ASP.NET 核心 MVC 应用程序见解在升级到 .NET Core 1.1.1 后停止工作
ASP.NET Core MVC application insights stopped working after upgrade to .NET Core 1.1.1
我在 2016 年 12 月开发了一个简单的 ASP.NET 核心应用程序。它在应用程序洞察和遥测方面运行良好。
现在 4 个月后我想接手这项工作并开始从 .NET Core 1.1.0 升级到 1.1.1。在此过程中，包 Microsoft.ApplicationInsights.AspNetCore 从版本 1.0.2 更新到版本 2.0.0。
不幸的是，这导致我的应用程序停止工作，特别是我收到此错误：
An error occurred during the compilation of a resource required to process this request. Please review the following specific error details and modify your source code appropriately.

屏幕：
从 project.json 升级到新的 csproj 并使用新的 Visual Studio 2017 没有帮助。
看起来 ApplicationInsightsJavaScript 基本上已从 API 中删除。那么如何启用 javascript 应用程序洞察力？
从 ApplicationInsights 1.x 到 2.x 有重大变化，记录在 GitHub release notes 上。
- This release contains a rewrite of the SDK internals for better .NET
Core integration and initialization.
UseApplicationInsightsRequestTelemetry is obsolete, the logic it used
to perform is handled automatically now and calls to this method
should be deleted from Startup.cs.UseApplicationInsightsExceptionTelemetry is obsolete, exception
telemetry is handled automatically internally now. You should delete
calls to this method from Startup.cs otherwise you will get duplicate
exception telemetry reported.- The MVC dependency for the JavaScript
snippet has been removed so in order to include the JavaScript snippet
now you need to make the following changes:
- In _ViewImports.cshtml replace
@inject Microsoft.ApplicationInsights.Extensibility.TelemetryConfiguration TelemetryConfiguration with @inject Microsoft.ApplicationInsights.AspNetCore.JavaScriptSnippet JavaScriptSnippet
- In _Layout.cshtml replace
@Html.ApplicationInsightsJavaScript(TelemetryConfiguration) with @Html.Raw(JavaScriptSnippet.FullScript)
