Error Occurs When Upgrading from Orleans 9.0.1 to 9.1.0

[ikpil]

When upgrading from Orleans 9.0.1 to 9.1.0 as follows, an error occurs.
How can I resolve this issue?

.csproj

    <PackageReference Include="Microsoft.Extensions.Hosting" Version="9.0.1" />

Having the same problem, exception Could not load file or assembly Orleans.Sdk thrown on startup

builder.Host.UseOrleans((context, siloBuilder) => { siloBuilder.SetupOrleans(orleansConfiguration, siloConfigurationVariables); siloBuilder.Services.AddOrleansGrainStorageSerializer(); siloBuilder.AddLogging(); });

Was working fine in 9.0.1

Uh oh. Does removing the reference to Microsoft.Orleans.Sdk work for you? We made a change so that it is effectively always referenced, but in doing so there may have been an issue with the final 'sdk' package (which is a meta package and should not include any DLL)

[zharchimage]

I have some Model Class Libraries with a reference to the Orleans.Sdk, this are referenced by all the silo projects witch don't have a direct reference to the Orleans.Sdk but instead on a transitive way. The Model library has GenerateSerializer and Alias everhwhere so if I remove that reference the project doesn't compile. Shall I install in that project Microsoft.Orleans.Core.Abstractions?

Yes, please try that. I will investigate the packaging issue in a few hours when it's morning here, and likely release an update.

Could you try removing the Orleans dashboard? I wonder if that is the cause of this? Meanwhile I am trying to reproduce the issue here

[zharchimage]

I don't have the dashboard package, in my case. Removed all tope level Orleans.sdk references, added the abstractions package with no luck. If it helps in my common library I have this packages:

<ItemGroup>
		<PackageReference Include="Microsoft.Orleans.Serialization.SystemTextJson" Version="9.0.1" />
		<PackageReference Include="Microsoft.Orleans.Persistence.AdoNet" Version="9.0.1" />
		<PackageReference Include="Microsoft.Orleans.Clustering.AdoNet " Version="9.0.1" />
		<PackageReference Include="Microsoft.Orleans.Sdk" Version="9.0.1" />
		<PackageReference Include="Microsoft.Orleans.Reminders.AdoNet" Version="9.0.1" />		
		<PackageReference Include="Microsoft.EntityFrameworkCore.Proxies" Version="9.0.1" />
		<PackageReference Include="Microsoft.EntityFrameworkCore.SqlServer" Version="9.0.1" />
		<PackageReference Include="MathNet.Numerics" Version="6.0.0-beta1" />		
	</ItemGroup>

And in my silo project wich references this common library:

	<ItemGroup>
	  <PackageReference Include="Microsoft.VisualStudio.Azure.Containers.Tools.Targets" Version="1.21.1" />
	</ItemGroup>

This configuration was working pre 9.1.0 update.

[ReubenBond]

I believe I'm narrowing in on the issue and, if I'm correct, we should have a fixed build available shortly.

[ReubenBond]

This issue affected the following packages:

• Microsoft.Orleans.Reminders.AzureStorage
• Microsoft.Orleans.Reminders.Cosmos
• Microsoft.Orleans.Reminders
• Microsoft.Orleans.Reminders.Redis
• Microsoft.Orleans.TestingHost
• Microsoft.Orleans.Transactions.TestKit.Base
• Microsoft.Orleans.Transactions.TestKit.xUnit

By extension, any project which pulls in Reminders or one of the other affected packages would be affected.

I've delisted the v9.1.0 releases of the above packages and packages which reference them.

[ReubenBond]

Hi all, Orleans v9.1.1 is now available on nuget.org (possibly still being indexed currently). Please try upgrading and let us know if it works for you. Thank you for your patience and please accept our apologies for the inconvenience.
