Googling your own question
Some years ago I googled a question just to find my own answer.
Right now it happened again. Wasted 2 hours for finding the question and answer I already had gotten an answer for.
It was about AspnetMvc and Model and Actionresult and Modelstate and Modelstate.clear and Modelstate.Remove and Return View. So next time I can google my own blog to find my own question to find the answer.
