## Definition

**Assembly:** Microsoft.OData.Mcp.Core.dll

**Namespace:** Microsoft.OData.Mcp.Core.Models

**Inheritance:** System.Object

## Syntax

```csharp theme={"dark"}
Microsoft.OData.Mcp.Core.Models.EdmEntityType
```

## Summary

Represents an entity type in an OData model.

## Remarks

Entity types define the structure of entities in an OData service, including their
properties, navigation properties, and key definitions. They form the foundation
of the entity data model and determine how data is structured and accessed.

## Constructors

### <Icon icon="hammer" iconType="duotone" color="#419AC5" size={24} style={{ paddingRight: '8px' }} />  .ctor

Initializes a new instance of the [EdmEntityType](/odata-mcp/api-reference/Microsoft/OData/Mcp/Core/Models/EdmEntityType) class.

#### Syntax

```csharp theme={"dark"}
public EdmEntityType()
```

### <Icon icon="hammer" iconType="duotone" color="#419AC5" size={24} style={{ paddingRight: '8px' }} />  .ctor

Initializes a new instance of the [EdmEntityType](/odata-mcp/api-reference/Microsoft/OData/Mcp/Core/Models/EdmEntityType) class with the specified name and namespace.

#### Syntax

```csharp theme={"dark"}
public EdmEntityType(string name, string namespace)
```

#### Parameters

### <Icon icon="hammer" iconType="duotone" color="#419AC5" size={24} style={{ paddingRight: '8px' }} />  .ctor <DocsBadge text="Inherited" variant="neutral" />

<Note>Inherited from `object`</Note>

#### Syntax

```csharp theme={"dark"}
public Object()
```

## Properties

### <Icon icon="tag" iconType="duotone" color="#419AC5" size={24} style={{ paddingRight: '8px' }} />  Abstract

Gets or sets a value indicating whether this entity type is abstract.

#### Syntax

```csharp theme={"dark"}
public bool Abstract { get; set; }
```

#### Property Value

Type: `bool`
`true` if the entity type is abstract; otherwise, `false`.

#### Remarks

Abstract entity types cannot be instantiated directly but can serve as base types
for other entity types. They are useful for defining common properties and behaviors.

### <Icon icon="tag" iconType="duotone" color="#419AC5" size={24} style={{ paddingRight: '8px' }} />  BaseType

Gets or sets the base type of the entity type.

#### Syntax

```csharp theme={"dark"}
public string BaseType { get; set; }
```

#### Property Value

Type: `string?`
The fully qualified name of the base entity type, or `null` if this type has no base type.

#### Remarks

When specified, this entity type inherits all properties and navigation properties
from the base type. The inheritance hierarchy must be consistent within the model.

### <Icon icon="tag" iconType="duotone" color="#419AC5" size={24} style={{ paddingRight: '8px' }} />  FullName

Gets the fully qualified name of the entity type.

#### Syntax

```csharp theme={"dark"}
public string FullName { get; }
```

#### Property Value

Type: `string`

### <Icon icon="tag" iconType="duotone" color="#419AC5" size={24} style={{ paddingRight: '8px' }} />  HasBaseType

Gets a value indicating whether this entity type inherits from another entity type.

#### Syntax

```csharp theme={"dark"}
public bool HasBaseType { get; }
```

#### Property Value

Type: `bool`
`true` if the entity type has a base type; otherwise, `false`.

### <Icon icon="tag" iconType="duotone" color="#419AC5" size={24} style={{ paddingRight: '8px' }} />  HasNavigationProperties

Gets a value indicating whether this entity type has any navigation properties.

#### Syntax

### <Icon icon="tag" iconType="duotone" color="#419AC5" size={24} style={{ paddingRight: '8px' }} />  HasStream

Gets or sets a value indicating whether this entity type has a stream.

#### Syntax

```csharp theme={"dark"}
public bool HasStream { get; set; }
```

#### Property Value

Type: `bool`
`true` if the entity type has a stream; otherwise, `false`.

#### Remarks

When true, instances of this entity type can have an associated media resource
(such as a photo or document) that can be accessed via streaming operations.

### <Icon icon="tag" iconType="duotone" color="#419AC5" size={24} style={{ paddingRight: '8px' }} />  IsAbstract

Gets a value indicating whether this entity type is abstract.

#### Syntax

```csharp theme={"dark"}
public bool IsAbstract { get; }
```

#### Property Value

Type: `bool`
`true` if the entity type is abstract; otherwise, `false`.

#### Remarks

This is an alias for the [EdmEntityType.Abstract](/odata-mcp/api-reference/Microsoft/OData/Mcp/Core/Models/EdmEntityType#abstract) property for compatibility.

```

#### Property Value

Type: `System.Collections.Generic.List<Microsoft.OData.Mcp.Core.Models.EdmNavigationProperty>`
A collection of navigation properties that define relationships to other entities.

#### Remarks
