Pitfall: using var and async together

The article details a common C# programming pitfall where using the 'var' keyword with an asynchronous method call (without an 'await') incorrectly stores a Task<T> instead of the result. This causes logical errors, as the Task is never null. It explores why compilers and analyzers miss it, suggests enabling nullable reference types in C# 8+, and emphasizes the importance of unit tests to catch such issues.
