Receiving compilation errors when compiling a class that uses a method with optional parameter
Bug.cs(10,45): error CS1502: The best overloaded method match for `MonoCompilerBug.Bug.MethodWithOptionalParameter<string>(int, string)' has some invalid arguments
Bug.cs(20,33): (Location of the symbol related to previous error)
Bug.cs(10,45): error CS1503: Argument `#2' cannot convert `TValue' expression to type `string'
Compilation failed: 2 error(s), 0 warnings
public class Usage
var bug = new Bug();
string tags = bug.MethodWithOptionalParameter<string>(0);
public class Bug
public TValue MethodWithOptionalParameter<TValue>(int index, TValue defaultValue = null)
This compiles fine under .NET and the CLR.
Fixed in master
