Someone confuse about the .NET version and C# programming language version in someday. Remember that: .NET is Framework which was created by Microsoft to build platform like web service, application,…. You can write .NET apps in C#, F#, or Visual Basic. C# is a simple, modern, object-oriented, and type-safe programming language.
| Target framework | version | C# language version default |
|---|---|---|
| .NET | 7.x | C# 11 |
| .NET | 6.x | C# 10 |
| .NET | 5.x | C# 9.0 |
| .NET Core | 3.x | C# 8.0 |
| .NET Core | 2.x | C# 7.3 |
| .NET Standard | 2.1 | C# 8.0 |
| .NET Standard | 2.0 | C# 7.3 |
| .NET Standard | 1.x | C# 7.3 |
| .NET Framework | all | C# 7.3 |
In the above table they named this new release .NET 5 instead of .NET Core 4 for two reasons:
ASP.NET Core 5.0 is based on .NET (core) 5 but retains the name "Core" to avoid confusing it with ASP.NET MVC 5. Likewise, Entity Framework Core 5.0 retains the name "Core" to avoid confusing it with Entity Framework 5 and 6.
It’s C# 10 based on .NET 7 but C# version 11 will be released in November 2022 together with . NET 7.
