Description
Summary
When assigning a true literal/primative
.Project(
|
augmentedProductType => new ProductTypeSearchResult |
{
|
isSomething = true |
}
|
)
|
And InvalidOperationException results with the message "Expression not supported: True"
This also occurs when using a where clause in nested select within the project (although the case may be more general than that)
.Project(
|
augmentedProductType => new ProductTypeSearchResult |
{
|
Description = augmentedProductType.ExternalProductTypeDescription,
|
ProductTypeId = augmentedProductType.ProductTypeId,
|
Name = augmentedProductType.Name,
|
ProductFamilyId = augmentedProductType.ProductFamilyId,
|
Url = augmentedProductType.ShopUrl ?? augmentedProductType.TypeUrl,
|
Score = augmentedProductType.Score,
|
Products = augmentedProductType.Products
|
.Select(
|
productForSelect => new ProductSearchResult |
{
|
ProductId = productForSelect.ProductId,
|
ProductInfo = productForSelect.ProductInfo,
|
Deliveries = augmentedProductType
|
.Deliveries
|
.Where(
|
deliveryForWhere =>
|
deliveryForWhere.ProductId ==
|
productForSelect
|
.ProductId)
|
.Select(
|
deliveryForSelect =>
|
new DeliverySearchResult |
{
|
DeliveryId = deliveryForSelect.DeliveryId,
|
Language = deliveryForSelect.Language,
|
Platform = deliveryForSelect.Platform,
|
OperatingSystem = deliveryForSelect.OperatingSystem,
|
ReleaseInfo = deliveryForSelect.ReleaseInfo
|
})
|
})
|
// THIS WHERE CLAUSE CAUSES THE ERROR |
.Where(
|
productSearchResult => productSearchResult.Deliveries != null ) |
