Fsharp: error FS2026: Deterministic builds only support portable PDBs

[jmecosta]

well bummer, updated visual studio to 16.2.1 and now FSharp no longer compiles.

i hope im not the only one having this issue. those are caused by

<PropertyGroup Label="Configuration" Condition=" '$(Configuration)' == 'Debug' ">
  <DebugType>full</DebugType>
  <Optimize>false</Optimize>
  <UseDebugLibraries>true</UseDebugLibraries>
</PropertyGroup>

<PropertyGroup Label="Configuration" Condition=" '$(Configuration)' == 'Release' ">
  <DebugType>pdbonly</DebugType>
  <Optimize>true</Optimize>
</PropertyGroup>

that we centrally managed since like forever. How can i fix this now? thanks

by the way im targetting net472, so the debugtype full should work on this conditions

@jmecosta the coreclr has only ever supported portable pdbs with deterministic build.

We recently … 4 months ago, added support for deterministic to the F# compiler.

Unfortunately, the dotnet SDK property for deterministic "Deterministic" defaults to true, we would rather not have a different property for F# only, and that means that projects that use the netsdk and set the debugtype to Full will need to add this near where the debugtype is set to full, or use portable pdbs.

<Deterministic>false</Deterministic>
It should be noted that only the desktop F# compiler supports generating full pdbs and so I recommend switching to portable pdbs, or even better embedded pdbs.

@KevinRansom Is this considered by design then?

[KevinRansom]

Yes, it is.

[jmecosta]

@KevinRansom yes ive found the solution for this

<DebugType>portable</DebugType>

however doesnt seem to work always
