重新加载 Web 项目时，Visual Studio 2019 值不在预期范围内 [英] Visual Studio 2019 Value does not fall within the expected range when reloading web project

问题描述

我刚刚升级到 VS2019 Pro.我正在设置新的 解决方案过滤器 功能，以允许我仅使用我正在处理的项目的依赖项部分加载我的解决方案，并在加载(或重新加载)ASP.Net MVC Web 时遇到问题项目.

I've just upgraded to VS2019 Pro. I was setting up the new Solution Filters feature to allow me to partially load my solutions with only the dependencies for the project I am working on and hit a problem loading (or reloading) an ASP.Net MVC Web Project.

请参阅此处:https://youtu.be/u5YauFxb2Ho?t=783

我所做的是关闭我的解决方案，然后转到新的起始页并选择打开项目或解决方案.

What I did was close my solution and then go to the new Start Page and select Open a project or solution.

然后浏览到解决方案的 *.sln 文件并勾选不加载项目"复选框，以便打开解决方案但不加载任何项目.

Then browse to the *.sln file for the solution and tick the "Do not load projects" checkbox so that the solution opens but no projects are loaded.

当我右键单击 Web 项目并选择重新加载项目"时，出现值不在预期范围内"错误.

When I right clicked the Web Project and chose "Reload Project" I got a "Value does not fall within the expected range" error.

推荐答案

结果(在查看输出窗口后 - 是的，我知道)问题是由于缺乏权限，VS 无法启动 IIS Express.

Turns out (after looking in the Output Window - yes, I know) the problem was that VS couldn't launch IIS Express due to a lack of permissions.

只需关闭并重新以管理员身份启动 VS2019，重新加载 Web 项目，这次 IIS Express 将启动，一切都会好起来的.

Just close and re-launch VS2019 as Administrator, re-load the Web Project and IIS Express will start this time and all will be well with your world.
