LINQPad 4/5 Driver for Dynamics CRM Web API is available on CodePlex


I am pleased to announce that we released “LINQPad 4 and 5 Driver for Dynamics CRM Web API” on CodePlex.

https://crmlinqpadwebapi.codeplex.com/

What’s LINQPad?

LINQPad (http://www.linqpad.net/) is a great tool which you can write and execute LINQ query against many data sources, like SQL Server, Oracle or Web Services. In addition to LINQ query support, the tool also supports C#/F#/VB expression, statement block or program, to write and execute the code and code snippet.

What can you do with CRM Driver?

This driver does several things.

- LINQ query against Dynamics CRM organization
- Execute Web API action and function
- Register application to Azure AD for CRM Online

This driver works with Dynamics CRM 2016 On-Premise, IFD and Online, which supports Web API.

Register an application

For IFD environment, you have to register an application before using the driver.

1. Login to AD FS server (You need to use Windows Server 2012 R2 AD FS or later).

2. Open PowerShell

3. Run the following command. You can change name and Guid, but please keep RedirectUri as the driver expects the value.

> Add-AdfsClient -ClientId 5ee98d47-38d1-4db5-b5c2-9a60f88c0076 -Name "CRM For Linqpad" -RedirectUri http://localhost/linqpad

4. Note the ClientId as you use it later.

For Dynamics CRM Online, the driver automatically register an application on your behalf if you have privilege. Otherwise, you can register an application to another Azure AD environment and use consent feature. In that you, you need to register an application in advance and obtain ClientId. Please see following article for detail how to register an application.

Otherwise, leave the checkbox checked.

3. Click “Login to CRM” and login to your Organization at login screen.
Select correct combination for login.

4. If you didn’t pass ClientId for Online environemnt, then it tries to register application to get ClientId. If your user account doesn’t have enough privilege, you may need to ask Azure AD admin to login or let them register and give you the ClientId.

5. Then, it’s downloading data content and generates models. For IFD or consent mode, you will be prompted for authentication.

6. Once “Loading Data” completed, click “Exit”. Then LinqPad starts loading schema, which takes a bit of time. Wait until you see schema information on the left pane like below screenshot.
