Hallo,

when I want to enter a new database connection in VS Express 2010 using dotConnect, I can only enter the connection string. However, if I enter the connection string as I found here: http://www.connectionstrings.com/postgre-sql
there is an error message saying: "Unknown connection string parameter. Parametername: value"
What am I doing wrong?

It is the correct behaviour, when only PgSqlConnectionString property is available at design time in VS Express: http://www.devart.com/dotconnect/postgr ... ility.html

The class PgSqlConnection does not consider such parameter as Value. You can use our documentation to see the
parameters allowed in the connection string http://www.devart.com/dotconnect/postgresql/docs/ . If this doesn't help, post your connection string (roughly, without credentials) here.

Hallo,
thanks for your reply. As mentionned, I can only enter the connection string. For me it looks like this:

User ID=postgres;Password=admin;Host=localhost;Port=5432;Database=testDB; Pooling=true;Min Pool Size=0;Max Pool Size=100;Connection Lifetime=0;

If I enter this connection string, I get the previously mentionned error message.

I don't know what to do. Thank you for your help.

We could not reproduce your issue with VS Express 2010 and dotConnect for PostgreSQL Express 5.50.237. Please send us the following information to help us reproduce the issue:

1. Where did you exactly enter the connection string?
2. What version and edition of dotConnect for PostgreSQL do you use?
3. Please send us the steps that lead to this exception.

1. Add Connection - Properties (see 3.)
2. I have the latest version (I guess 5.50) which I downloaded last friday, it's dotconnect postgresql express
3. I click on New Connection in the database explorer, then I enter postgre SQL server as data source and select dotConnect for postgreSQL. In the next window I can define properties (in this case just one: Connection String), Test Connection completes successfully (even if I enter no connection string), after clicking on OK, the message occurs

@edit: As I tried to reproduce it now, I get a different message: File or assembly "Devart.Data, Version =5.0.336.0, Culture = neutral, PublicKeyToken=09af7300eec23701" or one of its dependencies cannot be found

Perform the following steps:
1. uninstall dotConnect for PostgreSQL;
2. remove all Devart.* and policy.*.Devart.* files from the GAC;
3. clear the Program Files\Devart\dotConnect and Program Files\Common Files\Devart\dotConnect folders;
4. re-install dotConnect for PostgreSQL.

We are working on the issue with Visual Studio Web Developer Express. We can offer you a workaround.
If the \Program Files\Microsoft Visual Studio 10.0\Common7\IDE\VWDExpress.exe.config file exists, then you have to add the following entries to the element. If you do not have \Program Files\Microsoft Visual Studio 10.0\Common7\IDE\VWDExpress.exe.config, you should create it and enter the following information:
