问题 .NET 5.0 will replace .NET Core 3.x when it is released in November—and, thus, ASP.NET 5.0 will replace ASP.NET Core 3.x. Edit: This question is based on a fundamentally incorrect assumption. While the next version of .NET Core will, in fact, be .NET 5.0, the next version of ASP.NET Core will be ASP.NET Core 5.0. See the answers from @Camilo-Terevinto and @omajid for details. Despite this, as of Preview 8 (8.20414.8), packages, assemblies, and namespaces still contain AspNetCore in their

问题 I have a little problem with single file executable publish with .NET 5. Infact, it does not include all libraries in the executable file, and produces multiple files. In my example I'm using a library for SQLite (Microsoft.Data.Sqlite) and, after compilation, e_sqlite3.dll is not included. Instead, in the output folder, it produces two files (excluding the pdb file): > e_sqlite3.dll > WpfApp1.exe 回答1: By reading documentation Single-file doesn't bundle native libraries by default. On Linux,

问题 I have a .NET Core solution which was running well using .NET Core 3.1 using a Pipeline on Azure Devops. Everything was working fine on the Pipeline. After moving from .NET Core 3.1 to .NET 5.0, I started to have some strange troubles running the pipeline, specifically with Nuget packages. I can build with no problems, but when it starts to pack using Nuget Package, I've got this error: [error] The nuget command failed with exit code(1) NU1202: Package Microsoft.EntityFrameworkCore 5.0.0 is

问题 I've upgraded an Asp.Net Core 3.1 (MVC) to .Net 5 by modifying the corresponding *.csproj file to this: <TargetFramework>net5.0</TargetFramework> <LangVersion>9.0</LangVersion> Now I can use the C# 9 target typing feature... string s = new('c', 3); // compiles fine ...but I can't create a record class: public data class User { // IDE1007 The name 'data' does not exist in the current context. } Am I missing something here? 回答1: According to record type specs, you should use public record User

问题 I was looking for some NuGet updates about my project libraries. I see that there are a lot of Microsoft libraries update to v5.0.0. Based on my knowledge I think these are new dependencies released with .Net 5.0 and I'm not sure that I can update these libraries to latest version using .Net Core 3.1 project. Can I update to v5.0.0 libraries even if I'm using/building a .Net Core 3.1 project? 回答1: Unfortunately, you cannot update many of these newest Nuget packages to 5.0. The reason being is
