Practice - 5 Tasks

1fill in blank

easy

Complete the code to specify the project SDK in a .csproj file.

C Sharp (C#)

<Project Sdk=[1]>
</Project>

Drag options to blanks, or click blank then click option'

A"Microsoft.NET.Framework"

B"DotNet.Core"

C"Microsoft.NET.Sdk"

D"Microsoft.CSharp.Sdk"

💡 Hint

Common Mistakes

Using incorrect SDK names like "Microsoft.NET.Framework" which is not valid in the SDK attribute.

Forgetting to include quotes around the SDK name.

The Sdk attribute in the Project element specifies the SDK used by the project. For .NET Core and .NET 5+, it is usually "Microsoft.NET.Sdk".

Complete the code to specify the target framework in a .csproj file.

C Sharp (C#)

<PropertyGroup>
  <TargetFramework>[1]</TargetFramework>
</PropertyGroup>

Anet5.0

Bnetstandard2.0

Cnetframework4.7.2

Dnetcoreapp2.1

Attempts:

💡 Hint

Common Mistakes

Using older framework names like "netcoreapp2.1" when targeting newer .NET versions.

Confusing .NET Framework and .NET Core target names.

The TargetFramework element defines which .NET platform the project targets. net5.0 is a common modern target for .NET 5 and later.

Fix the error in the .csproj snippet by completing the blank.

C Sharp (C#)

<ItemGroup>
  <PackageReference Include="Newtonsoft.Json" Version=[1] />
</ItemGroup>

Drag options to blanks, or click blank then click option'

A'12.0.3'

B12.0.3

💡 Hint

Common Mistakes

Omitting quotes around the version number causing XML parsing errors.

Using single quotes which are not standard in XML attributes.

The Version attribute value must be a string enclosed in double quotes in the .csproj XML file.

4fill in blank

hard

Fill both blanks to create a property group that defines the output type and nullable context.

C Sharp (C#)

<PropertyGroup>
  <OutputType>[1]</OutputType>
  <Nullable>[2]</Nullable>
</PropertyGroup>

Drag options to blanks, or click blank then click option'

BLibrary

Cenable

Ddisable

💡 Hint

Common Mistakes

Setting OutputType to 'Library' when the project is an executable.

Using 'disable' for Nullable when you want to enable nullable reference types.

OutputType defines the kind of output the project produces, such as an executable (Exe) or a library (Library). Nullable enables or disables nullable reference types; enable turns it on.

5fill in blank

hard

Fill all three blanks to create a simple .csproj file with SDK, target framework, and output type.

C Sharp (C#)

<Project Sdk=[1]>
  <PropertyGroup>
    <TargetFramework>[2]</TargetFramework>
    <OutputType>[3]</OutputType>
  </PropertyGroup>
</Project>

Drag options to blanks, or click blank then click option'

A"Microsoft.NET.Sdk"

Bnet6.0

CExe

DLibrary

Attempts:

3 left

💡 Hint

Common Mistakes

Using incorrect SDK names or missing quotes.

Choosing an older or incompatible target framework.

Setting OutputType to 'Library' when an executable is intended.

This .csproj file uses the Microsoft.NET.Sdk SDK, targets .NET 6.0 with net6.0, and produces an executable output type Exe.
