I have the following project file :
    <PropertyGroup Condition="'$(Configuration)|$(Platform)'=='Debug|AnyCPU'">
        <DefineConstants>TRACE;DEBUG;NETSTANDARD2_0; NET4;</DefineConstants>
    <PropertyGroup Condition="'$(Configuration)|$(Platform)'=='Release|AnyCPU'">
        <DefineConstants>NETSTANDARD2_0; NET4;</DefineConstants>

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?

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.

The execution is also slower.

Then perhaps you have other issues.

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.
        GlobalSection(SolutionConfigurationPlatforms) = preSolution
		Debug|Any CPU = Debug|Any CPU
		Release|Any CPU = Release|Any CPU
	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 -->

They do like to make it easy don't they?
