Topic 3, Online Bookstore
Background
You are developing an online bookstore web application that will be used by your company's customers.
Technical Requirements
General requirements:
* The web store application must be an ASP.NET MVC application written in Visual Studio.
* The application must connect to a Microsoft SQL database.
* The GetTop100Books() method is mission critical and must return data as quickly as possible. It should
take advantage of fast, forward-only, read-only methods of reading data.
* The ImportBooks() method must keep a copy of the data that can be accessed while new books are
being imported without blocking reads.
* The Create MonthlyTotalsReport() method must lock the data and prevent others from updating or
inserting new rows until complete.
* The college textbook area of the web application must get data from a daily updated CSV file.
* The children's book area of the web application must get data directly from a local database. It must use
a connection string. It must also support access to the stored procedures on the database. Further, it is
required to have strongly typed objects. Finally, it will require access to databases from multiple vendors
and needs to support more than one-to-one mapping of database tables.
* The cookbook functionality is contained within a client-side application that must connect to the server
using HTTP and requires access to the data using JavaScript.
* The BookApiController class must have a method that is able to perform ad-hoc queries using OData.
The RESTful API of the bookstore must expose the following endpoints.
Application Structure
PurchaseOrders.xml
FeaturedBooks.xml

問題11
You are developing a web application that uses an assembly named MyAssembly.
You need to ensure that when MyAssembly version 1.0.0.0 is requested, version 2.0.0.0 is used.
How should you complete the markup in the Web.config file? To answer, drag the appropriate elements to the
correct locations. Each element may be used once, more than once, or not at all. You may need to drag the
split bar between panes or scroll to view content.

Explanation
Box 1: assemblyBinding
Box 2: bindingRedirect
To redirect one assembly version to another, use the <bindingRedirect> element.
Box 3: OldVersion
Box 4: NewVersion
The newVersion attribute should specify a single version. For example, <bindingRedirect
oldVersion="1.1.0.0-1.2.0.0" newVersion="2.0.0.0"/> specifies that the runtime should use version 2.0.0.0
instead of the assembly versions between 1.1.0.0 and 1.2.0.0.
Box 5: assemblyBinding
The following code example demonstrates a variety of binding redirect scenarios. The example specifies a
redirect for a range of versions for myAssembly, and a single binding redirect for mySecondAssembly.
<configuration>
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<dependentAssembly>
<assemblyIdentity name="mySecondAssembly"
publicKeyToken="32ab4ba45e0a69a1"
culture="en-us" />
<bindingRedirect oldVersion="1.0.0.0" newVersion="2.0.0.0" />
</dependentAssembly>
</assemblyBinding>
</runtime>
</configuration>

and receive a NotSupportedException error that includes a table named Customer.
You need to resolve the migration error.
Which four actions should you perform in sequence? To answer, move the appropriate actions from the list of
actions to the answer area and arrange them in the correct order.

正確答案:
Explanation
The SQLite provider has a number of migrations limitations. You can workaround some of these limitations
by manually writing code in your migrations to perform a table rebuild. A table rebuild involves renaming the
existing table, creating a new table, copying data to the new table, and dropping the old table.
