Answer 1

I kept getting the 'could not find data type' error and it was driving me nuts. Try this -

When you're adding a data source and you get to the part where you select tables and the such to include don't click anything, leave them all empty. It will ask if you want to create an empty dataset, say yes and an empty dataset will show up in your data sources window. Then configure the dataset with the wizard and add your items.

Worked for me anyway. Good luck!

Hi,@Howard Burton. Welcome Microsoft Q&A.

"An error occurred while creating the new data source: 'Could not get type information for 'Church_Video_InventoryDataSet','" suggests that there may be an issue with the data source configuration in your project.

Here are some steps to troubleshoot and resolve the issue:

1.Open the DataSet designer (typically a .xsd file) and verify that it exists and is properly configured.

2.Sometimes, rebuilding the project can resolve issues related to missing type information.

3.Verify that the dataset and related components are in the correct namespace that matches your project's namespace.

4.Ensure that you have all the required references in your project. Right-click on your project, select "Add," and then choose "Reference..." to check that all necessary references are included.

5.If you are configuring a data source in Visual Studio, double-check that you've selected the correct dataset and that the dataset has been successfully built.

6.Clean and Rebuild Solution.

7.Sometimes, Visual Studio can encounter temporary glitches. Try closing and reopening Visual Studio to see if the issue persists.

8.Ensure that all project components, including the dataset, are compatible with the target .NET Framework version (4.7.2 in your case). Mismatched versions can lead to issues.

9.Ensure that your Visual Studio installation and all extensions are up to date. Outdated components can sometimes cause compatibility issues.

10.Check any configuration files (e.g., app.config or web.config) for correctness, especially if your dataset is used in a specific context like ASP.NET.

11.If you are using a specific data source like SQL Server or Entity Framework, ensure that the data source connection and properties are correctly configured.
