One little known feature of PowerShell Pro Tools is that you can create P\Invoke signatures using the Convert From C# function. This can be done in Visual Studio, VS Code and on the command line.

To create a P\Invoke Signature, you first need to get the C# representation. The easiest way to do this is from You can search for a signature, such as MiniDumpWriteDump, and copy the code for that signature.

static extern bool MiniDumpWriteDump(IntPtr hProcess, uint ProcessId, IntPtr hFile, int DumpType, ref MINIDUMP_EXCEPTION_INFORMATION ExceptionParam, IntPtr UserStreamParam, IntPtr CallbackParam);

Next, depending on the environment, you can use the following methods to convert the code into PowerShell.

Convert in Visual Studio

In Visual Studio, directly from the clipboard, you can paste the C# code as PowerShell. This will perform the conversion and then PowerShell script will be pasted into the file.

In Visual Studio Code, you can create a C# file (.cs) with the P\Invoke signature. If you then execute the Convert To PowerShell command, the P\Invoke signature will be converted into PowerShell script.

Convert on the Command Line

Requires PowerShell Pro Tools PowerShell Module

Using the ConvertTo-PowerShell cmdlet, you can select a C# file (.cs) and the cmdlet it then convert the P\Invoke signature to PowerShell.
