C# get all string combinations between 2 arrays

I have 2 string arrays:

string[] baseAssemblyNames

For instance ['Core', 'Web', 'Data']

string[] projectAssemblyNames

For instance ['Project1', 'Project2']

Result:

['Project1.Core', 'Project1.Web', 'Project1.Data', 'Project2.Core', 'Project2.Web', 'Project2.Data']

I want all combinations between these 2, now I am using 2 foreach to iterate and combine them.

        foreach(var projectAsm in projectAssemblyNames)
        {
            foreach(var baseAsm in baseAssemblyNames)
            {
                try
                {
                    var asm = Assembly.Load($"{projectAsm}.{baseAsm}");
                    asmList.Add(asm);
                }
                catch { }
            }
        }

Is there a better solution for this in terms of performance when we have a lot of projects where we want to load the assembly for scanning.
