错误 MC3066：类型引用找不到名为“StoreDb”的公共类型。 9号线 Position 94

Question

I download the source code of book from github here .

I am building DataBinding project in chapter 19 but it doesn't build and I get this compilation error.

error MC3066: The type reference cannot find a public type named 'StoreDb'. Line 9 Position 94.

<Window x:Class="DataBinding.BindToObjectDataProvider"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="BindToObjectDataProvider" Height="450" Width="400"
    xmlns:data="clr-namespace:StoreDatabase;assembly=StoreDatabase" 
    >
  <Window.Resources>
    <ObjectDataProvider ObjectType="{x:Type data:StoreDb}"                         
                       MethodName="GetProductsSlow" x:Key="products" IsAsynchronous="True"></ObjectDataProvider>
  </Window.Resources>

Can anyone see why it doesn't build? Thank you!

I am using Visual Studio 2019.

Answer 1

I had copied the chapter 19 folder (where the project was) to another folder to build/run/play with so I don't modify the original but it required StoreDatabase project which was in root folder.

I tried to build the project on another PC that gave me a clue, it had an error that one project was not loaded. Copied that project to root fixed it.

This was the error loading solution.

C:\Projects\StoreDatabase\StoreDatabase.csproj: error: The project file could not be loaded. Could not find a part of the path 'C:\Projects\StoreDatabase\StoreDatabase.csproj'. C:\Projects\StoreDatabase\StoreDatabase.csproj
