You are given a code snippet that contains a method named `GetVisibleTypesFromAssemblies`. This method takes in a collection of `Assembly` objects and returns a list of `Type` objects. However, the implementation of the method is incomplete and it is missing the definition of the `GetFilteredTypesFromAssembly` method, which is used to filter the types obtained from each assembly.

Your task is to complete the implementation of the `GetVisibleTypesFromAssemblies` method by implementing the missing `GetFilteredTypesFromAssembly` method. 

The `GetFilteredTypesFromAssembly` method should take in an `Assembly` object and a `filter` parameter and return a filtered list of `Type` objects based on the given filter. The filter is a delegate that takes a `Type` object as input and returns a `bool` indicating whether the type should be included in the filtered list or not.

You need to write the implementation for the `GetFilteredTypesFromAssembly` method.

**Signature**
```
public static List<Type> GetFilteredTypesFromAssembly(Assembly assembly, Func<Type, bool> filter)
```

**Input**
- `assembly` (1 ≤ assembly ≤ 100): An `Assembly` object representing an assembly. You can assume that it is not `null`.
- `filter`: A delegate that takes a `Type` object as input and returns a `bool` indicating whether the type should be included in the filtered list or not. You can assume that it is not `null`.

**Output**
The method should return a filtered list of `Type` objects based on the given filter.

**Note**
- The `GetVisibleTypesFromAssemblies` method takes a collection of `Assembly` objects, and for each assembly, it calls the `GetFilteredTypesFromAssembly` method to obtain the filtered types. The filtered types from all the assemblies are then returned as a list.

**Example**
```
Input:
- assemblies: [AssemblyA, AssemblyB]
- filter: (type) => type.Name.StartsWith("My")

Output:
- List containing the types from the assemblies that have a name starting with "My"
```

Sure, I can provide a simple implementation for the `GetFilteredTypesFromAssembly` method based on your requirements.

Here's a generic version of the method that should work for any type that implements the `ICollection` interface (e.g. Collection, List, etc.). It returns an `ICollection` instead of a list, but you can easily convert it to a list if needed.

```csharp
public static ICollection<Type> GetFilteredTypesFromAssembly(Assembly assembly, Func<Type, bool> filter)
{
    var types = assembly.GetTypes();

    // Filter the types
    var filteredTypes = types.Where(filter).ToList(); // ToList() is necessary to use Where

    return filteredTypes;
}
```

This method uses LINQ's `Where` method to filter the types based on the given filter expression. The `Where` method returns an `IEnumerable` of the filtered types, so we convert it to a list using the `ToList` method.

Note that this method uses the `GetTypes` method of the `Assembly` class, which returns all public and non-public types in the assembly. If you only want to see visible types (i.e. Public types), you can use the `GetExportedTypes` method instead.

I hope this helps you complete the `GetVisibleTypesFromAssemblies` method as well. Good luck with your project!

Sure, I can help you implement the `GetFilteredTypesFromAssembly` method. Here's a simple implementation:

```csharp
public static List<Type> GetFilteredTypesFromAssembly(Assembly assembly, Func<Type, bool> filter)
{
    // Get all types from the assembly
    Type[] types = assembly.GetTypes();

    // Filter the types based on the provided filter delegate
    List<Type> filteredTypes = types.Where(filter).ToList();

    return filteredTypes;
}
```

This method first gets all types from the given assembly using the `GetTypes` method. Then it applies the provided filter delegate to these types using the `Where` LINQ method. The `Where` method returns a new collection with only those types for which the filter returns `true`. This filtered collection is then converted to a list and returned.

The `GetVisibleTypesFromAssemblies` method can then use this `GetFilteredTypesFromAssembly` method to get the filtered types from each assembly. Here's an example of how it might look:

```csharp
public static List<Type> GetVisibleTypesFromAssemblies(ICollection<Assembly> assemblies, Func<Type, bool> filter)
{
    // For each assembly, get the filtered types and add them to the list
    List<Type> visibleTypes = assemblies.SelectMany(assembly => GetFilteredTypesFromAssembly(assembly, filter)).ToList();

    return visibleTypes;
}
```

In this method, the `SelectMany` LINQ method is used to apply the `GetFilteredTypesFromAssembly` method to each assembly in the collection. The `SelectMany` method returns a flat list of all the filtered types from all the assemblies. This list is then returned.
