Can't run Functions v2 on OSX after update

[likwidgames]

Ever since I updated my packages to Microsoft.NET.Sdk.Functions 1.0.19, I can no longer test my builds in Visual Studio Mac. I am presented with the error below. I have tried updating my Visual Studio (stable, beta and alpha) but they don't seem to be updating the runtime version to 2.0.12x, so I'm stuck with 2.0.119, which is not supported with the latest version of the Functions Sdk.. Is there a way to manually do this?

similar error on my mac as well after an upgrade to the solution:

Note that this same project works on Visual Studio 2017 15.8.2 and version 15.8.5023 of the Azure Functions and Web Jobs Tools package.

Version 2.5.2 of the Azure Functions Cli tools is also installed for Windows.

I don't know how to updat the host version from that highlighted above to the latest version. I have tried following these instructions, for cli tools installation but this doesn't appear to have changed anything when running the function.

I'm getting this also. Has anybody found a fix for this yet ?

Also getting this issue after a fresh install of all tools. Local SDKS and Nuget packages upgraded to latest, but host still running the same version as above, bump?

I found this page
#3363

and

this page
Azure/app-service-announcements#129

My problem is the execution context issue. It's not obvious if I need to install all of these packages or just the ones I use

NuGet Package	Version
Microsoft.NET.Sdk.Functions	1.0.19
Microsoft.Azure.WebJobs.Extensions.CosmosDB	3.0.1-beta2
Microsoft.Azure.WebJobs.Extensions.DurableTask	1.6.0
Microsoft.Azure.WebJobs.Extensions.MicrosoftGraph	1.0.0-beta4
Microsoft.Azure.WebJobs.ServiceBus	3.0.0-beta8
Microsoft.Azure.WebJobs.Extensions.EventHubs	3.0.0-beta8
Microsoft.Azure.WebJobs.Extensions.SendGrid	3.0.0-beta8
Microsoft.Azure.WebJobs.Extensions.EventGrid	2.0.0-beta4
Microsoft.Azure.WebJobs.Extensions.Storage	3.0.0-beta8
Microsoft.Azure.WebJobs.Extensions.Twilio	3.0.0-beta8
Microsoft.Azure.WebJobs.Script.ExtensionsMetadataGenerator	1.0.0

I'm going to try all as the ExecutionContext might need to be aware of all possible triggers

I had the same similar issue:
System.Private.CoreLib: Could not load type 'Microsoft.Azure.WebJobs.Hosting.IWebJobsStartup' from assembly 'Microsoft.Azure.WebJobs.Host, Version=3.0.0.0, Culture=neutral, PublicKeyToken=null'.

I typed this command: npm install -g azure-functions-core-tools.

My current setup:

Azure Functions Core Tools: 2.0.3
Functions Runtime : 2.0.12115.0
Microsoft.NET.Sdk.Functions: 1.0.22
Microsoft.Azure.WebJobs.Extensions.CosmosDB: 3.0.1
Microsoft.Azure.WebJobs.Extensions.SendGrid: 3.0.0
Microsoft.Azure.Management.Fluent: 1.15.1

Ok got really fed up with this. I noticed there were some updates to Visual Studio Mac on the Alpha Channel for Azure functions. I downloaded the updates but it still didn't work.

I also re-installed Azure Functions Core Tools using brew

brew tap azure/functions
brew install azure-functions-core-tools

and still didn't help :/

I am mentioning the above as I don't know if they are pre-requisites to the next step that worked!

I then found this link

Azure/azure-functions-core-tools#697

And did this as suggested.

dotnet publish src/Azure.Functions.Cli/Azure.Functions.Cli.csproj --runtime osx-x64 --output /tmp/cli 

# then do
/tmp/cli/func start 

You have to copy over your local settings.json file and then it worked for me.

At this moment, it is possible to run the function project in VS code where Functions v2 are working on macOS. Unfortunately, currently, Functions Runtime =>2.0.12050 isn't working in Visual Studio Mac.
This is described in the following post: Azure/azure-webjobs-sdk#1905 (comment)

Is this still an issue?

[ossentoo]

No
