How to create a project configuration based on release?

William Liu 511

There are two default configurations Debug and Release for a dotnet csharp project.

I am trying to add a configuration which can perform some customization (custom propertys, build tasks, and so on).

<Configurations>Debug;Release;MyConfRel</Configurations>

I can build the project with the following to active "MyConfRel" configuration now.

dotnet build -c MyConfRel

Here are my two questions,

is the created "MyConfRel" based on a Debug configuration?
If Q1 is yes, then how to create a configuration based on Release configuration?

Hello @William Liu ,

Please check Viorel-1’s answer. Besides, following are some additional explanations:

Is the created "MyConfRel" based on a Debug configuration?

It depends on whether you selected Release/Debug for Copy settings from: option when you created your project configuration(MyConfRel). See following screenshot:

If you selected it, then the configuration(MyConfRel) is the same with Release/Debug. If you select <Empty> then your configuration is neither based on Debug nor based on Release, and it’s empty and waiting for you to set(you can customize the settings in the project property pages, see this document: Create a project configuration and Viorel-1's answer).

I create a Test (based on Empty) and Dev (based on Debug) configurations through the solution configuration manager for a Console project.

However, I did not see the distinct difference between the Test and Dev through the git diff.

I aslo create a Pub configuration based on Release, still not see the difference comparing to Test and Dev, except the predefined Constants (TEST, DEV, PUB). I did not find the Optimize flag was set for Pub configuration since it`s created from Release. Is there a configuration manager bug?

To make a new configuration that is similar to Release, I think that you should also add these lines:

<PropertyGroup Condition="'$(Configuration)|$(Platform)'=='MyConfRel|AnyCPU'"> <Optimize>True</Optimize> </PropertyGroup>

Actually, you can use the Visual, Studio, go to Project Properties and see the differences between configurations, but you should select the "Vary value by Configurations" option that appears for menues.

Thanks so much for the answer!

By the way, can I say the difference between Debug and Release default configurations is just about the DefineConstants and Optimize flag?

I think so.
