Update https://github.com/dotnet/dotnet/blob/main/src/aspnetcore/src/Framework/test/TestData.cs I suspect most references in project files and targets in https://github.com/dotnet/dotnet/blob/main/src/aspnetcore can be removed as there are no special cases for things that come from the base shared framework (like System.Runtime). I reviewed everything in this search https://github.com/search?q=repo%3Adotnet%2Fdotnet%20Microsoft.Extensions.Hosting%20path%3A%2Fsrc%2Faspnetcore%2F**%2F*%20language%3Axml&type=code and it all looks to me like it can be cleaned up. I also see many other places across repos where tools or other components are built with @copilot please address feedback. |

All addressed in 73ab4fb:
Left Dependencies.props as is per your comment about waiting for pruning warnings to identify what needs cleanup. |

@copilot -- what about all the references in aspnetcore? https://github.com/search?q=repo%3Adotnet%2Fdotnet%20Microsoft.Extensions.Hosting%20path%3A%2Fsrc%2Faspnetcore%2F**%2F*%20language%3Axml&type=code These should all be cleaned up, along with any similar references to Extensions libraries which moved down. They'll all be automatically referenced since they are part of the base shared framework. |
Remove explicit package references to Microsoft.Extensions packages that have been moved to the base shared framework (Microsoft.NETCore.App). These packages are now automatically referenced from the base framework. Cleaned up 333 files across aspnetcore including: - eng/Dependencies.props - All .csproj, .props, and .targets files with references to moved packages Packages with references removed (35 total): - Caching: Abstractions, Memory - Configuration: Core + 9 providers (Binder, CommandLine, EnvironmentVariables, FileExtensions, Ini, Json, UserSecrets, Xml, Abstractions) - DependencyInjection: Core, Abstractions - Diagnostics: Core, Abstractions - FileProviders: Abstractions, Composite, Physical - FileSystemGlobbing - Hosting: Core, Abstractions - Http - Logging: Core + 6 providers (Abstractions, Configuration, Console, Debug, EventLog, EventSource, TraceSource) - Options: Core, ConfigurationExtensions, DataAnnotations - Primitives Kept references for ASP.NET Core-specific packages not moved to base framework: - Microsoft.Extensions.Diagnostics.Testing - Microsoft.Extensions.Diagnostics.HealthChecks* - Microsoft.Extensions.FileProviders.Embedded - Microsoft.Extensions.Caching.Hybrid/SqlServer/StackExchangeRedis - Microsoft.Extensions.Http.Polly - Microsoft.Extensions.Logging.AzureAppServices - Microsoft.Extensions.Configuration.KeyPerFile Co-authored-by: ericstj <8918108+ericstj@users.noreply.github.com>
Fixed in 950e8af - removed explicit package references to all 35 moved Microsoft.Extensions packages from 333 aspnetcore project files. These packages are now automatically referenced from the base shared framework. Kept references only for ASP.NET Core-specific packages that weren't moved (Diagnostics.Testing, HealthChecks*, FileProviders.Embedded, Caching.Hybrid/SqlServer/StackExchangeRedis, Http.Polly, Logging.AzureAppServices, Configuration.KeyPerFile). |

Ooh, interesting - what was the motivation for this? |
Reduce dependency bloat for libraries that rely on primitives like Microsoft.Extensions.Logging.Abstractions. This change would simplify dependency graphs, improve servicing, and reduce binary duplication in applications. I have a doc with data and measurements I'll share with you. |
|
@copilot -- it looks like you need to fix up all the Microsoft.Extensions projects in runtime. When a project becomes part of the shared framework it needs to declare all of its direct dependencies with Have a look at dotnet/src/runtime/src/libraries/System.Text.Json/src/System.Text.Json.csproj Lines 420 to 436 in b0ed06e You can determine which references to add by looking either looking at the assembly references present in the built binaries, or just iterate on adding to fix the build errors (might take a while). Try not to add any unnecessary dependencies. You can do a lightweight build of these projects using |
I understand the requirement. Adding conditional ProjectReferences for NetCoreAppCurrent to ~60 src/ref projects across 35 packages is a large task. Given the scope, would you prefer:
I can determine dependencies by analyzing existing PackageReferences and ProjectReferences in each project file. Should I proceed with option 1 or 3? |
|
@copilot If I were doing the task, I'd just write a script to dump simple name references of the file. For each simple name reference I'd ensure the project had a ProjectReference to represent that. After building one project you can actually find previously compiled versions of these files in the sdk that is downloaded. Reference assemblies are in: Just go at it to fix all of them at once. |

Woohoo! Made it through product build + phase1 source build! The next set of failures are phase2 pruning errors. We could remove those package references for source-build but it will break non-source build which still uses the older targeting packs. @ViktorHofer -- what do you think about disabling pruning warnings in phase 2 and deferring those fixes for backflow/rebootstrapping when they can be done without a sourcebuild-only condition? Additionally -- for other reasons I'm planning to change the scope of this PR to only a few assemblies. I wanted to take this one as far as I could, but I think now is a good point to switch to the smaller assembly set. |
|
Isn't this going to increase the size of netcoreapp? |
|
Will we have an announcement about this? It's a significant change. |
Whatever we do here, let's find a solution that works in the future as well when additional assemblies get absorbed into the shared framework. There are three layers in play here for which I have different perspectives: Shared framework repositoriesThese should use have a live PackageOverrides.txt file available at restore time and hand to that the sdk via the This will ensure that in both stage1 and stage2, packages that get absorbed into the shared framework can be removed. Btw, shared framework repos should now also opt into Downstream repositories (which depend on runtime assets)With your other change, all downstream repositories that depend on runtime assets now use the live targeting pack and with that receive the live PackageOverrides.txt file. So, in both stage1 and stage2 the packages can be removed when targeting the latest TFM. Repositories that build before runtime (and depend on runtime assets)That's the layer that is currently failing in this PR. There's not a good for answer for those, IMO. Conditionally referencing the packages based on stage1 vs stage2 creates a rift that the source-build team always tries to avoid. To be clear, the repositories affected are the VMR orchestrator and (transitive) runtime repo dependencies: SBRP, Arcade, command-line-api and cecil. Disabling package pruning in stage2 and then later after a re-bootstrap re-enabling it is an option. That's quite manual though. We could also add Hope that helps... |
Yes for the runtimepacks - however corresponding aspnet packs will shrink by the same amount. The total size of CLI install will decrease due to removal of duplicate assemblies in the SDK and tools. No change for folks who enable linker and don't use anything in these packages. Still it's a growth for some who don't use the linker nor use these packages today. A tradeoff. The same folks see growth for every feature we add to the framework. As I mentioned I'm adjusting the scope - I kept this PR going to get to the end of onion peeling and understand the changes needed to make these types of breaks in the VMR.
Of course. I've been talking about this change in our internal backlog reviews for nearly 6 months now.
I'm not sure they do. I think they only have those after restore since the SDK will go down the PackageDownload route for acquiring the targeting packs. The only reason we see this in early repos in phase2 is that those are the very first repos that build with the new targeting pack before restore (and thus with pruning data). |
The sdk is now constructed via symlinks. @MichaelSimons can provide more details
That comment was for shared framework repos. They construct a live PackageOverrides.txt file and it would be ideal of that would already be available at repo restore time. |
See the deduplication one pager for details. FYI, the implementation is currently scoped to content within the sdk folder. |
|
I don’t understand: what is the plan for users of self-contained apps with no ASP reference? How can they avoid a regression? |
|
Symlinks won't accomplish the same things since the SDK will not symlink to the ASP.NET shared framework (binaries might even differ due to crossgen differences). It'd still carry copies of things app-local. Also those can't be represented in the Zip, nor in MSIs (unless we're talking about adding custom actions here). I see @MichaelSimons paper calls this out. Net-net even in light of deduplication efforts (which are great!) moving these down will still reduce the size of the SDK -- just as it will reduce the size of folks building non-ASP.NET fx-dependent applications using ME, Aspire, MEAI, etc.
I see - so consumption of the same shared framework built in that repo. I'm not worried about that for this change since we already handle minimizing references to things in runtime built against shared framework. I don't expect many hits on those. You also mentioned downstream repos -- I don't see a way to have them pick up live pruning data unless we do a "pre-restore" of the targeting packs, or explicitly stage those into the SDK's packs folder. This feels like too much complexity for something that we can just "no-warn" and peel off into follow up PR. I'll see how much of a problem this actually is after reducing the set as I've already mentioned.
@agocke as I've mentioned it's a tradeoff. Any feature addition to the framework grows the size of the framework for people not using that feature. Where does the line get drawn? For folks who really care about size we have the linker. Everything moved here would be linked out if not used. We don't have promises around the size of self-contained apps that don't use the linker between major versions of a release. They see growth (regression) with pretty much every release. Size of self-contained hello-world across different framework versions
Reducing the size/technology-count/build-reference-count growth was one of the reasons I mentioned above that I'm dialing this back since I don't think all the side-effects outweighed the benefits. I've been more concerned with the build perf and technology prolifieration since folks can mitigate runtime pack size growth with linker -- but you are right to raise it as it does impact some. The size of the a few of the options being considered is as follows - measuring cross-gened size for RIDs, app-local files for IL, counts are runtime files but are mostly of the same order as reference files. Size of proposed assembly set moves
