VS Binlog has evaluations that don't include property/item data with MSBUILDLOGIMPORTS about msbuild HOT 6 OPEN

Have been able to reproduce the issue:

1. Create a vcxproj console project from a VS template
2. Open a cmd and set MSBUILDLOGIMPORTS and MSBUILDDEBUGENGINE environment variables.
3. Open the solution from the same cmd: <path to devenv.exe> <solution_name>
4. Run build
5. Check MSBuild_Logs folder for binlogs with missing items and properties.

from msbuild.

The ProjectInstance (or Project) can be created and evaluated standalone. They can then be used to issue build requests.
That's how those 2 events get executed separately.

I'll double/triple check and debug the scenario next week (away from my devbox now) to confirm the theory.

Have we validated that @JanKrivanek's change actually fixes this?

Binlogs obtained from VS have always been deficient and missing info. The Project System Tools extension was especially bad, but even the MSBUILDDEBUGENGINE=1 mode produces no evaluation and I thought it's because CPS evaluates separately from builds.

See related:

• dotnet/project-system-tools#256
• dotnet/project-system-tools#257

I don't think MuxLogger is the problem. I have an environment where MuxLogger is present but still the binlogs have the full information.

from msbuild.

Another way to test this is set the env variable MSBUILDLOGPROPERTIESANDITEMSAFTEREVALUATION=1 and see if it fixes things. If it does then yes, it indicates a legacy logger is present.

But I suspect it won't fix it.

there will be no evaluation in the logs of build, because it already happened, but there should be a log with evaluations in it, and this one seems to be that one . . . except they're incomplete.

I've never understood how are evaluations separate from build? How is it implemented?
