TNValidate - A Fluent Validation Library for .NET(tnvalidate.codeplex.com)

submitted by pheaven(430) 2 years, 9 months ago

TNValidate is a fluent validation library for .Net. It allows you to write validation logic in a form that is readable both by programmers and non-programmers, but still entirely in your .Net language. TNValidate has plenty of built-in validation rules, but also provides an extension mechanism to allow you to easily add your own without having to modify the library itself. The library is released under the MIT License. read more...

When Linq and ref Parameters Meet(programmersheaven.com)

submitted by pheaven(430) 3 years, 10 months ago

In this post we look into a curious quirk of C#: you can't use parameters passed as "ref" inside a Linq query (or a lambda expression or anonymous method either). By analysing the intermediate code produced by the C# compiler, we learn how anonymous methods are compiled when they need lexical scoping semantics. Finally, an attempt to change the IL to get the desired semantics reveals why C# forbids this. read more...
