Thank you for the report. We have reproduced this issue in Visual Studio 2012 (JIC: it works in Visual Studio 2010). We will investigate this issue and inform you about the results as soon as possible.

Also, please pay attention to our LINQ Insight product, which allows executing LINQ queries at design-time directly from Visual Studio without starting a debug session.

I test Linq Insight but when i run linq query in design time throws an exception

Im using visual studio 2012 as admin and connection string exists in app.config, the code run ok (dotConect MySql (LinqConnect Model)), but at design time linq insight throws an exception


The type initializer for 'MultiGps.HistoryBackup.Program' threw an exception.

Connection string "MultigpshistoryDataContextConnectionString" could not be found in the configuration file.
System.InvalidOperationException

The last issues only happens under windows 7
(DotConnect Mysql Debugger Visualizer and Linq Insight Exceptions)

Under Windows 8 are both OK

Both (Win7 and Win8) have installed VS 2012 and the same project test (in netfx4)

I hope helps!

We couldn't reproduce this issue with the latest version of LINQ Insight 2.0.22.
Please specify the version of LINQ Insight you are using.
JIC: the bug related to the "Could not find the connection string '...' in the configuration file" exception has been fixed in LINQ Insight 1.0.19.

Im using Linq Insight 2.0.22, the exception throws only in Win7
In Win8 works ok

Sorry for the delay. We couldn't reproduce this issue on Windows 7.
Please send us a small test project, so that we are able to reproduce it.
