    <p>I'm writing a PowerShell module, in PowerShell, which has to redirect an assembly binding. I had no problems using a <code>bindingRedirect</code> in <code>powershell_ise.exe.config</code> but I don't think this is acceptable for a module I want to distribute, so I looked for other ways and came across <a href="http://msdn.microsoft.com/en-us/library/system.appdomain.assemblyresolve%28v=vs.100%29.aspx" rel="nofollow">AppDomain.CurrentDomain.AssemblyResolve</a>. </p> <p>I'm currently using this at the top of my <code>.psm1</code> file:</p> <pre><code>function Resolve-AssemblyRedirect { PARAM ([object]$sender, [System.ResolveEventArgs]$e) PROCESS { $requestedName = New-Object System.Reflection.AssemblyName $e.Name if ($requestedName.Name -eq "System.Net.Http.Primitives") { return [System.Reflection.Assembly]::LoadFrom("$PSScriptRoot\Assemblies\System.Net.Http.Primitives.dll") } return $null } } if (-not $Global:MODULE_LOADED) { [AppDomain]::CurrentDomain.add_AssemblyResolve( { Resolve-AssemblyRedirect $Args[0] $Args[1] } ) Set-Variable -Option Constant -Name MODULE_LOADED -Value $true -Scope Global } </code></pre> <p>I can trigger the problem fairly reliably by using tab-completion/Intellisense in the ISE. I have also seen it in the shell. When I say fairly reliably, it's not always the same cmdlet that triggers it. For example, in preparing this, I've triggered it with Get-ADUser [tab] and most recently, I typed get-por [tab], Intellisense displayed Get-GPOReport and then it hung.</p> <p>If I comment-out the line beginning [AppDomain]::, and hammer tab-completion, I don't see a problem.</p> <p>Before I go on, I want to point out that I've never had to debug anything in PowerShell, before, so there's been quite a bit of fumbling in the dark. In order to debug, I added a <code>REG_SZ</code> to <code>HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AeDebug</code> with the name <code>Auto</code> and the value <code>1</code>, which is giving me the option to start VS 2012. That is then showing me:</p> <blockquote> <p>System.StackOverflowException was unhandled</p> </blockquote> <p>and when I look at the Call Stack I see:</p> <pre><code>mscorlib.dll!System.Resources.ResourceManager.GetString(string name, System.Globalization.CultureInfo culture) + 0x23c bytes System.Management.Automation.dll!System.Management.Automation.ErrorCategoryInfo.Ellipsize(System.Globalization.CultureInfo uiCultureInfo, string original) + 0x88 bytes System.Management.Automation.dll!System.Management.Automation.ScriptBlock.InvokeAsDelegateHelper(object dollarUnder, object dollarThis, object[] args) + 0x137 bytes [Lightweight Function] mscorlib.dll!System.AppDomain.OnAssemblyResolveEvent(System.Reflection.RuntimeAssembly assembly, string assemblyFullName) + 0xbc bytes [Native to Managed Transition] [Managed to Native Transition] mscorlib.dll!System.Reflection.RuntimeAssembly.InternalGetSatelliteAssembly(string name, System.Globalization.CultureInfo culture, System.Version version, bool throwOnFileNotFound, ref System.Threading.StackCrawlMark stackMark) + 0x3ab bytes mscorlib.dll!System.Resources.ManifestBasedResourceGroveler.GetSatelliteAssembly(System.Globalization.CultureInfo lookForCulture, ref System.Threading.StackCrawlMark stackMark) + 0xdd bytes mscorlib.dll!System.Resources.ManifestBasedResourceGroveler.GrovelForResourceSet(System.Globalization.CultureInfo culture, System.Collections.Generic.Dictionary&lt;string,System.Resources.ResourceSet&gt;

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
