When using decimal literals: "The operands for operator 'Equal' do not match the parameters of method 'op_Equality'."

I have a NUMBER(28,12) column mapped to a decimal? property. The following code throws a System.InvalidOperationException: 'The operands for operator 'Equal' do not match the parameters of method 'op_Equality'.'

Code: Select all

Console.WriteLine(ctx.Test.Where(z => z.Num == 5m).Count());
On the other hand, the following code works correctly:

Code: Select all

decimal d = 5m;
Console.WriteLine(ctx.Test.Where(z => z.Num == d).Count());
