MSBuild --no-restore cli argument is not available despite a DoRestore option

[Danl2620]

Description

Using the DotNet.build or DotNet.build it is not possible to pass through the --no-restore flag, despite the MSBuild.CliArguments type having a DoRestore member.

Repro steps

Create a build target like so:

Target.create "Build" (fun _ ->
    !! "TestProject 
    |> DotNet.publish (fun (info:DotNet.PublishOptions) -> 
        { info with
            MSBuildParams = { 
                MSBuild.CliArguments.Create() with 
                    DoRestore = false
            }
        })
)

Expected behavior

The build process would not do a restore before building.

Actual behavior

The build process does a restore.

Known workarounds

None that I am aware of.

You can set it as a MSBuild param. Thats the way I use it

Can you give an example? I'm not seeing a way in the source...

I think this particular edge case is a bit of a pain.
Afaik when using the msbuild cli then --no-restore is the default and you need to use /restore to enable restore.
When using the dotnet cli its exactly the reverse. It will use /restore by default and skip it if --no-restore is given.
Therefore, I feel like we need to add --no-restore to the dotnet cli instead of adding it to MSBuildParams. We can either add it to DotNet.Options

But I don't think you can use --no-restore on all commands. Therefore it needs to be added to every command manually. We already have this for dotnet test but need to add it to others:

By the way current way to do this is to use the Common.CustomParams field:

Thanks! I used withCustomParams and my particular case is solved:

Target.create "Build" (fun _ ->
    !! "TestProject 
    |> DotNet.publish (fun (info:DotNet.PublishOptions) -> 
        { info with
            Common = DotNet.Options.withCustomParams ("--no-restore" |> Some) info.Common
        })
)
