JetBrains.Annotations by: JetBrains

JetBrains.Annotations help reduce false positive warnings, explicitly declare purity and nullability in your code, deal with implicit usages of members, support special semantics of APIs in ASP.NET and XAML frameworks and otherwise increase accuracy of JetBrains Rider and ReSharper code inspections.

jnm2.ReferenceAssemblies.net35 by: Microsoft

A community answer to Microsoft’s decision to single out net35 by excluding it from the https://www.nuget.org/packages/Microsoft.NETFramework.ReferenceAssemblies/ package. This package provides the .NET Framework 3.5 reference assemblies so that net35 projects can be built using the dotnet CLI. Example project that targets multiple frameworks: <Project Sdk="Microsoft.NET.Sdk"> <PropertyGroup> <TargetFrameworks>net35;net40;netstandard2.0;netcoreapp3.0</TargetFrameworks> </PropertyGroup> <ItemGroup> <PackageReference Include="Microsoft.NETFramework.ReferenceAssemblies" Version="1.0.0" /> <PackageReference Include="jnm2.ReferenceAssemblies.net35" Version="1.0.1" /> </ItemGroup> </Project>

LinqBridge by: Atif Aziz

With Visual Studio's multi-targeting and LINQBridge, you can write LINQ to Objects (local) queries using the full power of the C# 3.0 compiler and yet create programs that require only Microsoft .NET Framework 2.0. LINQBridge is a re-implementation of all the standard query operators introduced with Microsoft .NET Framework 3.5's System.Linq.Enumerable class.

log4net by: The Apache Software Foundation

log4net is a tool to help the programmer output log statements to a variety of output targets. In case of problems with an application, it is helpful to enable logging so that the problem can be located. With log4net it is possible to enable logging at runtime without modifying the application binary. The log4net package is designed so that log statements can remain in shipped code without incurring a high performance cost. It follows that the speed of logging (or rather not logging) is crucial. At the same time, log output can be so voluminous that it quickly becomes overwhelming. One of the distinctive features of log4net is the notion of hierarchical loggers. Using these loggers it is possible to selectively control which log statements are output at arbitrary granularity. log4net is designed with two distinct goals in mind: speed and flexibility

lz4net by: Milosz Krajewski

LZ4 is lossless compression algorithm, sacrificing compression ratio for compression/decompression speed. Its compression speed is ~400 MB/s per core while decompression speed reaches ~2 GB/s, not far from RAM speed limits. LZ4net brings LZ4 to all (most?) .NET platforms: .NET 2.0+, .NET Core, Mono, Windows Phone, Xamarin.iOS, Xamarin.Android and Silverlight

ManagedEsent by: Microsoft

ManagedEsent provides managed access to ESENT, the embeddable database engine native to Windows. ManagedEsent uses the esent.dll that is part of Microsoft Windows so there are no extra unmanaged binaries to download and install.
