无法加载文件或程序集“Microsoft.AI.Web”或其依赖项之一。 系统找不到指定的文件

Question

After successfully publishing my Web Api to Azure when i try to hit the api i get the following error.

Here's a link to api

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value
[HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.

Note: There is some performance penalty associated with assembly bind failure logging. To turn this feature off, remove the registry value [HKLM\\Software\\Microsoft\\Fusion!EnableLog] .

Answer 1

I solved this problem by doing this:

Install-Package Microsoft.ApplicationInsights.Web

To install Application Insights only to the Web/API Project:

Install-Package Microsoft.ApplicationInsights.Web YourProjectName

To run these commands, in Visual Studio open Package Manager by clicking on: Tools -> NuGet Package Manager -> Package Manager Console

Answer 2

Using "Manage NuGet Packages" I tired to install Microsoft.ApplicationInsights.Web . It was already installed. I gave an "Update". After rebuild application, the error is gone.

Answer 3

I have reproduce this type issue. Here is my reproduce process:

1) Create web App api with Microsoft.ApplicationInsights.Web installed.
2) Then deploy the App to Azure Web app.

Here is the web API worked screenshot:

Then I open KUDU tool, delete Microsoft.AI.Web in Bin folder, and run the site again. I get the same error with you, here is the screenshot:

So I can ensure that, this error is caused by the assembly Microsoft.AI.Web is missing. Please set the copy local as true as following screenshot, then redeploy to Azure web App:

Answer 5

All the Answers about "Install-Package Microsoft.ApplicationInsights.Web" are not directly solved the Error in my case. My WebApplication-Project did not accept the Installing of the Package (Rollback after a few Minutes of installing).

Then I tried to add the NuGetPacke for Microsoft.ApplicationInsights.Web into a Library-Project, which my WebApplication use. That added the AI.Web-DLLs also to my WebApplication and solved the Problem.
