r/dotnet on Reddit: Can the command dotnet format cause runtime errors?
January 12, 2023 -

We have a pretty large code base at our work.

I understand that there might be warnings that could be triggered by using "dotnet format" that could lead to build errors. But is it possible that it changes the logic of the code?

If I run it on a large code base, should a tester test it again thereafter?

The chances that something goes wrong is pretty small, but it's unsurprising that you've been met by concern, especially without a lot of automated testing in place. One suggestion that I have is to set up Husky.Net . It'll allow you to ensure that dotnet format is run on every staged file. Assuming you guys are doing appropriately sized commits and PRs, your team will be able to evaluate formatting changes better by reviewing them in chunks as they come in, and not all at once in a large codebase. It's pretty easy to get set up if you read their docs, and once that's done, other team members will just have to run dotnet tool restore && dotnet husky install once per machine/workstation. I can't remember where they have docs on setting up integration with dotnet format, but essentially you create task-runner.json in .husky/, which looks like: { "version": 1, "isRoot": true, "tools": { "husky": { "version": "0.5.4", "commands": [ "husky" ] } } } and then your pre-commit hook will run dotnet husky run -v --group "pre-commit" edit: found link to their example https://github.com/alirezanet/Husky.Net/discussions/41

Answer was provided in this link.

@ViktorHofer the root cause here is that this repo didn't flow dependencies correctly. That meant it missed a version bump for the Roslyn compiler. As such it was referencing Microsoft.CodeAnalysis at version 4.4.0. That means on startup dotnet format was effectively pulling in Microsoft.CodeAnalysis at 4.4.0 into the primary AssemblyLoadContext. Many analyzers in the SDK had moved to reference 4.5.0 though and when such an analyzer was loaded into dotnet format the compiler saw the version mismatch and rejected the analyzer.

The reason this doesn't always happen is different analyzers come into play for different project types. This bug does not reproduce on a console app but will reproduce on pretty much every razor app. The reason being that they bring in different sets of analyzers.

The problem will likely be fixed in a coming update expected to drop in CW25.

I've noticed this same issue in GitHub Actions, but wasn't able to reproduce locally.

It seems, according to this GitHub issue, that it's related to having the version 6.0.200 of the SDK installed on your machine. The suggestions in that thread are to either rename 6.0.200 or uninstall it entirely, but I haven't found another workaround.

You need to check your version of dotnet format. I the new version - v5.1.22507 the feature of format run on solution filter using - dotnet format solution.slnf.

This will not work prior to the above version.
