.NET 4.0 introduced System.Diagnostics.Contracts , allowing design-by-contract programming. Developers could specify preconditions, postconditions, and invariants statically checked by a runtime analyzer—improving reliability, especially in safety-critical systems. net. framework 4.0
The CLR in .NET 4.0 introduced in-process side-by-side execution, allowing different versions of the same application domain to run simultaneously within a single process.
