Querying PowerShell for module and cmdlet information

I've recently realized that it's of incredible benefit to start designing our systems such that they're open and easily queryable by any system, particularly .NET and PowerShell. As a result, I've started designing modules for PowerShell to let my team administrate our systems. This has led me to realize that they need some of the basics of PowerShell to query what's available to them, because none of them have really used PowerShell before. The following commands should be of help to beginners:

Show the currently loaded PowerShell modules: Get-Module

Show the available PowerShell modules: Get-Module -ListAvailable

Show the cmdlets available in a particular module: Get-Command -Module [module name]

* in the case of our custom compiled C# module assembly, this is the name of the assembly (not the name of the assembly file, e.g. MyCompany.MyAssembly, not MyCompany.MyAssembly.dll)

Accessing TFS via PowerShell

I'm ashamed to admit that only today did I find out that there are PowerShell cmdlets for TFS.

You can load them into a PowerShell session by executing this:

add-pssnapin Microsoft.TeamFoundation.PowerShell

Once that's done, you can get started with the following commands:

Get-Help Get-TfsServer

AADSTS90093: User cannot consent to web app requesting user impersonation as an app permission.

According to the Azure Graph API team's blog, they've changed the way permissions are handled in Azure AD-authenticating apps.

This error has been driving me nuts for the past month while I've been able to get into an app we're writing in Azure using AD, but my team hasn't.

Here's how we fixed our issue:
1) I could get into our app (because I setup the permissions with my account in the management portal), but my team couldn't.
2) Had to go talk to one of our DevOps guys who's a Global Administrator in our Azure tenant, got him to remove the permission in the Azure AD Application, then re-add it.

Now my team could get in.

Hope this helps anybody stuck on this

SqlPackage.exe fails to deploy to Azure with error "The database platform service with type Microsoft.Data.Tools.Schema.Sql.SqlAzureV12DatabaseSchemaProvider is not valid."

I've recently started trying to deploy to one of my own databases in Azure using SqlPackage.exe. I've used it numerous times at work without problem, but on my own system at home, I keep running into the following error:

"Internal Error. The database platform service with type Microsoft.Data.Tools.Schema.Sql.SqlAzureV12DatabaseSchemaProvider is not valid. You must make sure the service is loaded, or you must provide the full type name of a valid database platform service."

As it turns out, you need at least SSMS CU#6 to get a version of SqlPackage.exe recent enough to deploy to Azure with SQL Azure v12. The copyright on the SqlPackage.exe executable must be 2015 (or later). Such a version comes with the latest versions of SQL Server Data Tools (SSDT). If you're unable to use the version of SqlPackage.exe that comes with SQL Server 2014 because it's too old ("C:\Program Files (x86)\Microsoft SQL Server\120\DAC\bin\SqlPackage.exe"), you can use the version that comes with SSDT for Visual Studio 2013 ("C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE\Extensions\Microsoft\SQLDB\DAC\120\sqlpackage.exe").
