Configurations and Projects/Colutions Oh My...

[DynConcepts]

The VS GUI allows you do delete a Solution config, but that does not iterate through projects. I want to delete "ALL" project configurations and platforms except for a specific one...

I can iterate through them and identify them, but can not find the object to call a "remove like" method on...

var allprojectConfigs = data.ProjectItemsConfigs.ToList(); List<ProjectItemCfg> toRemove = new List<ProjectItemCfg>(); foreach (ProjectItemCfg projectConfig in allprojectConfigs) { if (projectConfig.projectConfig.Platform == "x64") { Microsoft.Build.Evaluation.Project loadedProject = sln.Result.Env.GetOrLoadProject(projectConfig.project); toRemove.Add(projectConfig); } } // OK, now kill everything in the "toRemove" list"

[DynConcepts]

Additional info... This would also need to remove any other elements that were specific to the removed configuration/platform. At this point pretty sure that the package does not support this as a single call (but still hopeful), but perhaps someone has previously developed a snipped and can share.

NOTE: The Project Configuration/Platform most likely does NOT exist in the Solution!!!!!!

How about

using var sln = new Sln(@"D:\prg\issues\MvsSln\issue40\TestStruct\TestStruct.sln", SlnItems.Env);
sln.Result.Env
    .LoadProjects(sln.Result.ProjectItemsConfigs.Where(p => p.solutionConfig.Platform == "x64"))
    .ForEach(xp => // TODO: more like we need add this as part of MvsSln, https://github.com/3F/DllExport/blob/c1cc52fa13f563f97a2b4fe08bfb541c69195866/Wizard/Extensions/XProjectExtension.cs#L121
        xp.Project.Xml.PropertyGroups.Where(p =>
                // NOTE: projectConfig should contain default IRuleOfConfig impl to avoid misunderstanding between "Any CPU" and "AnyCPU", or like;
                // MS "Any CPU" bug was described here: https://github.com/3F/vsSolutionBuildEvent/issues/14#issuecomment-246419276
                p.Condition.Contains($"'{xp.ProjectItem.projectConfig.ConfigurationByRule}|{xp.ProjectItem.projectConfig.PlatformByRule}'")
        )
        .ForEach(p => p.Parent?.RemoveChild(p))
        .E(_ => xp.Save())
    );

NOTE: The Project Configuration/Platform most likely does NOT exist in the Solution!!!!!!

Make sure about the "Any CPU" / "AnyCPU". You can simply use the default rules or implement something for the mentioned IRuleOfConfig

This would also need to remove any other elements that were specific to the removed configuration/platform.

Just add something else together with PropertyGroups logic above

Attach demo project as example with you problem data and used structure because I don't see the problem when != "x64" at least for

.sln

GlobalSection(SolutionConfigurationPlatforms) = preSolution
	Debug|Any CPU = Debug|Any CPU
	Debug|x64 = Debug|x64
	Release|Any CPU = Release|Any CPU
	Release|x64 = Release|x64
	SomeSpec|Any CPU = SomeSpec|Any CPU
	SomeSpec|x64 = SomeSpec|x64
EndGlobalSection

Below has been removed from all project files due to p.solutionConfig.Platform != "x64"

<PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Debug|AnyCPU' ">...
<PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Release|AnyCPU' ">...
<PropertyGroup Condition="'$(Configuration)|$(Platform)' == 'SomeSpec|AnyCPU'">...

[DynConcepts]

No, I am talking about solution that only has

GlobalSection(SolutionConfigurationPlatforms) = preSolution
	Debug|Any CPU = Debug|Any CPU
	Release|Any CPU = Release|Any CPU
EndGlobalSection

With project that DO have...

<PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Debug|x64' ">
<PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Release|x64' ">

I will try to put together a sample, right now the solution I am working on has over 500 projects.

No, I am talking about solution that only has

Then there is nothing surprising about the result using the above logic.

This will remove any lost/broken configurations in all project files based on your .sln

// ... add this after my src from answer
sln.Result.Env.Projects.ForEach(xp => 
    xp.Project.Xml.PropertyGroups.Where(p => p.Condition.Contains("'$(Configuration)|$(Platform)'"))
    .Where(p =>
        sln.Result.ProjectItemsConfigs.All(s => 
            !p.Condition.Contains($"'{s.projectConfig.ConfigurationByRule}|{s.projectConfig.PlatformByRule}'")
        )
    )
    .ForEach(p => p.Parent?.RemoveChild(p))
);

// save once after ALL operations for better performance
sln.Result.Env.UniqueByGuidProjects.ForEach(xp => xp.Save());

[DynConcepts]

That sounds perfect. Will try it when I have a clean (no other pending changes) environment later today).
