Differences between Dotnet2.0 and DotNet1.1:

1. Bulk Copy:

Copying of Data from one data source to
another data source in bulk like the sqlBulkCopy, this can
read as Dataset, Data Table and Data Reader. It provides
the fastest way to transfer the Data.

2. Batch Update:

Batch update can provide a huge
improvement in the performance by making just one round
trip to the server for multiple batch updates, instead of
several trips if the database server supports the batch
update feature. The UpdateBatchSize property provides the
number of rows to be updated in a batch. This value can be
set up to the limit of decimal.


3. Data Paging:

Now command object has a new execute
method called ExecutePageReader. This method takes three
parameters - Command Behavior, start Index, and page Size.
So if you want to get rows from 101 - 200, you can simply
call this method with start index as 101 and page size as
100.

4. Connection Details:
Now you can get more details about a
connection by setting Connection's Statistics Enabled
property to True. The Connection object provides two new
methods - Retrieve Statistics and Reset Statistics. The
Retrieve Statistics method returns a Hash Table object
filled with the information about the connection such as
data transferred, user details, curser details, buffer
information and transactions.

5. DataSet.RemotingFormatProperty:

When DataSet.RemotingFormat is set to
binary, the Dataset is serialized in binary format instead
of XML tagged format, which improves the performance of
serialization and deserialization operations significantly

6. Data Table’s Load and Save Methods:

In this Load method can load data
from objects such as XML in to Database objects and can
save them into the persistent data

7. New Controls:

DataGridView, Data Navigator, Data
Connector.

>inbuild webserver ... no need for iis(which is required in 1.0)
>master pages
> themes and skins,
> navigation controls
>login controls
>datasource controls (now gridview with added features when compared to datagrid in 1.0)
>webparts and also some techniques like improved caching techniques, cross page
>partial class,generics
>page directive include additional attributes
