StructureMap threw an exception after some refactoring
StructureMap Exception Code: 202 No Default Instance defined for PluginFamily IDoSomething
Solved by removing duplicates from assembly scan:
ObjectFactory.Initialize(c =>
{
c.Scan(s =>
{
s.TheCallingAssembly();
// Already loaded with TheCallingAssembly above
// s.AssemblyContainingType<SomethingImplementation>();
s.ConnectImplementationsToTypesClosing(typeof(IDoSomething));
});
});
Turned out the IDoSomething was mapped to 2 implementations (of the same type) and StructureMap could not decide which was the default.

This week I helped out my Business Intelligence colleagues again.
After tackling another problem with a regular expression, the end result contained strange characters. In the output below there is a question mark icon where the Pound (£) sign used to be.
"Whatever returned, � 35.00 debited";3;1;"";0;0
The problem is that the system where the code executes uses a different code page. This messes with the encoding. To solve this we used the Enconding.Default as parameter when reading or writing the text file.
string input = File.ReadAllText(sourceFile, Encoding.Default); // pattern removed for simplicity string output = Regex.Replace(input, pattern, " "); File.WriteAllText(destinationFile, output, Encoding.Default);
After my unit tests showed all green, there was still a bug in my code.
System.NotSupportedException: LINQ to Entities does not recognize the method ‘System.Collections.Generic.IList`1[iCal.ISchedulerEvent] ProcessItem(iCal.ISchedulerEvent)’ method, and this method cannot be translated into a store expression.
Solution is to call the ToList() method to get the data into dotNET.
var possibleResults = DbSet
.Where(item => item.Start < request.End)
.ToList(); // else the link-to-entities will complain
var result = possibleResults
.SelectMany(item => ProcessItem(item))
.OrderBy(item => item.Start)
.FirstOrDefault();
