Spelling corrections and translations

1. I've corrected the spelling in these lines:
line 175 (look up)
line 190 (multi-)

2. I've translated the missing phrases in the following lines:
line 173 ("Template" would be also appropriate, but I think this lexeme is already used in the WCF context)
line 200-206

3. I've corrected the spelling in line 190 (no capital letter)and changed the preposition due to the meaning.
