Hi

I'm trying this samples http://www.devart.com/dotconnect/postgr ... _linq.html but when I play the solution I have this errors:
Error 3 La tarea "DevartEntityDeploy" no se pudo cargar desde el ensamblado C:\Program Files (x86)\MSBuild\Devart\v3.5\Devart.Data.Entity.Build.Tasks.dll. No se puede cargar el archivo o ensamblado 'Microsoft.Build.Utilities, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' ni una de sus dependencias. El sistema no puede encontrar el archivo especificado. Confirme que la declaración <UsingTask> sea correcta; que el ensamblado y todas sus dependencias estén disponibles; y que la tarea contenga una clase public que implemente Microsoft.Build.Framework.ITask

Any idea?

Thanks

Please specify the following information:
- what exact Devart products you have installed, their versions and editions;
- select Properties from the shortcut menu of the *.lqml file in your project and specify the value of the "Build Action" property, etc.

If possible, please send us your model with which the error occurs.

I have installed the dotConnect for PostgreSQL 7.2 Professional Trial but I have uninstalled because any kind of ado.net entity framework that I try crash even connections to SQL Server that before the installation works.

I will try again but I'm afraid of....

I'm trying this samples http://www.devart.com/dotconnect/postgr ... _linq.html

This tutorial is for LinqConnect ORM, not for ADO.NET Entity Framework.
Regarding Entity Framework support please refer to http://www.devart.com/dotconnect/postgr ... pport.html

any kind of ado.net entity framework that I try crash even connections to SQL Server

SQL Server support is not available in dotConnect for PostgreSQL. To work with both PostgreSQL and SQL Server, you should have installed Entity Developer product (Professional or Entity Framework edition) in addition to dotConnect for PostgreSQL Professional:

Please specify the exact errors you are getting and the steps you are performing when encountering this errors, so that we are able to advise you.

Sorry I think that you have not understood me

I don´t need to use EntityFramewor with the connector of depart. What I say is that after install it and see that the linnqconnect don't works then the ADO.NET EntityFramework of Microsoft also crashed until I had uninstalled depart

Thanks

Probably, there were some problems with the installation. Please perform the following steps:
- uninstall dotConnect for PostgreSQL and other Devart products, which can use common assemblies (if there are installed);
- clear the Program Files\Devart\dotConnect, Program Files\Devart\Entity Developer and Program Files\Common Files\Devart\dotConnect, Program Files\Common Files\Devart\Entity Developer folders;
- remove all Devart.* and policy.*.Devart.* files from the GAC;
- install dotConnect for PostgreSQL.

Make sure, that during uninstalling/installing all Visual Studio instances are closed.
Also, please specify the following information:
1) what do you mean about "linqconnect doesn't work" - whether you are getting the error from your first post or any other errors;
2) what do you mean about "the ADO.NET EntityFramework of Microsoft also crashed until" - what errors exactly you get;
3) the version and edition of Visual Studio.

Please specify more details about the issues you have encountered, so that we are able to advise you.
