After the SQL server2008 is loaded, the Machine.config line136 is always present, or a configuration section system.servicemodel that is not recognized by the configuration error.

Suspect that the problem is caused by a conflict between VS and SQL Server2008 installation.

There is one such argument:

With win8.1 64-bit system, if first installed VS2010, and then installed SQL Server R2, not at all, the initial error.

So first install SQL Server R2 success, and then install vs2010/2013 also successful, then SQL Server MANAGEMEMT Stiduo will not open!

The error is. NETFramework, said to be the exception that occurred in the application's components, the details inside a bunch of exception text, click Continue! Finally, the connection window pops up! Attempt to connect, error message prompt appears again

See the message that it pops up, knowing that the configuration system failed to initialize and that the configuration node (System) could not be recognized. Configuration), (c:\windows\microsoft.net\framework\v2.0.50727\config\machine.config,line136), it seems that the problem is here.

Check online, there is no good solution, or vague. The way I take it is

1) Install SQLSERVER2008R2 First, and then back up the file C:\Windows\Microsoft.NET\Framework\v2.0.50727\CONFIG\machine.config

2) Install the vs2010/2013, and then restore the backup files, the new files are discarded.

With this method, both SQLSERVER2008R2 and vs2010/2013 operate normally.

However, you can use this method to resolve the problem without reinstalling:

Add it to the configsections in the C:/windows/microsoft.net/framework/v2.0.50727/config/machine.config file.
