How is the references created to fsc when building a F# project? - f#

Question

We have a F#-project that fails to build on teamctiy and can't figure out the solution to it. It seems like when building through teamcity the arguments to fsc is not correct for us. If I run msbuild /t:Rebuild /p:Configuration=Release manually on the same source it all work just fine.
I'll provide the content of the failing fsproj-file to show what I mean (it's not a large project):

When running msbuild manually we get the correct arguments to fsc.exe:
C:\Program Files (x86)\Microsoft SDKs\F#\4.0\Framework\v4.0\fsc.exe -o:obj\Release\SFag.DataRepository.dll --debug:pdbonly --noframework --define:TRACE --doc:bin\Release\SFag.DataRepository.XML --optimize+ -r:E:\TeamCity\buildAgent2\work\cd80d924274f60cd\src\packages\FSharp.Core\lib\net40\FSharp.Core.dll -r:E:\TeamCity\buildAgent2\work\cd80d924274f60cd\src\packages\FSharp.Data.SqlClient\lib\net40\FSharp.Data.SqlClient.dll -r:"C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.6.1\mscorlib.dll" -r:E:\TeamCity\buildAgent2\work\cd80d924274f60cd\src\Sfag.Contracts\bin\Release\Sfag.Contracts.dll -r:"C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.6.1\System.Core.dll" -r:"C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.6.1\System.Data.dll" -r:"C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.6.1\System.dll" -r:"C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.6.1\System.Numerics.dll" -r:"C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.6.1\System.Xml.dll" --target:library --warn:3 --warnaserror:76 --fullpaths --flaterrors --subsystemversion:6.00 --highentropyva+ "C:\Users\admtoja1\AppData\Local\Temp\.NETFramework,Version=v4.6.1.AssemblyAttributes.fs" AssemblyInfo.fs Tilsynsmyndighet.fs KonsesjonRepository.fs
When teamcity runs the build we don't get the exact same output:
C:\Program Files (x86)\Microsoft SDKs\F#\4.0\Framework\v4.0\fsc.exe -o:obj\Release\SFag.DataRepository.dll --debug:pdbonly --noframework --define:TRACE --doc:bin\Release\SFag.DataRepository.XML --optimize+ -r:E:\TeamCity\buildAgent2\work\cd80d924274f60cd\src\packages\FSharp.Core\lib\net40\FSharp.Core.dll -r:"C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.6.1\mscorlib.dll" -r:E:\TeamCity\buildAgent2\work\cd80d924274f60cd\src\Sfag.Contracts\bin\Release\Sfag.Contracts.dll -r:"C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.6.1\System.Core.dll" -r:"C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.6.1\System.Data.dll" -r:"C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.6.1\System.dll" -r:"C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.6.1\System.Numerics.dll" -r:"C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.6.1\System.Xml.dll" --target:library --warn:3 --warnaserror:76 --fullpaths --flaterrors --subsystemversion:6.00 --highentropyva+ "E:\TeamCity\buildAgent2\temp\buildTmp\.NETFramework,Version=v4.6.1.AssemblyAttributes.fs" AssemblyInfo.fs Tilsynsmyndighet.fs KonsesjonRepository.fs
The error is that in the Teamcity version there is no reference to FSharp.Data.SqlClient. This is really strange since I thought teamcity would just call msbuild on my solution.

Answer 1

FSharp.Data.Client is coming from a NuGet package and I would have a guess that NuGet packages are not being restored correctly prior to the compilation step.
Enable NuGet on TeamCity through the Administration link
Add a NuGet install step prior to the compilation step
Hope this helps

Answer 2

This is probably a newbie paket mistake. Since we want to have automatic resolve of the packages when we build in Visual Studio we must add one line to our project files:
<Import Project="..\.paket\paket.targets" />
And it also important that this file is in the right place in the project file. If I had it above
<Import Project="$(FSharpTargetsPath)" />
it didn't work. So I put it right below and now everything works like a charm.
