Cannot initialize type '' with a collection initializer because it does not implement 'System.Collections.IEnumerable'
You are using here the collection initializer in C# :
new myClass{a,b,c} where myClass is a collection, and a,b,c will be inserted into this collection.
But, the notation you need to use is the object initializer:
new myClass{ myProperty1 = a, myProperty2 = b, myProperty3 = c}where the member of a myClass will be initialized. Or maybe you need to use classic constructor and then change your bracket with parenthesis:
new myClass(a,b,c)
