Question

I am getting this error message when ever I try to update or save my Entity Data Model:

ERROR: Unable to register the build provider in Web.Config because of the following exception: 'Object reference not set to an instance of an object.'.

Then when I try to run the application I get:

The specified named connection is either not found in the configuration, not intended to be used with the EntityClient provider, or not valid.

How do I fix it so that it is able to write to the Web.config. I have been through it with a fine tooth comb but I come up with nothing that is XML broken.

You should change the following line

<configuration xmlns="http://schemas.microsoft.com/.NetConfiguration/v2.0">

to

<configuration>

in your web.config file.
