JetBrains Rider could not copy Azure.Function.Worker

When using JetBrains Rider to debug an Azure Function every other re-build/build I get the following error message:

Microsoft.Azure.Functions.Worker.Sdk.targets(169,9): Warning MSB3026 : Could not copy "C:*\Local\Temp\2n3kt121.jsm\buildout\bin\Microsoft.Azure.WebJobs.Extensions.FunctionMetadataLoader.dll" to "C:\Dev**\bin\Debug\

enter image description here

Then I have to look for a process 'func' and close it manually or close and re-open Rider to make it build again. This is very frustrating. Does anyone know a fix for this?

Solution

  • Microsoft.Azure.Functions.Worker.Sdk.targets(169,9): Warning MSB3026 : Could not copy "C:Local\Temp\2n3kt121.jsm\buildout\bin\Microsoft.Azure.WebJobs.Extensions.FunctionMetadataLoader.dll" to "C:\Dev\bin\Debug\

    To resolve this error, delete the Azure Function Tools folder under C:\Users\***\AppData\Local\ (as mentioned in the comments)=> restart the Rider IDE and run the function.

    • Navigate to the project root directory=> delete the bin and obj folders and rebuild the project, this forces Rider to clean and rebuild the entire project from scratch and resolves configuration issues if there is any.
    • Clear cache in Rider, navigate to File=>Invalidate Caches=>Invalidate Restart.

    • According to the screenshot provided in the question, the function seems to be isolated azure function.
    • Install all the required packages for your project.

    Isolated function:
