【问题描述】：
我目前正在开发一个 ASP.NET 核心/MVC 核心应用程序，但是当我第一次将项目加载到 Visual Studio 时，它需要很长时间才能加载（20 分钟）。
我不确定是什么导致加载时间延长，但它不是 Visual Studio 本身，因为其他项目加载速度更快，我很确定它与这个单独的项目有关，因为它曾经可以正常工作，并且我已经在另一台笔记本电脑上尝试过，它也需要时间。
我也尝试使用 /SafeMode 开关启动 Visual Studio，但这并没有什么不同。
我正在使用 Visual Studio 2015 企业版
下面是我的 project.json 的副本，以防有人发现它的潜在问题

编辑 12/17/17 00:30 GMT：
- 一个新的简单 ASP.NET CORE MVC 站点可以快速打开
- 我正在运行 Visual Studio 2015 Update 3
- 我在 Surface Pro 4 i7/16GB/512GB SSD 上运行它
- 我已在安全模式下运行 Visual Studio（devenv.exe /SafeMode 禁用了包括 ReSharper 在内的扩展，加载时间没有增加）
- 问题早于我添加 SendGrid 依赖项，因此与此无关。
- 我现在已更新到可用的最新工具 (dotnet-win-x64.1.1.0.exe)
我还应该提一下，我已经完成了以前最喜欢的关闭并重新打开它！

我想我可能已经弄清楚了原因，但不知道如何解决它。
我依稀记得在添加了一些 bower 依赖项后出现了问题，这可能是原因吗（我已尝试删除所有 bower 依赖项
我的 bower.json 文件目前看起来像
{
"name": "asp.net",
"private": true,
"dependencies": {
"bootstrap": "3.3.6",
"jquery": "2.2.0",
"jquery-validation": "1.14.0",
"jquery-validation-unobtrusive": "3.2.6",
"font-awesome": "4.6.1",
"admin-lte": "*",
"material-design-icons": "2.2.3",
"startbootstrap-creative": "3.3.7"
}
}
我刚刚将它添加到我的新模板解决方案中，并且包还原需要时间。所以我想知道 Visual Studio 是否将凉亭还原作为打开解决方案的一部分？
【问题讨论】：
-
也许这不是一个解决方案，更像是一个建议，你可以忽略它。但我认为您可能想购买 SSD 驱动器。我发现它的性能改进更好
-
您是否尝试在控制台中运行
dotnet build？ -
@HungCao 它已经在 SSD 驱动器上，在带有 i7 处理器和 16GB 内存的 Surface Pro 4 配置上。
-
@Kalten 这不是构建花费时间，构建在 VS 和控制台中运行良好且快速（输出显示构建在 00:00:09.8916456 完成）它实际上是文件->打开加载需要 20 分钟的解决方案。
