problem in PowerShell and Visual Studio, yet cases and solutions seem to vary a lot. Though seeing several similar questions, I didn't find a working solution for my issue yet.

(Exception from HRESULT: 0x80131515) The file location is invalid, as the .dll is supposed to be located in the same

It contains some properties and methods I would could not load like to take advantage of in my Powershell script(s). However, I am running into a lot of issues with first loading the assembly, then using any of the types once the assembly is loaded. The complete file path is: C:\rnd\CloudBerry.Backup.API.dll In Powershell I use: $dllpath = "C:\rnd\CloudBerry.Backup.API.dll" Add-Type -Path $dllpath I get the error below: Add-Type : Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information. At line:1 char:9 + Add-Type <<<< -Path $dllpath + CategoryInfo : NotSpecified: (:) [Add-Type], ReflectionTypeLoadException + FullyQualifiedErrorId : System.Reflection.ReflectionTypeLoadException,Microsoft.PowerShell.Commands.AddTypeComma ndAdd-Type : Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information. Using the same cmdlet on another .NET assembly, DotNetZip, which has examples of using the same functionality on the site also does not work for me. I eventually find that I am seemingly able to load the assembly using reflection: [System.Reflection.Assembly]::LoadFrom($dllpath) Although I don't understand the difference between the methods Load, LoadFrom, or LoadFile that last method seems to work. However, I still seem to be unable to create
in general, so I'm going to keep this one specific to our Powershell deployment scripts. We build our code to a central server and then use Powershell to install those build on our Development server. The upgrade to .NET 4 caused 2 problems with Powershell when we called [Reflection.Assembly]::LoadFile() First: Powershell by default runs in .NET 2.0. When we tried to load our new 4.0 assemblies, we got this error:
Exception calling "LoadFile" with "1" argument(s): "Could not load file or assembly 'file://\\buildServer\Application\assembly.dll' or one of its dependencies. This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded."
At C:\Scripts\Deployment\Deploy.ps1:XX char:XX
+ $assembly = [Reflection.Assembly]::LoadFile <<<< ($file); + CategoryInfo : NotSpecified: (:) [], ParentContainsErrorRecordException + FullyQualifiedErrorId : DotNetMethodException We need to tell Powershell to run in .NET 4.0 mode. To do that we need to create an app.config file for Powershell. In our case the file was created here: C:\WINDOWS\system32\windowspowershell\v1.0\powershell.exe.config, but YMMV based on Powershell's location. The new powershell.exe.config file looks like this:
 
Now Powershell can run with both 2.0 and 4.0 assemblies. Second: The security features are a bit different when running 2.0 vs 4.0. This difference caused a problem when running assemblies from our Build server on our Development server:
Exception calling "LoadFile" with "1" argument(s): "An attempt was made to load an assembly from a network location which would have caused the assembly to be sandboxed in previous versions of the .NET Framework. This release of the .NET Framework does not enable
