When I try to deploy a small package I get this error:

I'm running the version 4.5 of the framework.

Hi,

This isn't something we've seen before. Can I ask you what version of Powershell you have installed on the target machine?

Powershell version:

Major Minor Build Revision

2 0 -1 -1



Microsoft .Net Framework 4.5

Microsoft SQL Server 2008 R2 (RTM) - 10.50.1600.1 (X64) Apr 2 2010 15:48:46 Copyright (c) Microsoft Corporation Enterprise Edition (64-bit) on Windows NT 6.1 <X64> (Build 7600: ) (Hypervisor)

I'm afraid we're still unable to reproduce this problem. There seems to be something odd about the .NET framework version on your target machine though; the Agent is reporting CLR version 4.0.30319.225, which is a .Net framework 4.0 version, not 4.5. The RTM version of .Net 4.5 should report 4.0.30319.17929.

Can I just check that you've given me the version information from the machine/virtual machine that the Deployment Agent is installed on?

The reason I'm asking this is that the error is occurring while trying to create the Powershell host environment in the Deployment Agent (i.e. on your target machine, not the Deployment Manager server). From the stack trace it looks like there's some sort of mismatch between .Net 4.5 code in the Powershell library (the reference to Task.FromResult, which is a 4.5 specific method) and the framework assemblies loaded into the AppDomain.

I think I got the issue: the machine had a new version of the .NET framework but it's never been rebooted. A reboot fixed it
