Web deployment task failed. (The type initializer for 'Microsoft.Web.Deployment.DeploymentManager' threw an exception.)

We’re seeing this error on some machines but not others. Error:

O:\.NetCoreCache\sdk\3.1.200\Sdks\Microsoft.NET.Sdk.Publish\targets\PublishTargets\Microsoft.NET.Sdk.Publish.MSDeployPackage.targets(84,5): Web deployment task failed. (The type initializer for 'Microsoft.Web.Deployment.DeploymentManager' threw an exception.) [X:\bt\1110002\repo\src\Samples\WebSdkPackage\WebSdkPackage.csproj]

This task comes from the .NET SDK here:

O:\.NetCoreCache\sdk\3.1.200\Sdks\Microsoft.NET.Sdk.Publish\targets\..\tools\net46\Microsoft.NET.Sdk.Publish.Tasks.dll

With these dependencies:

Package/Publish task Microsoft.NET.Sdk.Publish.Tasks.MsDeploy.VSMSDeploy load assembly Microsoft.Web.Deployment, Version=9.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35
Package/Publish task Microsoft.NET.Sdk.Publish.Tasks.MsDeploy.VSMSDeploy load assembly Microsoft.Web.Delegation, Version=7.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35

On working machines, we see these DLLs in the package:

• Microsoft.NET.Sdk.Publish.Tasks.dll
• Microsoft.Web.Delegation.dll
• Microsoft.Web.Deployment.dll
• Microsoft.Web.XmlTransform.dll

On working machines, this DLL is also pulled in (via fusion logs):

Microsoft.Web.Deployment.Tracing

LOG: Found assembly by looking in the GAC.
LOG: Binding succeeds. Returns assembly from C:\WINDOWS\Microsoft.Net\assembly\GAC_MSIL\Microsoft.Web.Deployment.Tracing\v4.0_9.0.0.0__31bf3856ad364e35\Microsoft.Web.Deployment.Tracing.dll.
LOG: Assembly is loaded in default load context.

So this guy is coming in from the GAC in the successful case.

Since .NET Core is supposedly portable and xplat, I’m not sure why anything would depend on the GAC…

@vijayrkn Are we still waiting on the IIS team?

[vijayrkn]

yes, Agreed.

When WebDeploy was updated to work with mono, WebDeploy team only provided us with these 2 dlls. In NuGet I can see that their official package ships all these 3 dlls - https://www.nuget.org/packages/Microsoft.Web.Deployment/3.6.0.

Let me check with them to see if the official package contains all these fixes. If it does, will switch websdk to use the official package which will allow us to redist all these 3 dlls.
