无法加载文件或程序集'Microsoft.Azure.CosmosDB.BulkImport，版本= 2.0.0.0

Question

At the runtime, I keep running into this issue:

Could not load file or assembly 'Microsoft.Azure.CosmosDB.BulkImport, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies.

I believe BulkImport comes from the BulkExecutor package, and I can find BulkExecutor package in packages.config :

  <package id="Microsoft.Azure.CosmosDB.BulkExecutor" version="1.1.0" targetFramework="net462" />

But I cannot find the Microsoft.Azure.CosmosDB.BulkImport mentioned in neither packages.config nor app.config .

I can, however, find Microsoft.Azure.CosmosDB.BulkImport.dll in \\src\\packages\\Microsoft.Azure.CosmosDB.BulkExecutor.1.1.0\\lib\\net451\\

and this is referenced in .csproj file.

I tried clearing the bin folder, clean/build project, uninstalling and reinstalling BulkExecutor library, rebooting Visual Studio 2015, but did not work.

I'm using VS 2015, Microsoft.Azure.CosmosDB.BulkExecutor v.1.1.0, .NET Framework v.4.6.2, Microsoft.Azure.DocumentDB v.2.0.0 and Newtonsoft.Json v.10.0.2.

But I cannot find the Microsoft.Azure.CosmosDB.BulkImport mentioned in neither packages.config nor app.config.

Download the nuget package , rename it to microsoft.azure.cosmosdb.bulkexecutor.1.1.0.zip then you can check the content.

You'll find the Microsoft.Azure.CosmosDB.BulkImport.dll is part of the Microsoft.Azure.CosmosDB.BulkExecutor nuget package. When you reference the Microsoft.Azure.CosmosDB.BulkExecutor package in packages.config file, you're actually referencing the Microsoft.Azure.CosmosDB.BulkImport.dll .

And as I know, the normal Hintpath for packages.config format in xx.csproj should be something like:

<HintPath>..\packages\Microsoft.Azure.CosmosDB.BulkExecutor.1.1.0\lib\net451\Microsoft.Azure.CosmosDB.BulkImport.dll</HintPath>

At the runtime, I keep running into this issue:

So the compile and build succeeded, this issue only occur in runtime? If so, please check whether the Microsoft.Azure.CosmosDB.BulkImport.dll is in your output folder.(Usually bin folder).

For your error message, maybe your assembly can't find the Microsoft.Azure.CosmosDB.BulkImport.dll it referenced if the assembly wasn't copied to output folder.You can click the Microsoft.Azure.CosmosDB.BulkImport.dll in Solution Explorer , then set Copy Local to true in Properties Window .

If the issue persists though the Microsoft.Azure.CosmosDB.BulkImport.dll and your assembly or executable are in same folder, maybe you have a similar situation like this issue . The issue could result from your code, it'll be better if you could share some simple code in your question to reproduce it.
