I always find it difficult to track .Net and C# language release history. E.g. what .net versions are released with different visual studio versions and what features are available in different versions of C# language. So I thought I will compile this information in this blog so I and other can refer it when needed.
Note:
- .Net 3.5, 3.0 and 2.0 uses same common language runtime version 2.0.
- .Net 4.5, 4.5.1 and 4.0 share same common language runtime version 4.0.
- I have not included language features in above list e.g. Partial classes / anonymous method. I will cover them in following section.
| .Net Version | Release Date | Tool | Feature |
|---|---|---|---|
| 1.0 | 2002 | Visual Studio .Net | First release of .net |
| 1.1 | 2003 | Visual Studio 2003 | Support for ASP.Net mobile controls Supports side-by-side execution Security Changes |
| 2.0 | 2005 | Visual Studio 2005 | Generics (with generic collection) Nullable Types Support of IPv6 addresses in .net remoting Common Language Runtime 2.0 |
| 3.0 | 2006 | – | WCF (Communication framework) WPF (Presentation framework) WF (Workflow Foundation) |
| 3.5 | 2008 | Visual Studio 2008 | LINQ Addin / Plugin Model (System.AddIn.Contract.dll) |
| 4.0 | 2010 | Visual Studio 2010 | Parallel Computing Code Contracts Lazy Initialization Dynamic Language Runtime In-process side-by-side hosting Background garbage collection Covariance and Contravariance Common Language Runtime 4.0 |
| 4.5 | 2012 | Visual Studio 2012 | Enhanced regular expression support Default culture for application domain Zip compression Support of array with size more than 2GB Asynchronous file operation Improvement in parallel computing |
| 4.5.1 | 2013 | Visual Studio 2013 | Ability to collect diagnostics information Ability to explicitly compact the large object heap (LOH) during garbage collection Additional performance improvements such as ASP.NET app suspension Multi-core JIT improvements |
