Multiple errors usin Reporting R1 2018

[Jaime]

Hi,this is my first time using Telerik Reporting and having some problems....

I added to my Solution a "Telerik Reporting Library R1 2018"

Then added a EDMX file with a couple of tables. Then add a Report "Report1.cs"

Using the Report Designer on Visual Studio:

1.- Add a Entitity DataSource (using the EDMX added before).

2.- Using a table wizard to see the rows of a Table.

When i Press "Preview" tab it shows this error:

Each table row and column maintains a minimum size, resulting in a minimum table
size of {Width=10px, Height=10px}.

And if I try to render it (using c#) to PDF the pdf shows this error too:

An error has occurred while processing Table 'table2':
An error has occurred while resolving 'entityDataSource1' data source: An error occurred while invoking data
retrieval method.
------------- InnerException -------------
No connection string named 'SAOO_ProductionEntities' could be found in the application config file.

But my application Config has the line with the 

<add name="SAOO_ProductionEntities" ..../>

So, wich is the problem? Telerik Reporting have been installed with the MSI package.

Thanks.

Instead of using Entitity DataSource  I used SQl DataSource and works great.

So, perhaps the problem is with the entity DataSource.

Thanks.

After follow this steps:

It's working!!

The designer now works great and the report renders OK.
