Questions tagged [asp.net]
ASP.NET is a Microsoft web application development framework that allows programmers to build dynamic web sites, web applications and web services. It is useful to use this tag in conjunction with the project type tag e.g. [asp.net-mvc], [asp.net-webforms], or [asp.net-web-api]. Do NOT use this tag for questions about ASP.NET Core - use [asp.net-core] instead.
