This can't be done with the standard library. It's quite common for people who want to do this to define their own extension method public static void Foreach<T>(this IEnumerable<T> it...
C# language version 8.0 introduces limited support for static methods, operators, etc. in interfaces. However, there are still limitations. I was hoping to use the new language features to try a ge...
The short answer is that it can't be done. C# doesn't support type functions. https://github.com/dotnet/csharplang/issues/339 is probably the issue to follow if you want to track their progress. W...
Interpreters are easier to write than compilers. For this reason esoteric and toy languages are often implemented by interpretation. But the dichotomy between interpreted and compiled languages is...

Problem I'm trying to update some projects from old-style .csproj: <?xml version="1.0" encoding="utf-8"?> <Project ToolsVersion="14.0" DefaultTargets="Build" xmlns="http://schemas.mi...
To whether the tag is useful: no. It's useful for tagging people ("this person does frontend and backend") but not questions. I don't see the point of adding "do not use": just delete the tag, whi...
This doesn't answer the question in full generality, but the assumption made seems reasonable to me: match lines containing (x1=y2;|c5=c6;) twice. I.e. ^(([^;]+; )*(x1=y2;|c5=c6;) ?){2}
By forking MSBuildLocator and basically just removing the #ifdef it's straightforward to list the available VS instances. It even works to register one, although if you want the same application to...
Microsoft.Build.Evaluation.Project seems to have some rather odd ideas of what values to use when loading projects. In particular, I have a number of projects with the following dependency: <Pa...
Tags also serve for someone who stumbles across the question directly from a third party link to find related content. Perhaps the child tag would suffice if the parent tag is automatically inserte...
echo "Enter Latitude\n"; $handle = fopen("php://stdin", "r"); $lat = deg2rad(trim(fgets($handle))); fclose($handle); echo "Enter Longitude\n"; $handle = fopen("php://stdin", "r"); $long = deg2rad(...
This is a class from my personal code library, and from a package which deals with integer sequences. It implements an interface package org.cheddarmonk.math.sequence; public interface IntegerSequ...
