You will need PSM Studio and Visual Studio installed.

Open cmd.exe as Administrator and execute setx MSBUILDENABLEALLPROPERTYFUNCTIONS 1.

Run "Developer Command Prompt for VS20XX", navigate to the VitaDefilerClient folder and execute ilasm /output:NativeFunctions.dll /dll NativeFunctions.cil.

Open VitaDefilerClient.sln in PSM Studio and hit F5.

If you get error about NativeFunctions not being resolved (e.g. Error CS0246: The type or namespace name 'NativeFunctions' could not be found [...]):

• Right click VitaDefilerClient / References on the left, select Edit References...
• Edit References window will open. On the right select NativeFunctions and press Remove (trash icon in top right corner).
• Switch to the .Net Assembly tab, navigate to VitaDefiler/VitaDefilerClient, select NativeFunctions.dll and press Add. The project should build now.

Open VitaDefiler.sln in Visual Studio. In Solution Explorer right click VitaDefiler / Properties. Select Reference Paths, then add C:\Program Files (x86)\SCE\PSM\tools\PsmStudio\AddIns\MonoDevelop.Debugger.Soft\ and C:\Program Files (x86)\SCE\PSM\tools\PsmStudio\bin\. You can now press F5 to build the project.

First, copy library dependencies to the VitaDefiler/bin/Debug folder.

• Copy Mono.Cecil.dll from C:\Program Files (x86)\SCE\PSM\tools\PsmStudio\bin
• Copy Mono.Debugger.Soft.dll from C:\Program Files (x86)\SCE\PSM\tools\PsmStudio\AddIns\MonoDevelop.Debugger.Soft
• Copy all files from C:\Program Files (x86)\SCE\PSM\tools\lib

Open PSM Dev application on the Vita. Run cmd.exe and navigate to VitaDefiler folder. Execute bin\Debug\VitaDefiler.exe VitaDefilerClient\bin\Release\VitaDefilerClient.psdp. Vita should now run the VitaDefilerClient app and after a few seconds you will get a RPC shell.
