MVC配置种子方法未插入指定的主键

I am working with MVC 4 doing a side project. In my Configuration.cs I have my Seed method coded out and it works fine except for one thing. The table is completely empty with no records in it. I specify that I want the PK ID to start at 100001 for tracking purposes. I update the database and the record is created but the PK value for ID is just 1. If I make changes and update it again then the ID is 2. It is not taking my specified PK value and I cannot figure out why. I should be able to specify any PK value I want as long as it falls within the data constraints and is unique. Is this not able to be done or am I missing something? Can you define what value you want the ID to start and then increment from there? Any help is appreciated. I am working with MVC 4 doing a side project. I
