Command line building dotnet

I have the following project file :

XML

...
    <PropertyGroup Condition="'$(Configuration)|$(Platform)'=='Debug|AnyCPU'">
        <DefineConstants>TRACE;DEBUG;NETSTANDARD2_0; NET4;</DefineConstants>
        <OutputPath>..\output\</OutputPath>
        <AllowUnsafeBlocks>true</AllowUnsafeBlocks>
        <Optimize>false</Optimize>
    </PropertyGroup>
    <PropertyGroup Condition="'$(Configuration)|$(Platform)'=='Release|AnyCPU'">
        <DefineConstants>NETSTANDARD2_0; NET4;</DefineConstants>
        <AllowUnsafeBlocks>true</AllowUnsafeBlocks>
        <Optimize>true</Optimize>
        <OutputPath>..\output\</OutputPath>
    </PropertyGroup>
...

When running the following command :

dotnet build -c Release proj.sln

The optimize property is not used and is as if the Debug configuration is used.

What I have tried:

The only way is setting the <Optimize>true</Optimize> in the debug config, which defeats the purpose of it.

I don't follow you - how are you determining that it "is as if the Debug configuration is used" and the only way to what is setting optimize true in the debug config - surely that does nothing to the Release config at all?? Do you get the same problem with dotnet publish?

Mehdi Gholam 11-Nov-20 9:28am

The output file sizes differ (smaller) with optimize on.

Not necessarily. Perhaps it's also including debug info?
You can have both optimized and full debug info, they are not mutually exclusive.

Mehdi Gholam 11-Nov-20 10:23am

The execution is also slower.

PIEBALDconsult 11-Nov-20 10:26am

Then perhaps you have other issues.

PIEBALDconsult 11-Nov-20 10:31am

Maybe it isn't using either of those and is using only the defaults?

Mehdi Gholam 11-Nov-20 10:32am

Then how come when you set the debug config it works?

Try adding NDEBUG to the DefineConstants section of the release settings. No guarantee, but I know that is used in some project settings.

Mehdi Gholam 12-Nov-20 5:35am

nope, still the same.

Richard MacCutchan 12-Nov-20 5:36am

Yes, it was a long shot.

Mehdi Gholam 12-Nov-20 5:38am

I posted an issue to MS on github yesterday, waiting for a reply.

Richard MacCutchan 12-Nov-20 5:42am

Looking through the output above, I do not see any actual compilations taking place. Most items appear to be skipped as all files are up to date. Try changing some files or cleaning all the targets.

Mehdi Gholam 12-Nov-20 10:21am

Using the project file

dotnet build -c Release fastJSONCore.csproj

works!

Richard MacCutchan 12-Nov-20 10:30am

Well now you are the expert. :)

Mehdi Gholam 13-Nov-20 9:59am

Found the problem, posted the solution.

Finally found the problem, in your solution file you should configure the ProjectConfigurationPlatforms section to build Release and not Debug when the active configuration is set.

XML

...
        GlobalSection(SolutionConfigurationPlatforms) = preSolution
		Debug|Any CPU = Debug|Any CPU
		Release|Any CPU = Release|Any CPU
	EndGlobalSection
	GlobalSection(ProjectConfigurationPlatforms) = postSolution
		{32DBA62B-6F46-423F-9A2E-05CF451B0BAD}.Debug|Any CPU.ActiveCfg = Debug|Any CPU
		{32DBA62B-6F46-423F-9A2E-05CF451B0BAD}.Debug|Any CPU.Build.0 = Debug|Any CPU

		{32DBA62B-6F46-423F-9A2E-05CF451B0BAD}.Release|Any CPU.ActiveCfg = Release|Any CPU  <!-- here -->
		{32DBA62B-6F46-423F-9A2E-05CF451B0BAD}.Release|Any CPU.Build.0 = Release|Any CPU  <!-- here -->
	EndGlobalSection
