"defined in an assembly that is not referenced." error help

1

Hey everyone! I’ve finally decided to take the leap and port my current project from XNA 4.0 to Monogame. I tested the waters with an older, smaller project and all went well so I went ahead with transitioning my current larger project over and I’ve run into a strange error.

Here is the section of code in which the error pops up.

if (!SaveLoad.SaveFile.isStorageDeviceLoaded)
                {
                    EasyStorageSettings.SetSupportedLanguages(Language.English);

                    //create and add SaveDevice
                    SharedSaveDevice sharedSaveDevice = new SharedSaveDevice();
                    RogueLike.Systems.Engine.Instance.Components.Add(sharedSaveDevice);
                    //make sure we hold onto the device
                    saveDevice = sharedSaveDevice;

                    sharedSaveDevice.DeviceSelectorCanceled +=
                        (s, e) => e.Response = SaveDeviceEventResponse.Force;
                    sharedSaveDevice.DeviceDisconnected +=
                        (s, e) => e.Response = SaveDeviceEventResponse.Force;

                    //prompt for a device on the first update we can
                    sharedSaveDevice.PromptForDevice();
                    sharedSaveDevice.DeviceSelected += (s, e) =>
                        {
                            SaveLoad.SaveFile.SaveDevice = (SaveDevice)s;
                        };

                    SaveLoad.SaveFile.isStorageDeviceLoaded = true;
                }

So the error itself takes place in the section where I am attempting to create a SharedSaveDevice and add it to Components. The error message I receive are as follows.

Error 1 The type ‘Microsoft.Xna.Framework.IUpdateable’ is defined in an assembly that is not referenced. You must add a reference to assembly ‘Microsoft.Xna.Framework.Game, Version=4.0.0.0, Culture=neutral, PublicKeyToken=842cf8be1de50553’.

Error 2 The type ‘Microsoft.Xna.Framework.IGameComponent’ is defined in an assembly that is not referenced. You must add a reference to assembly ‘Microsoft.Xna.Framework.Game, Version=4.0.0.0, Culture=neutral, PublicKeyToken=842cf8be1de50553’.

Error 3 The best overloaded method match for ‘System.Collections.ObjectModel.Collection<Microsoft.Xna.Framework.IGameComponent>.Add(Microsoft.Xna.Framework.IGameComponent)’ has some invalid arguments

Error 4 Argument 1: cannot convert from ‘EasyStorage.SharedSaveDevice’ to ‘Microsoft.Xna.Framework.IGameComponent’

I tried looking online and the closest thing to an answer I’ve found is that I may need to recomplie my DLL game library after changing all the XNA references to MonoGame references.

I’m not sure what that means as I thought that MonoGame still uses all the same namespaces. Any help on this would be greatly appreciated!

I think I figured it out.
The EasyStorage project was referencing various XNA frameworks instead of monogame. Once I removed the XNA references and replaced it with MonoGame, it fixed that problem. Just in case anyone experiences simliar issues, that may be a good starting point =]

Hi, I’m using EasyStorage as well but I keep getting the following error in IsolatedStorageSaveDevice.cs:

The name ‘ThreadPool’ does not exist in the current context
