How to reference ASP.NET Core 6 types in .NET 6 library?
.net-core, asp.net-core, c#, libraries, package
Solution
You need to add a `FrameworkReference` to your project file instead of a `PackageReference` as described here.
<ItemGroup>
<FrameworkReference Include="Microsoft.AspNetCore.App" />
</ItemGroup>
Right-click your project in the Solution Explorer and select "Edit Project File" to open the file and look for the `<ItemGroup>` section, creating a new one if it does not exist.
Problem
I am working on internal libraries for my organization. I need to reference certain types that normally "belong" to web apps, eg. to provide some extensions: - `WebApplicationOptions` - `HttpContext` If I use `<Project Sdk="Microsoft.NET.Sdk">`, i don't have references to these types and can't find any nuget package which contains them. If i use `<Project Sdk="Microsoft.NET.Sdk.Web">`, i can't build my class library because it is treated as application and has to specify entry point. So, my question in general: what is the right way to write libraries for ASP.NET Core 6? Back in core 2.x days there were packages for everything, like `Microsoft.AspNetCore.Http.Abstractions`. They are all stuck at version `2.2.0` and i assume they're not usable now?
