# Polly vs aspnetcore

Polly and aspnetcore share 4 technologies: Microsoft.Extensions.Caching.Memory, System.ComponentModel.Annotations, Microsoft.Extensions.Logging.Console, and Microsoft.Extensions.Logging.Abstractions. Both are written in C#.

- [App-vNext/Polly](https://seerepo.com/r/App-vNext/Polly): Polly is a .NET resilience and transient-fault-handling library that allows developers to express policies such as Retry, Circuit Breaker, Timeout, Bulkhead Isolation, and Fallback in a fluent and thread-safe manner. From version 6.0.1, Polly targets .NET Standard 1.1 and 2.0+.
- [dotnet/aspnetcore](https://seerepo.com/r/dotnet/aspnetcore): ASP.NET Core is a cross-platform .NET framework for building modern cloud-based web applications on Windows, Mac, or Linux.

## What they share and what sets them apart

- In common: Microsoft.Extensions.Caching.Memory, System.ComponentModel.Annotations, Microsoft.Extensions.Logging.Console, Microsoft.Extensions.Logging.Abstractions
- Only in Polly: System.ValueTuple, Microsoft.Extensions.Options, System.Diagnostics.DiagnosticSource
- Only in aspnetcore: Blazor, Microsoft.AspNetCore.Components.Web, ASP.NET Core, Microsoft.Data.SqlClient.Extensions.Azure, Microsoft.EntityFrameworkCore.Sqlite, Microsoft.EntityFrameworkCore.SqlServer, Microsoft.Extensions.Caching.Abstractions, MySqlConnector, Npgsql.EntityFrameworkCore.PostgreSQL, Redis, Postgres, Microsoft.Data.SqlClient, MySQL, Grpc.AspNetCore, Microsoft.Extensions.Hosting, Microsoft.EntityFrameworkCore.Design, Microsoft.EntityFrameworkCore.Relational, Pomelo.EntityFrameworkCore.MySql, Microsoft.EntityFrameworkCore, Azure.Identity, Microsoft.IdentityModel.Protocols.OpenIdConnect, System.IdentityModel.Tokens.Jwt, @azure/msal-browser, Microsoft.Extensions.AI.Abstractions, Microsoft.Extensions.AI.OpenAI, Microsoft.Extensions.AI, AngleSharp, Microsoft.Extensions.Hosting.Abstractions, Microsoft.Extensions.Logging.Debug, OpenTelemetry.Exporter.OpenTelemetryProtocol, OpenTelemetry.Instrumentation.AspNetCore, OpenTelemetry.Instrumentation.Http, org.slf4j:slf4j-api, Microsoft.Extensions.Logging, OpenTelemetry, Serilog.Sinks.File

- Size: Lines written by people and agents, without generated ones; code files, without tests.
- Who writes it: A commit counts as AI's when it carries its signature: a Co-Authored-By line, its author name or the merge of its branch.
- Activity: From GitHub and its history, on the day SeeRepo read it.
- Tests: The files that test the code, and the share of code files a test imports.
