Embedding Powershell v2.0 in .NET app on Windows 8 RTM

Question

Im getting the following error when trying to run hosted powershell scripts before upgrading from Windows 7 I never got this error.

The following error occurred while loading the extended type data file: Microsoft.PowerShell.Core, C:\Windows\SysWOW64\WindowsPowerShell\v1.0\types.ps1xml(2977) : Error in type "System.Security.AccessControl.ObjectSecurity": Exception: The getter method should be public, non void, static, and have one parameter of type PSObject. Microsoft.PowerShell.Core, C:\Windows\SysWOW64\WindowsPowerShell\v1.0\types.ps1xml(2984) : Error in type "System.Security.AccessControl.ObjectSecurity": Exception: The getter method should be public, non void, static, and have one parameter of type PSObject. Microsoft.PowerShell.Core, C:\Windows\SysWOW64\WindowsPowerShell\v1.0\types.ps1xml(2991) : Error in type "System.Security.AccessControl.ObjectSecurity": Exception: The getter method should be public, non void, static, and have one parameter of type PSObject. Microsoft.PowerShell.Core, C:\Windows\SysWOW64\WindowsPowerShell\v1.0\types.ps1xml(2998) : Error in type "System.Security.AccessControl.ObjectSecurity": Exception: The getter method should be public, non void, static, and have one parameter of type PSObject. Microsoft.PowerShell.Core, C:\Windows\SysWOW64\WindowsPowerShell\v1.0\types.ps1xml(3005) : Error in type "System.Security.AccessControl.ObjectSecurity": Exception: The getter method should be public, non void, static, and have one parameter of type PSObject.

I have applied the following in App.config:

<dependentAssembly>   <assemblyIdentity name="System.Management.Automation" publicKeyToken="31bf3856ad364e35" />   <publisherPolicy apply="no" /> </dependentAssembly> 

What could the issue be?

Answer 1

The solution is to do the following, rather than only adding a block for only System.Management.Automation as suggested by the posts I read, you need to add one for all referenced PS assemblies.

  <runtime>       <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">         <dependentAssembly>             <assemblyIdentity name="System.Management.Automation" publicKeyToken="31bf3856ad364e35" />             <publisherPolicy apply="no" />           </dependentAssembly>         <dependentAssembly>           <assemblyIdentity name="Microsoft.PowerShell.Commands.Utility" publicKeyToken="31bf3856ad364e35" />           <publisherPolicy apply="no" />         </dependentAssembly>         <dependentAssembly>           <assemblyIdentity name="Microsoft.PowerShell.ConsoleHost" publicKeyToken="31bf3856ad364e35" />           <publisherPolicy apply="no" />         </dependentAssembly>         <dependentAssembly>           <assemblyIdentity name="Microsoft.PowerShell.Commands.Management" publicKeyToken="31bf3856ad364e35" />           <publisherPolicy apply="no" />         </dependentAssembly>         <dependentAssembly>           <assemblyIdentity name="Microsoft.PowerShell.Security" publicKeyToken="31bf3856ad364e35" />           <publisherPolicy apply="no" />         </dependentAssembly>         <dependentAssembly>           <assemblyIdentity name="Microsoft.PowerShell.Commands.Diagnostics" publicKeyToken="31bf3856ad364e35" />           <publisherPolicy apply="no" />         </dependentAssembly>         </assemblyBinding>     </runtime>
