Visual studio professional 2022 MSBuild gives less warnings then Visual studio build tools 2022

[MatthijsPrent]

Repro steps

Provide the steps required to reproduce the problem:

1. Build the solution via the cmd using the MSBuild.exe that was provided with VS pro 2022.
2. Build the solution via de cmd using the MSBuild.exe that was provided with VS build tools 2022.

Expected behavior

I would expect the result to be equal, and the warning messages to be the same.

Actual behavior

With the build tools version of VS build tools 2022, more warnings are shown then with the VS pro 2022. For example FS3570 is shown using the Build tools, but not using visual studio in the following code:

Known workarounds

None

Build tools seem to be newer, we need to check when we introduced this warning by default as well as make sure it behaves as expected on the same version of VS and build tools.

The information warning was added in F# 6.0, which was first delivered in VS2022.0 so both compilers should definitely produce the same output.

Indeed I do see the same output from one that I built, on both build tools preview 1.1 and VS Enterprise 17.2.3.
Is it possible that on one of the builds you forgot to add a /t:rebuild to ensure that it actually rebuilds the project.

please note that this is the Build Tools install, you can tell because it still points to the 32 bit version of program files.

If you are still seeing this we can dig in further, please build with the /bl option for each vs install and attach the msbuild.binlog file, and we can investigate further.

I hope this helps

Thanks for reporting this
I checked with the buildtools now up on visualstudio.com, it produces the correct diagnostic output.

closing this issue.
