Can't pass msbuild params in `dotnet run`

Steps to reproduce

I can’t pass msbuild params from dotnet run command. I can use

dotnet restore /p:PARAM=1 solution.sln
dotnet build /p:PARAM=1 solution.sln

but can’t write dotnet run /p:PARAM=1 soluition.sln because these params are not passed to msbuild.

Expected behavior

msbuild params are passed to msbuild.

Actual behavior

msbuild params are not passed to msbuild.

Environment data

dotnet --info output:

What’s the priority of this?

For consistency, if dotnet run will automatically kick off a dotnet build equivalent, then it ought to support passing the parameters dotnet build can accept.

I don’t think it’s entirely accurate to say that “dotnet run don’t have build involved other than to ensure the project is built already.” Lets say you had a msbuild project parameter that was necessary for a build to complete successfully, for example a relative path to a referenced project (probably not a best practice, but just a contrived example):

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <TargetFramework>netcoreapp1.1</TargetFramework>
    <AssemblyName>Example</AssemblyName>
    <OutputType>Exe</OutputType>
    <PackageId>Example</PackageId>
    <PackageTargetFallback>$(PackageTargetFallback);dnxcore50</PackageTargetFallback>
    <RuntimeFrameworkVersion>1.1.1</RuntimeFrameworkVersion>
  </PropertyGroup>

  <ItemGroup>
    <ProjectReference Include="$(PathToDep)/MyDependency.csproj" />
  </ItemGroup>

</Project>

This builds fine with dotnet build /p:PathToDep=../../my-dep-folder and running the build binary with dotnet bin/Debug/Example.dll also works fine, but there is no way to run this with dotnet run without modifying the csproj. When dotnet run is invoked without the parameter I get a bunch of missing reference errors and The build failed. Please fix the build errors and run again.

Also, regarding confusing argument passing there is already precedence for this because dotnet run accepts configuration and framework options (i.e. Debug vs Release). When it is necessary to disambiguate between options passed to dotnet run vs options passed to the project being run the double hyphen is used (from the dotnet run usage: dotnet run [options] [[--] <additional arguments>...]]), for example: dotnet run -c Release -- -c "look my command takes dash c too"

I think this issue should be reopened.
