A port of the well travelled example rule to ensure that SuppressMessage attributes include a justification. See e.g. http://www.binarycoder.net/fxcop/html/ex_specifysuppressmessagejustification.html
• ReraiseCorrectlyRule (Dixon.Design#DX0002) : only throw and exception you've just created
