DLL support for .NET 4.0

Support both .NET 2.0 and .NET 4 DLL's/assemblies:

notepad/Edit:
$pshome\powershell.exe.config
and
$pshome\powershell_ise.exe.config

<?xml version="1.0" encoding="utf-8" ?>
<configuration>

<startup useLegacyV2RuntimeActivationPolicy="true">

32-bit machines: C:\Windows\System32\WindowsPowershell\v1.0
64-bit machines also have the 32bit version:
32-bit: C:\Windows\SysWOW64\WindowsPowershell\v1.0

Sample/simple c# DLL class

namespace FunLib{
public class MyClass{
public MyClass(){}
public static int StaticSum(int a, int b){
return a + b;
}
public int InstanceProduct(int a, int b){
return a * b;
}
}
}

Call a DLL's static method

[Reflection.Assembly]::LoadFile(“C:\app\DLLs\SharedLib.dll”)

[SharedLib.UtilsGui]::ShowHelpForm();

or

[Reflection.Assembly]::LoadFile(“C:\app\DLLs\SharedLib.dll”)

[SharedLib.UtilsDataBase]::Test();

Call a DLL's instance method

$myInstance = new-object FunLib.MyClass

$myInstance.InstanceProduct(3, 3)

powershell - list static methods and variables

[Reflection.Assembly]::LoadFile(“C:\app\DLLs\SharedLib.dll”)

[SharedLib.UtilsDataBase]|Get-Member -static

TypeName: SharedLib.UtilsDatabase

Name MemberType Definition

---- ---------- ----------

CloseOracleStaticConnection Method static void CloseOracleStaticConnection()

Equals Method static bool Equals(System.Object objA, System.Object objB)

GetCleanSqlWithLineBreaks Method static string GetCleanSqlWithLineBreaks(string sql)

GetColNamesAndTypes Method static System.Collections.Generic.Dictionary[string,string] GetColNamesAndTypes(string sqlString, Oracle.Manag

GetColType Method static string GetColType(Oracle.ManagedDataAccess.Client.OracleDataReader oraReader, int colIdx)

...

show version

[System.Diagnostics.FileVersionInfo]::GetVersionInfo("C:\app\DLLs\SharedLib.dll").FileVersion

call a static method

[SharedLib.UtilsDataBase]::Test();

A better static method call example
C:\app\DLLs>powershell
PS C:\app\DLLs> [Reflection.Assembly]::LoadFile($(get-location).Path +"\SharedLib.dll"); [SharedLib.UtilsGui]::ShowHelpForm();

GAC Version Location
--- ------- --------

PS C:\app\DLLs>

Another example of calling static DLL functions:

Windows PowerShell

PS> [Reflection.Assembly]::LoadFile("C:\app\DLLs\SharedLib.dll")
